Well most people need to have snow year round to do their sport of choice. Well the SnowTunnel is here to help, well only if you are in Dubai's lavish indoor ski slopes in the middle of the desert. The Snowtunnel is a fairly simple device mechanically - a corrugated steel drum that has refrigerant piped through it to cool the metal. When water is sprayed on the drum's interior, it quickly freezes. Then, a rider hops inside on a snowboard and sets the drum rotating at a speed they're comfortable with, catching an edge on the iced-over metal and riding it like a cross between a snowboarder and a tube-riding surfer.
