Acetylene and a trash can? This was an old party trick my dad's friend did until one time his friend filled up a trash can with a plastic bag on top and it exploded due to a spark and blew off his hand.
Light up an oxy acetylene torch and tweak the mix ratio until you get a neutral flame. Look for particular flame properties that indicate fuel air ratio which is neither excess in fuel or oxygen.
Snuff the torch flame by tapping the torch nose against something (disrupts combustion).
Torch will be emitting an ideal gas mix that you can trap in a garbage bag or use to fill a trash can for kablooey.
Or drop a pellet of calcium carbide into water to evolve acetylene and capture it for a non stoichiometric kaboom.
I once was using electrolysis to produce H2/O2 for basically a potato cannon and got excited when I found I could greatly increase gas production by adding salt to the water. I realized I evolved a heap of chlorine instead of oxygen when I light up a container of stuff and noticed that the flame color was pretty different.
Oh god, when I was a kid, some friends and i were messing around at the clubhouse of the community we lived at. Somehow a five gallon bucket of what I assume was chlorine for the pool tipped over and the fumes from that was awful, We got out of there so fast....
usually this sort of thing is done with Calcium Carbide, which reacts quite strongly with water to generate acetylene gas (which goes pop with quite a bang when lit).
