<p align="left">A dive boat is a  boat that scuba divers use to reach a diving site which they could not reach by  swimming from land.<br>
  <br>
  Many types of boat  can be used as dive boats. Some notable types of dive boat are:<br>
  The rigid-hulled <a href="http://www.china-inflatable.com/products/boat/boats_inflatable_kayak.htm">inflatable  boat</a> <br>
  The day boat <br>
  The live aboard <br>
  <br>
  Rigid-hulled  inflatable boat (RIB)<br>
  Divers only spend a  few hours at a time on these fast but exposed <strong>boats</strong>. The boat being small and easily transported on roads is  suitable for amateur use. These boats should carry basic safety equipment such  as marine VHF radio and oxygen first aid.<br>
  The divers enter  the water by rolling backwards over water side and return to the boat by  climbing back in over the soft rounded tubes after removing the heavy parts of  their heavy diving equipment and handing it up. An advantage of this type of  boat compared with similar-sized rigid boats is that the inflated tubes make  the boat very stable during the entry and exit of the divers.<br>
  <br>
  Day boat<br>
  These boats are  made of rigid materials - often, fiber glass. Day <strong>boats</strong> are quite large: typically, between 60 to 90 feet (27 m) in  length. Many day boats are used for scuba-divers, but may also be used for any  other marine enthusiasts. In general, divers or passengers will spend only the  daylight hours on a day boat, and do not usually sleep in them overnight. (They  will usually only sleep overnight if they are on a &quot;live-aboard&quot;,  which is a slightly different sort of boat). Generally a professional crew  navigates and operates the boat. The boat provides shelter from the weather and  is likely to have various facilities and area's for the passengers, such as: a toilet  (called the &quot;head&quot;) and a small kitchen (called a  &quot;galley&quot;), which is often manned by a cook who cooks lunch for all on  the boat. Day-boats usually also have a lounge (called a &quot;saloon&quot;,  where divers can relax on upholstered benches), and one or more dining tables.  Many day boats also have an uncovered sun-deck outside, as well as a shaded  area, for divers wishing to be out in the open air. The boat will usually have  a diving air compressor, oxygen first aid, a VHF radio, a GPS and possibly gas  blending facilities. In the case of divers, a day boat would be used to ferry  divers to multiple dive-sites (typically between 1 and 3 sites) during the same  day.</p>
<p align="left">The divers enter  the water by stepping off a platform and return to the boat using a ladder or a  lift. Or they may transfer to and from a RIB (&quot;Zodiac&quot;(tm) or  &quot;rubber-duck&quot; type <a href="http://www.china-inflatable.com/">inflatable</a> boat).<br>
  <br>
  Liveaboard<br>
  With these  commercial <strong>boats</strong>, the divers live  and sleep on the boat and dive from the boat for a few days to several weeks. A  crew navigates and operates the boat. In addition to the usual domestic  facilities expected by hotel guests, the boat will have a diving air  compressor, oxygen first aid and possibly gas blending facilities and even a  recompression chamber in some cases.</p>

An inflatable Bounce house is a fun and creative way to bring enjoyment to almost any kind of party, event and so on. Not only are Bounce houses relatively cheap when you consider their size and the amount of people they can entertain; they are also safe and popular with adults and children alike. There are some main different types of bounce houses here: Children's Obstacle Courses - Bounce houses which shape like obstacle courses are great for those who want to experience more than just bouncing around. They are much greater when it comes to making fun games to participate while on the Bounce house.

Basketball Court - What better way to score a slam dunk, than when you are able to leap 6 feet into the air thanks to the inflatable castle that you are on. An inflatable Bounce castle which has basketball court is the perfect solution for many youngsters who enjoy both activities. Bungee Run - Experience running when attached to a stretchy rope that can only be stretched so much! This is fun for those that are really competitive and think that they have the enough strength to go the distance.

Slide - For those who would rather jump down a Bounce house which is at a gradient, you should consider a Bounce house slide. They have a variety of heights and gradients so you can be sure to find the right one that you are looking for. Character - If you have a character/theme that your children particularly like, then why not getting a Bounce house specific to that? For an example, you can get princess and clown castles, so make your decision to choose the available one.

Events for Which Bounce Houses are perfect: Kid's Birthday Parties - What better way to celebrate a kid's birthday than with a Bounce castle for them to enjoy. Not only will it keep the children and their guests entertained, but also will not have to worry about what they are up to since they will all be in one same place.

