00:00100's of pipes are buried in the concrete floor below the ice rink
00:03They constantly pump an extremely cold liquid through them
00:07which keeps the ice frozen
00:08but once the season ends
00:10Warm liquid starts flowing through those same pipes instead
00:14Now the ice sheet begins melting from the bottom up
00:17Then machines break apart and scrape away the melting ice
00:21Until the entire rink disappears
00:23As they set up for the next event
