Jun 12, 2011 - For use of thermite in cutting steel, see my video "Incendiary Experiments".The mythbusters guys set off 1000 pounds of thermite to try to cut a car in half, and explosives experts at New Mexico Tech try to cut a column and a beam, and a Florida Engineer, Jonathan Cole, cuts columns, beams, bolt heads, and bolts.

Mar 8, 2012 - the common ratio that i've heard is good is 2 to 1: iron oxide to aluminum powder. all i know is that you need more iron oxide than aluminum powder.play around with it and see which ratio works for you :)
