This might be considered off-topic, but thought it was worth asking, as I have no idea where else to ask --
I'm trying to make something forcibly eject from a cake. I've done some testing with a can of reddi whip, and I've found that I can get decent distance by restricting the size of the opening. But I'm debating on getting my own whipper, thinking that I can then tint the results, but that I might also be able to charge it more than once to get a more forceful ejection.
Are there any problems with over-charging a canister? In the response to the question about ragged peaks from a whipped cream dispenser, one of the responses said it might be from over-charging the container, so I'm a little concerned. (not that much, as it just needs to shoot out, being pretty isn't necessary, so ragged peaks aren't an issue; the whole thing turning to butter and clogging the canister or being inedible would be)
(I also assume there's a safety margin so it's not an explosion issue if I only double or triple charge it... I seem to remember my mom once double-charging one, when it didn't dispense, only to find out she had clogged it up with home-grated nutmeg; there wasn't an explosion 'til she tried taking the lid off)
