I know, I know... your grill is the cherished hearth-o-barbeque, but if you happen to have an old grill or a friend who has a grill but doesn't cook... or if you are a diehard pyro, you can make your own glass!

How does this work? Well, you can't make just any glass in your grill. It needs to be glass that has a relatively low melting point, such as soda lime glass. This is glass made from grinding silicon dioxide (sand) with borax, washing soda or lime. You're still going to need about 2000°F to make the glass, but if the ancients could do it, so can you. They would have used a fire with a bellows, but you can use a charcoal fire that is fed air using a vacuum cleaner.

If you want to try this project, you can get details and watch the video of home glassmaking in action at Popular Science's website, Definitely watch the video. It's a spectacular demonstration, plus you'll see why most people will choose to use their grill for steaks rather than making glass. FIRE!
