Use the links below to show a thermite reaction. There are several amateur videos of the thermite reaction on the web and YouTube. The following are from other Universities.

The thermite reaction is so exothermic that it isn’t safe to perform in a classroom. In this reaction iron oxide is reduced by aluminum metal to produce iron metal and aluminum oxide. The reaction is given below.
Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s)
So much energy is evolved as heat that the iron produced is molten. It spews from the reaction vessel and melts through it.
