Hockey takes advantage of one of the most precious liquids in the universe, water. Water is used as ice in it’s solid form. A hockey rink is 200 feet in length and 85 fee wide, therefore takes around 10,600 gallons of water to fill to about an inch. However, water expands when solidified, thats why some pipes break. This is how zamboni’s play a huge roll in the process of maintaining ice. It first removes first layer of ice, then puts new coat of water after finished. Therefore removing solids/refurnish ice before next period. This will be helpful when looking at the rink and it’s design. An amazing source of information!
