In this video I build a jack-o-lantern that can breathe fire! Unfortunately I don't feel this project is safe enough to actually put outside for Halloween, but it was a fun experiment nonetheless!  Maybe a better trigger mechanism and better safety features could make this project safer.
Pretty awesome project even if you couldn't really display it. : )
Thank you! I'm sure there's a way to make it a bit safer but it's a risk no matter what.
