Yes, cause this hobby isn't hazardous to your physical well being

That's awesome! They got so many varying effects. Also, the water (I'm assuming that's what it was) in the frying pan for coolant looked so ineffective in the ending videos. That would suck if the glass exploded right in your face. They could have just cut a gallon milk jug in half and submersed the jar fully in water exept for the very top, which would have to be taped on the sides of the lid to make sure it wouldn't float (or would it even float?) This would also protect against glass shrapnel if it ever did get hot enough to explode. What was the thing they threw on the top of the jar to light it right around the 42 second mark?

Edit: Or it would just be safer to do this way but you don't get the cool effects of seeing the flame:

OMG!!!!! I just tried this for 2 hours!!! I used a glass jar, a tin can and even a plastic cup! Nothing yielded results. I tried every flammable I could get my hands on except gasoline including but not limited to nail polish remover (the closest thing to denatured alcohol), tiki torch fluid, Primeflo silicone lube (this is really flammable, much more than WD40), and antifreeze (what the videos recommended). I can't think of any others. Nothing worked! I hope to try it again following one of the videos instructions exactly. I want to replicate the video I posted before.

Edit: Maybe I should have tried gasoline: http://www.youtube.com/watch?v=e3R9hStCHAg

I plan to get some heet antifreeze to try it with. I think my problem was that I cut the hole too big.

Be careful, and let us know if it works.

We used to do a similar trick w/ denatured alcohol and a big Sparklets water bottle! Don't try it kids! -Glenn
