(It didn't.) Right Door (top to bottom): Icarus, the Greek mythological figure who tried to fly from Crete by attaching feathers to his arms with wax. He fell when he flew too close to the
Ski wax crayon, applying a liquid wax or a spray wax. Hot applications of wax include the use of heat from an iron, infrared lamp, or a "hot box" oven. The role of glide wax is to adapt and improve the friction properties of a ski base to the expected snow properties to be encountered on a spectrum from cold crystalline snow to saturated granular snow. Modern ski bases often are made from ultra-high-molecular-weight polyethylene (UHMWPE). Kuzmin asserts that UHMWPE is non-porous and can hold neither wax nor water, so there is no possibility for filling pores; furthermore, he asserts that UHMWPE
