Making a Sword with THERMITE!

  • Usually Thermite is used to destroy things... Instead, I wanted to use it to make something to destroy things with.
    If you have never heard of it -Thermite is a mixture of Iron Oxide (rust) and Aluminum powder. When you ignite it a vigorous chemical reaction takes place which results in liquid iron. Its used industrially for welding metal, the military uses it to destroy enemy equipment, teachers use it for science demonstrations, and youtubers just melt stuff with it.
    I made a mold out of insulating firebricks, and set off the thermite over it to fill it with molten steel!

    maybe look into using flux. I believe calcium fluoride is a good one to use. Look up "The Gayest Person on TVclip" he has some pretty interesting thermite videos.

    When you mix fuel, metal oxide and metal powder in just the right way, it burns at two thousand degrees Celsius. Hot enough to cut through nearly any barrier known to man. Throw some C4 into the mix…and you’ve got one hell of a combination.
