Ok, I found this article made by Dave Barry and thought it was pretty funny and amazing, I'm not taking credit for this tutorial
1] Get a cheap toaster from say Wal-Mart

2] Go buy a box of poptarts

3] Beware! Hold down the toaster's handle with a stick or something
4] After a while you should see flames coming out
