There is a spectacular video of how fast a thermite reaction can melt
through blocks of ice at www.mythbusters-thermite.notlong.com

Two clips showing the burning of different mixes of thermite and several

They must know that, the more they say 'don't try this at home', the
more inclined people will be to do exactly that...