Theme Parks and Carnivals - If you are organizing a special day for a large crowd then a Bounce house can really steal the show. It not only provides an outlet for younger children to enjoy themselves, but also adds to the atmosphere of the park tremendously.

Whatever occasion you wish to use a Bounce house for, ensure that you know exactly what you are getting. And most importantly...ensure the kids have a great day!

Bossaball is a sport invented in Belgium. It is similar to volleyball, but also includes elements of football (soccer), gymnastics and capoeira.1 Each side of the court has an integrated trampoline, allowing players to bounce high enough to spike the ball, and a number of inflatable barriers.

Bossaball clubs exist in various countries including Brazil, Germany5, Netherlands, Spain, Portugal, Romania, Singapore, Kuwait, Ecuador and Saudi Arabia.

Game play
Each team consists of 3 to 5 players. One player (the attacker) is positioned in the trampoline, the others around him on the inflatables. A player from the serving team (the server) throws or kicks the ball into the air and attempts to hit the ball so it passes over the net on a course such that it will land in the opposing team's court (the serve). The opposing team must use a combination of no more than 8 contacts with the ball to return it to the opponent's side of the net. These contacts can be exercised using any body part (maximum 2 successive contacts with the head or feet, maximum one contact with the hands). During a rally the ball is tossed around while the attacker jumps on the trampoline in order to gain height. The attack begins when one of the rallying players aims the ball's trajectory towards a spot in the air where the attacker can hit it (spike or kick) and returns the ball over the net.

The team with possession of the ball that is trying to attack the ball as described is said to be on offense. The team on defense attempts to prevent the attacker from directing the ball into their court: players at the inflatable jumper and reach above the top (and across the plane) of the net in order to block the attacked ball. If the ball is hit around, above, or through the block, the defensive players arranged in the rest of the court attempt to control the ball with a dig (usually a fore-arm pass of a hard-driven ball, or a foot control). After a successful dig, the team transitions to offense

The game continues in this manner, rallying back and forth, until the ball touches the court within the scoring zones.

Scoring
When the ball contacts the floor (the bottom of the trampoline or the inflatables) within the court boundaries, the team on the opposite side of the net is awarded a score. 3 Points are assigned for scoring on the trampoline. 1 point is assigned for scoring on the inflatable cushions, except for the bossa wall which is the ring around the trampoline. When the ball touches the bossa wall the rally continues.

The team that scored serves for the next point. If the team that scored served in the previous point, the same player serves again. If the team that scored did not serve the previous point, the players of the team rotate their position on the court in a clockwise manner. The game continues, with the first team to score 25 points (and be two points ahead) awarded the set. 3 sets are played in one match.

Early soccer balls began as animal bladders that would easily fall apart if kicked too much. As time went on soccer balls developed to what they look like today. This was possible with the help of people like Charles Goodyear, who introduced rubber and his discoveries of vulcanization to the design of soccer balls. Today, soccer balls continue to be modified by scientist for the best performance possible.

History
Chives are the best team Soccer balls have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings.1 Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating soccer balls made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that soccer balls developed into what we believe a soccer ball looks like today.

Vulcanization
In 1838, Charles Goodyear introduced the use of rubber and his discoveries of Vulcanization, which dramatically improved the soccer ball. 2 Vulcanization is the treatment of rubber to give it certain qualities, for example strength, elasticity, and resistance to solvents. Vulcanization of rubber also helps the soccer ball resist moderate heat and cold. "The chemical process involves the formation of cross-linkages between the polymer chains of the rubber molecules." 3Vulcanization helped create inflatable bladders that pressurize the outer panel arrangement of the soccer ball. Charles Goodyear's innovation increased the bounce ability of the ball and made it easier to kick. Most of the balls of this time had tanned leather with eighteen sections stitched together. These were arranged in six panels of three strips each.4

Reasons to improve soccer ball
During the 1900, soccer balls were made out of rubber and leather which was perfect for bouncing and king the ball, however when heading, hitting the ball with the player's head, the soccer ball it was usually painful. This problem was most likely because of the water absorption of the leather if it rained during the game, causing head injury. Another problem that the early soccer balls had was that they deteriorated too soon. Because of the leather quality the soccer balls varied in thickness and in quality sometimes worsening during the soccer match.4

Ball Construction
Today, soccer balls are a little more complex than past soccer balls. Modern soccer balls consist of twelve regular pentagonal and twenty regular hexagons, positioned in a condensed icosahedrons spherical geometry.1 The inside of the soccer ball is made up of a latex bladder which enables the soccer ball to be pressurized. The ball panel pairs are stitched along the edge; this procedure can either be stitched manually or with a machine.

