Parachuting

Parachuting, also known as skydiving, is the action of performing acrobatics during freefall, followed by deployment of a parachute. It is performed as a recreational activity and a competitive sport.
A typical jump involves individuals jumping out of an aircraft (usually an airplane, but sometimes a helicopter or even the gondola of a balloon), at approximately 4,000 meters (around 13,000 feet) altitude, and free-falling for a period of time (about a minute)[1] before activating a parachute to slow the landing down to safe speeds (about 5 to 7 minutes).

When the parachute opens (usually the parachute will be fully inflated by 800 meters or 2,600 feet) the jumper can control the direction and speed with toggles on the end of steering lines attached to the trailing edge of the parachute, and can aim for the landing site and come to a relatively gentle stop. All modern sport parachutes are self-inflating "ram-air" wings that provide control of speed and direction similar to the related paragliders. Purists in either sport would note that paragliders have much greater lift and range, but that parachutes are designed to absorb the stresses of deployment at terminal velocity.

Skateboarding

Skateboarding is the act of riding and performing tricks using a skateboard. A person who skateboards is most often referred to as a skateboarder, or colloquially within the skateboarding community, a skater.

Skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2002 report by American Sports Data found that there were 18.5 million skateboarders in the world. 85 percent of skateboarders polled who had used a board in the last year were under the age of 18, and 74 percent were male. Freestyle skateboarder Rodney Mullen was the first to take it to flat ground and later invented the kickflip and its variations.

Bungee Jumping

Is an activity that involves jumping from a tall structure connected to a large elastic cord. The tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object, such as a hot-air-balloon or helicopter, that has the ability to hover above the ground. The thrill comes as much from the free-falling as from the rebounds.

When the person jumps, the cord stretches and the jumper flies upwards again as the cord snaps back, and continues to oscillate up and down until all the energy is dissipated.

Kayaking

Kayaking is the use of a kayak for moving across water. Kayaking and Canoeing are also known as Paddling.

Kayaking is generally differentiated from canoeing by the sitting position of the paddler and the number of blades on the paddle.

A kayak is as a boat where the paddler faces forward, legs in front, using a double bladed paddle. Almost all kayaks have closed decks, although there are many sit-on-top kayaks which are growing in popularity, as well as inflatable kayaks which come without decks but which have air chambers surrounding the boat.
A canoe is defined as a boat where the paddler faces forward and sits or kneels in the boat, using a single bladed paddle

Rafting

Rafting is a challenging recreational outdoor activity using an inflatable raft to navigagate a river or other bodies of water.This is usually done on white water or differnet degrees of rough water in order to thrill and excite the raft passengers.

Windsurfing

Windsurfing is a surface water sport that combines elements of surfing and sailing.

It consist of a board usually two four meters long, powered by effect of the wind
on a sail.The rig is connected to the board by free-rotating universal joint and comprises a mast, wishbone boom and sail.
