Thermite is a mixture of Aluminium and Iron Oxide (rust) that when
heated to the correct temperature, ignites and burns at several thousand
degrees. (4 or 5 or 6000 or something).
The ignition temperature is about 6 or 7 or 800 degrees and can't be lit
without the help of a chemical reaction.
This is where Magnesium comes into it.
Magnesium can be lit fairly easily and burns around the 6 or 7 or 800
degrees that the thermite needed, to ignite.
Ignited thermite will take about half a second to reach a couple
thousand degrees, which I would say, would really mess a spectator up bad.
(Probably get a huge radiation burn or something).
This stuff can burn underwater and I am fairly sure it is used for
underwater welding, etc.
DO NOT ATTEMPT TO MAKE THE STUFF.
..seriously.