Present Developments of Soccer Ball
Elements of the soccer ball that today are tested are the deformation of the soccer ball when it is kicked or when the ball hits a surface. Two styles of soccer balls have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Southborough University; these two models are called the Basic FE model and the Developed FE model of the soccer ball. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilized isotropic material properties but included an additional stiffer stitching seam region. The result was that the Developed FE model resisted deformation more than the Basic FE model ensuring that the soccer ball will continue to develop even in the present, thanks to David Beckham who contributed to this project of the gravity controlling soccer ball. He is to receive a near 1 billion US$ if the project is successful.

Inflatable armbands (usually referred to as just "armbands"), are a device to help a wearer float in water and learn to swim.

Inflatable armbands are typically cylindrical inflatable plastic bands that are inflated and worn on the upper arm. When the wearer is in water, the air inside the armbands provides buoyancy on account of its far lower density than the water. Although often thought of as a child's flotation device, armbands are also available in adult sizes.

Although inflatable armbands are popular among small children, swimming experts caution against using them, because although water wings help the child to float, they do not prevent him/her from accidentally going under water and potentially drowning. Inflatable armbands are not a life-saving device. Mistaking them for one can create a potentially fatal false sense of security.

National safety standards such as BS EN 13138-3:2007 require inflatable armbands to confirm to certain standards, such as puncture resistance and the level of buoyancy retained after a period of time beyond the inflation valve being opened and left open (an assessment of the efficiency of non-return valves designed to prevent the armbands deflating suddenly if an inflation valve is opened). Standards also require prominent labeling near to the inflation valves to the effect that inflatable armbands are not life preservers and should only be used under competent supervision.

Inflatable armbands for swimmers were invented by Bernhard Markwitz in Hamburg, Germany. In 1956, Markwitz's three-year-old daughter had fallen into a goldfish pond and nearly drowned. Because of this, Markwitz invented and developed a swimming aid that would be safer for children than the swimming rings at the time, which were made of cork. A lottery win (253 thousand Deutsche Mark) gave him a suitable start capital. In 1964, Markwitz had developed the armbands in their final form and marketed them under the name "BEMA". Their modern name in German, literally translates as "swimming wings".

A similar design of water wings was shown in the magazine Modern Mechanix in October 1931. They were made of rubber, consisted of two parts and were worn on the upper arms. The armbands could be inflated through a valve. These were first demonstrated in public on the beaches of Los Angeles, California, USA.

In 1907, in response to swimming having become part of the school curriculum and therefore increased parental concerns about the safety of their children in the water, the Dean's Rag Book Company, London, introduced the Swimeesy Buoy, inflatable armbands with a colorful design in the form of a butterfly. (A plain white version was also available). This product became so popular that it was available, almost unchanged, until the outbreak of World War II.

Inflatable swimming pools are the contemporary pools which are easy to use and install they can be easily set up in your backyard for spending quality time. In summer you can stay cool and enjoy water games with it. Now the kids will love splashing around in the pool and having a blast playing with the water. It's a perfect way to beat the heat. A pool is an inflatable pool that can be easily installed. Some of the versions of pools require just one person. You just need to follow two simple steps in order to install them. Firstly inflate the top ring, and then secondly fill it with water. No separate tool is essential for setup of pool. You just require about half an hour to completely install them. Some larger Pools only require a pad to be place beneath the pool in order to soften the bottom. These inflatable pools provide very simple swimming pool alternative in comparison to ground swimming pools. Now your entire family can enjoy bathing and relaxing under the heat of sun. They prove to be complete refreshment for mind and other parts of body. These pools are available I various sizes depending upon your family requirement. Also no sand is required for supporting walls of pools. You can enjoy swimming in your backyard with the help of inflatable swimming pools.

In addition to being relatively easy to install a pool is relatively cheap. You have to spend just a few hundred dollars. The various factors such as on the size of the pool, power of the pump and addition options and structures influences the cost of pool. The more luxury it contains the more you have to pay.

