How do they make the ice and how do they layer it and how to they keep it cold and hard.?

Question

on ice rinks

Answer 1

They pour water in a very shallow "tank", they put coils containing antifreeze in the water and connect to a very large "refrigerator" that pumps supercooled antifreeze solution in there.  They don't use water in the pipes because it would freeze also.

For "portable" rinks (e.g., Ice Capades) they have huge trucks outside that have enormous refrigerators on them.  After the last show, they break the ice up (usually) and let it melt.

Answer 2

You are too cute!

There are water pipes that fill up the rink.  Then there are coils that freeze the ice right where it stands.
