Underwater hockey.Like most strange sporting mutations, this game originated in England and celebrated its 60th anniversary last year. It was originally invented as a cure for boredom for diving club members during the winter break.One of the main charms of underwater hockey is the democratic nature of the equipment. All you need is a small stick, a one-and-a-half-kilogram puck, a glove, a mask with a snorkel and fins - this is much more budget-friendly than the expensive armor for big "ice" hockey.The popularity of underwater hockey is growing: men's world championships have been held for 44 years, women's for 30 years.
