What does a used can of soup, old PC speaker, and propane equal ? A "Pyro Jam Can" of course! Inspired by a Rubens tube that I built the "Pyro Jam Can" is flame spitting candle that likes to jam to the rhythm of the beat. Finished eating your soup and ready get building? Lets light this can so you can jam out!

!!!!!!!!!WORD OF CAUTION!!!!!!!!!!!
YOU BUILD THIS AT YOUR OWN RISK. BE SAFE. KEEP A FIRE EXTINGUISHER NEAR BY. HAVE A FRIEND NEAR BY TO ASSIST IF THINGS GET OUT OF CONTROL. ONLY USE IN A WELL VENTILATED AREA WITH NOTHING CLOSE BY.
BE SURE TO TRIPLE CHECK FOR ANY LEAKS. NOT CHECKING FOR LEAKS COULD CAUSE A GAS POCKET THAT WILL IGNITE! TURN GAS OFF IMMEDIATELY IF FLAME BURNS OUT AND WAIT FOR ROOM TO CLEAR OUT BEFORE REIGNITING.

OK, now on to the build ;-)

Great instructable. What would happen if you put a subwoofer instead? The membrane will shake a whole lot more, won't that blow out the flame?

That's awesome. I have propane, cans, and spare speakers, so I could definitely make this. My only problem is that my speakers are just cones... can I get this to work without any amps?

Thanks! Sorry for the delayed response. Don't think your going to get much response with an amp. You can find one in an old PC speaker or build one like this http://www.reprise.com/host/circuits/lm386.asp using available parts from Radio Shack.

Be careful,

Ha, I think I'll just find some old speakers :P Thanks for the schematic though.

Typo "Don't think your going to get much response "without" an amp. But I think you know what I meant. ;-)
This is really cool! I will have to have a go at it! Nice instructions, too. Thanks!

Thanks! Its a relatively simple build. Everything just screws and drops in place. Id love to see some video and pictures when you build it.
