## Why do ice rinks not melt?

The ice doesn’t melt because the rink is designed to stay cold enough so that such a thing does not happen. However, one particularly warm winter, I went to an outdoor ice rink and the ice did melt. There was still some ice to skate on, but everyone was pretty much wading through an inch of water as they skated.

## Do they paint the ice in hockey?

White powdered paint is mixed with water in a large tank creating a liquid paint mix. This paint is then applied to the ice surface with a large 12-foot spray boom and a pump. Two to three coats are applied to cover the surface. This is then sealed in with fine water spray, which freezes.

## Is hockey ice real ice?

Everybody knows that hockey is played on ice and ice is frozen water. But did you know that not all ice is the same? It turns out that the temperature and chemistry of the ice makes a big difference.

The standard for curling ice is to measure the air temperature and humidity at a height of 1.5m and aim to achieve 8ºC and 40% relative humidity (dew-point temperature of – 4.3ºC at 1.5m), with the ice- surface temperature at – 4.5ºC.

## Why is ice slippery if it is above F?

Recently it has been discovered that the outermost layer of ice is always made up of a thin ‘quasi liquid’. The topmost layer has no neighbours above it, and thus the water molecules can move more freely. The layer is extremely thin, only 10–20 nanometres thick, but it is enough to make the ice slippery.
