This was a very small show, set in an intimate arena theatre setting. The set consisted of a single wall of a homey kitchen.
So, I devised a system that used an enclosed water reservoir. Air pressure is fed in from the top of the tank, which would force the water downward, instead of just relying on gravity. This turned out to work quite well.
It was a simple enough rig, and it turned out really well, so I was quite happy about it.