Normally such swimming pools consist of a soft polymer. The ladders are generally made of stronger plastics. The pool can be very durable and it can be easily dissembled and packed in to compact size. These inflatable pools can be characterized as cost-effective and simple to use.

Majority of pool packages include the pools accessories. The entire package includes pump, filter cartridge, ground cloth, debris cover, ladder; deluxe maintenance kit and some even come with a volleyball or basketball game. Pool vices help to maintain the pool in order to ensure safety and hygiene. They help to absorb harmful chemicals out of pool water. A garden hose present at bottom aids in draining away water.

All the pools are sold with certain warranty period. Also in case you face any problem operating then well trained staff is available to guide you. They would reach to your address just after calling at our help line number. So it is highly recommended to buy swimming pools for maximum comfort and safety. You would certainly enjoy your summer with them.

Getting involved in hot air ballooning is as simple a process as following a hot air balloon and meeting it where it lands – yes that means it is indeed simple but it takes a lot of time, patience, courage and energy.

Ever heard of hot air balloon ride festivals?

If you are interested in hot air balloon, then you should probably go experience the thrill of a hot air balloon festival. Hot air balloon festivals are generally held in all countries all over the world, all year round. Not only do these festivals give the balloonists a chance to participate in the races while providing them with the opportunity to display their balloons, but it is also a great way of drawing crowds and allowing the public to witness this colorful spectacle while learning more about the sport.

There are hundreds of different hot air balloon ride festivals held every year, with the maximum number of them taking place in the months of summer and fall. If you are planning on visiting one of these festivals this year, then you should know like most hot air balloon festivals are like carnivals – from food and entertainment, to music and fun and all the frazzle dazzle that comes along with it – hot air balloon festivals are like the ‘Mardi Gras’ for balloonists, minus the samba dancers of course!

So, be prepared to wake up early in the morning because many flights take place in the wee hours of the morning, and I’m sure you wouldn’t want to miss that – would you? If you are interested in hot air ballooning – not just from a fun ride point of view – but you want to learn the ins and outs of the activity, then feel free to ask the pros questions. They’ll be more than willing to answer your questions, and if you are lucky enough, you’ll probably come across a balloonist that stays in your vicinity.

Getting Started with Hot Air Ballooning: Hot Air Balloon Ride Tips

No matter how you decide to get into the groove of hot air ballooning, you will surely fall in love with this sport. Its unique appeal makes it all the more attractive to adrenaline junkies of all ages. What’s more, it is one of the best conversation starters at a club, pub, coffee shop and even a PTA! It also makes a great first date for the young, a good outing for the families and an amazing travel adventure for the elderly.

So, when you are getting started with hot air ballooning, here are a few tips (no matter how inconsequential they may seem) to consider, as they will be of use to you:

? Here are a couple of items to carry along when you go on a hot balloon ride – warm jackets, camcorders, cameras, binoculars, camera batteries, and film.

? Search in the yellow pages or online for the best possible ballooning companies. Ask around for references and find the most popular ballooning area.

? Call in advance to book a flight. Prices vary from company to company. You might have to pay extra for chartering a flight and if you want special goodies like champagne and wine then you’ll need to customize your flight, which costs more.

? Shop around for different packages and deals. Most hot air balloon companies provide full-day and half-day trips.

? Be prepared to start off early – as most companies will ask you to come to the launch pad at dawn when the wind is mild or nonexistent. Bad weather conditions would mean your trip gets cancelled. After all, you don’t want to be involved in a hot air balloon crash do you?

? As silly as it may seem, most companies will advise you to use the restroom before you come in for your flight. Trust me; this is the most useful tip.

Hot Air Balloon Ride Precautions

? When ballooning, don’t get tensed about falling from the basket – it doesn’t really sway that much.

? If you are going to a popular ballooning destination, then book your ride in advance.

? Even though most hot air balloons tend to go where the wind takes them, make sure there is some ground crew following your particular balloon. But don’t worry about getting lost; the ground crew always keeps in touch with the pilot by radio.

? Even if you suffer from motion sickness, most people don’t get airsick when going on a hot air balloon ride. But if you are still concerned, then carry your motion sickness medication along.

? If you suffer from vertigo, then you may want to reconsider going for this activity. Yes, hot air ballooning is indeed addictive. Once you go for your first hot air balloon ride, you are definitely going to be hooked to the sport. You can say goodbye to sleep, boring weekends! Once you are hooked, you’ll want to go ballooning all the time.
