In this video tutorial, Bre Pettis of Make Magazine makes a jam jar jet. A jam jar jet is basically a jet inside a jar. This project requires a drill, and of course a jelly jar. The smaller the whole, the more powerful the rocket. And don't forget the methyl alcohol for fuel, like gas line antifreeze (Heet or STP), Some of them even say "made with jet fuel." What better to use? Don't forget, fire is dangerous, so get out the safety glasses and be careful and enjoy your jet-like flames in a glass jar, way better than a birthday candle.
