Snow tubing

Tubing (also known as inner tubing, "bumper tubing" or even toobing) is a recreational activity where an individual rides on top of an inner tube, either on water, snow, or through the air. The tubes themselves are also known as "donuts" or "biscuits" due to their shape.

Tubing on water generally consists of two forms: towed and free-floating, also known as river tubing. According to Time Magazine, tubing was purportedly invented in Thailand by Princess Chumbhot of Nagar Svarga sometime in the middle of the 20th century, but examples of the practice were published as early as 1916, when the popularization of the automobile meant a large supply of rubber inner tubes was available to the general public.

Towed tubing usually takes place on a large body of water such as a lake or river. One or more tube riders (often called "tubers") tether their tubes to a powered watercraft such as a motor boat or a personal watercraft. The riders are then towed through the water by the watercraft.

In free-floating tubing, the tube riders are untethered and often conveyed by the current of a waterway. Tubers paddle with their hands and often used webbed gloves to steer. Tubes can be outfitted with tube covers or 'skins'. These covers are fabric, and cover the bottom of the tube, the sides, and have a skirt that covers the inner diameter, while leaving room for the tuber to sit. Covers can be altered with pockets, can holders and have handles for the tuber to hold on to. It is strongly discouraged to tie anything to the tube or use ropes of any kind as a tuber can get bound or wrapped in them and potentially drown. The Esopus Creek in the Catskill Mountains, New York is a common place for tubing, starting in Phoenicia and proceeding eastward. As in all watersports tubers should wear appropriate safety gear such as life vests, protective water shoes and helmets. Whitewater tubing can be fun and exhilarating, the size of the tube allows a tuber to ride the river in an unencumbered manner not found in rafting or kayaking. Tubers can employ the use of such items as dry boxes and mesh bags to carry small personal items and pack out trash, cans and bottles from their trip.
