In this video I discuss the science of sparks and how to make a "spark thrower" which is a leaf blower that has been rigged to throw 1400°C sparks. I use fine steel wool and a lot of blowing air to oxidize the iron to form iron oxide.

If you want to try to make this, the steel wool that I used was size 0000 steel wool and any metal whisk. Don't wear flammable clothing or do this in a dry area!
