Well TX, I am using a light controller like this ...

For these kinds of props I want them on a controller that I can hit when I want it to pop.. This way I choose who gets to wet there pants.. muaHAHAHAH..

These props are on pneumatic cylinders and would be hooked up like this..
Air compressor to powered valve then to prop. The powered valves I use are 210 controlled so I can just plug them right into this controller.
Works well and has 8 plug ins and I have two of these units so I can control up to 16 things from them...
