Making a Sword with THERMITE!

  • Added:  5 days ago
  • 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!

    Instead of dipping the hot metal into water you should try dipping it into I think oil. It will make a better blade and there won’t be as many cracks or air bubbles

    Honestly I love your videos where you just put random molten stuff in water, or you mix two things that you'd never see before, like liquid nitrogen and canned air.

    Did you use oil in the fist tank or, like I suspect, water? If you used water then that sword is gonna have stress cracks in it and it's not safe for use

    You should try to make a Battlefield Illumination Shell with the Magnesium ;)
    Take a Cardboard Roll and put a Sparkler Stick inside...then you take Magnesium Dust,add a bit of Arab Gum,spray some water on it and then you stuff it into the Cardboard Roll around the Sparkler Stick.
    It makes not much sense "for Fun"... cause it just makes you blind when you look into... but it would be cool for a Video to see how much would be visible in darkness :)

    Doing a thermite casting in shorts and no face protection whatsoever. I couldn't believe he just dumped that fuel tank/torch right next to the lit thermite. I wonder how long it'll be before he ends up in the hospital.
    On the up side the idea of mixing in the steel shot seems like a good idea. I wonder what sort of mechanical properties the casting has.
    I seen the jar labeled "magnesium" early in the video. Was the thermite made with magnesium instead of aluminium?
