Thermite Balls

if you smack two heavy metal balls together the energy of their Collision will be focused at such a small Point enough heat can be produced to literally burn a hole through paper try this at home it smells like smoke but let's make it even hotter first I'll need to rust up one of these balls a bowl of water should do the trick ten days later that's a rusty meatball we'll wrap the other ball in aluminum foil turn down the lights put on some ear and eye protection and start whacking until this happens did you see

that that is molten slag at more than 4 500 degrees Fahrenheit now that didn't happen because I'm so strong even though I am it happened because the colliding balls produced the ignition temperature needed for a thermite reaction the aluminum reduced the iron oxide the rust on the ball to form aluminum oxide Elemental iron and much more heat than I put in now that's what I call exothermic redox
