make it with a union and have a chamber filled with dry ice and water that when thrown the dry ice would hit the water and create enough pressure to blow?
It would work, all you would need is a system that would only allow the 2 to be mixed after being thrown.
Maybe a ball valve?
That sounds like a good idea. You could also do something like a qev piloted by a pop off valve.
