Burning steel
Steel can burn. It can be used as fuel. But there is a problem. It will only catch fire if it is first heated white hot. It takes a lot of energy to heat a big piece of steel white hot. Normal fires are not hot enough to do this. It is easier to heat up tiny bits of steel until they catch fire. This happens often when a power grinder is grinding some steel. We see sparks fly. These are not electric sparks. Instead they are tiny bits of steel which have become white hot and are burning. Have you ever used flint and steel to start a fire? Same thing. Tiny bits of metal get heated white hot, and they catch fire. When the steel wool touches the 9-volt battery terminals, the battery forcefully pumps the electron-liquid within the steel. There is an electric flow inside the thin steel wires, and they heat up. They grow white hot and catch fire, and the steel wool burns. This is an excellent way to start a campfire if you have no matches. But remember, it drains energy from your 9-volt battery, and you can only start a few fires before the battery stops working. Better learn fire-starting with a "friction bow" or "fire drill." There might not be any batteries for sale in the middle of the woods! http://www.madsci.org/posts/archives...2488.Ch.r.html http://www.elmhurst.edu/~chm/vchembook/143Afeoxide.html |

in that video it didn't look like he was using a 9 volt, i knew you could do it with that, i thought there might have been something more to what that kid did. I really want to do that now!
