Couldn't a digital clock powered by a battery to substitute the chord and the speaker wires atached in the spray exit part and will explode like as if a detenator was atached to a explosive when the clock goes to a certain time and the speaker is supposed to beep but instead explodes the spray bottle?If so I would suguest using an old digital clock so not wasting money.

wtf, where did you hear that shit, oxygen burns colourless. The orange in a flame is usually caused by soot.

Well oxygen doesn't actually burn. It allows a fuel to burn.

fuck it, i dont feel like getting into this again....piss off...(not you, firetime, anyone who argues with you)

Yeah i remember having this arguement once before

yeah, you're right, I said it wrong, but that's a detail.

im not sure if it burns colorless. but i think pure oxygen burns. not sure but isn't that what they use for spaceships as fuel

ha i was just reading on how to do this. you need some match heads and a bb gun. tape a shitload of match heads onto the concave part of the can (close together) and then shoot it with a bb gun. the bb hits a match head, creating a spark, and at about the same time the propellant comes out and (hopefully) catches flame. shoots like a motherfucking rocket. tell me how it goes
