What is underneath an ice rink?
The entire rink sits on a base layer of gravel and sand (G) which has a groundwater drain at the bottom. To defrost the skating surface, the
brinewater
is heated and pumped through the ice-bearing concrete slab. This heats the under layer of the ice, making it easier to break up and remove with front-end loaders.
How do they make ice for hockey rinks?
The most common method of refrigeration used in keeping an ice rink frozen is
an indirect refrigeration system
. This is where a liquid refrigerant (often ammonia) absorbs heat from a secondary liquid (often brine) which has absorbed heat from the source.
Why do ice rinks not melt?
The Zamboni scrapes the ice surface and collects the snow. The machine also puts down a thin layer of heated water. The water is warmed to about 140-145 degrees. It doesn’t melt the ice
because it freezes pretty quickly
.
How cold do they keep ice skating rinks?
Most ice rinks will keep the air temperature at a brisk 55-65 degrees and the
on-ice temperature between 17 and 29 degrees
.
Does a Zamboni use hot water?
The machine
dispenses warm water
(140 to 145 degrees F or 60 to 63 degrees C) through holes at the back, where a towel smoothes it as it freezes along the surface [sources: Exploratorium, Zamboni].
How do ice rinks keep ice frozen?
How does an ice rink stay frozen? The most common method of refrigeration used in keeping an ice rink frozen is
an indirect refrigeration system
. This is where a liquid refrigerant (often ammonia) absorbs heat from a secondary liquid (often brine) which has absorbed heat from the source.
How do zambonis not slide?
The tires have studs to keep the Zamboni from
sliding helplessly around the ice

Can you skate on melting ice?
Simply put:
Skaters can’t exert enough pressure to melt the ice
. “So while the basic idea is correct — you can melt ice by pressurizing it — the numbers don’t work out at all,” Limmer says. (One paper explains if the ice is a very cold -4°F, it would take a pressure of 39,680 psi to melt enough to allow for skating.
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.
Can you wear ripped jeans ice skating?
People make a mistake by wearing jeans to an ice rink. It isn’t impossible to skate while wearing jeans, but since falls are highly likely, you want something that will dry quickly. Also, you want something that will not constrict your legs, so you can move more easily.

Why do Zamboni’s use hot water?
The heated water, according to Tharaldson, is about 140 to 145 degrees Fahrenheit (60-63 centigrade); “the hotter the water,” he says, “the more even a
surface you’ll get–it melts that top layer when you cut across
[the ice].” Click the “forward” button below to continue.
