here it is i stake it in the and the skull pops up

It is my first venture into pneumatics and it was a hack lol

How does it work?

I took out the screw that controls how fast it moves put in some fittings took out the piston made it air tight and now all i do is put air into the fittings and wah la

Oh, so you have to connect it like any other pneumatic prop. For a second I thought you had made a self contained pneumatic prop.

no it still get hooked up to the air compressor but i have ideas for an air tank for it next year so all i do is fill up the tank every-once and a while and trigger it when ever
