The concept of water skiing can be expanded to skiing over almost any surface. We could even say there have arisen several offshoots that have taken water ski as its core derivative.
Take for example skiing over a water body while being pulled forward by an aircraft, instead of a boat. The same principle of water skiing is applicable in this format of skiing also.
The only difference is that the forward momentum is being provided by an aircraft. Another form of skiing is snowboarding. Snowboarding is rushing down a snow slope with feet attached to a board. This is a high speed sport and can be dangerous.
These days, kids take to trampoline like a fish takes to water. It is so natural for them to associate themselves with adventure sports that water skiing is not left far behind.
Adrenaline junkies have taken skiing to another level by tying a snowboard to their feet and jumping from an aircraft. This gives the enthusiast several minutes to perform acrobatics in the air before pulling the cord for the release of the parachute that would be tied to him so that he can land safely.
Slalom skiing is probably the toughest and finest of individual water ski activities. In slalom, the skier uses one ski instead of two to stay on water.
Mastering slalom is difficult and takes time as finding the balance over an unsteady substance like water while being pulled along by a high-speed boat can take lots of time. With its complicity comes the delight for the spectators.
