Manganese (IV) Oxide Thermite

Project:
A simple and quick science project for our church kids

Difficulty Level (Easy, Medium, Hard, Insane):
Easy

Process:
Mixing 3g of fine aluminum powder with 24g of manganese (iv) oxide and lighting it on fire with a 4" piece of magnesium ribbon creates a very bright flash and a nice big cloud of smoke. Something I might mix up with the kids at church next science night.

I bought the manganese (iv) oxide and aluminum powder over 20 years ago when I first got into chemistry back in high school so I dug it out and it still works perfect. Maybe I'll try black powder next time...

Conclusion:
Awesome! I could totally have gotten into pyrotechnics...
