Thermite Reaction

An exciting chemical reaction where all you need is aluminum foil and rusted ball bearings.

A rusted iron ball bearing seems like it might be past its prime, as far as uses go. Thankfully, all you need to do is wrap one of the bearings in some aluminum foil. You’re almost ready to create a thermite reaction. BANG!

Materials

  • Rusted, iron/steel ball bearings
  • Aluminum foil
  • Adult supervision
