#18. Jai Alai

In Spain, people have a very peculiar way of practicing squash. Jai Alai or “Cesta-Punta” is a sport that involves throwing a ball against a wall using a basket carved in wood. The thrower must throw the ball as fast as he can to avoid a member of the opposing to catch it. If you find the sport boring, think again. The ball can reach speeds above 300 km/h, and an impact at that speed can put you in the hospital for several months.
