I'm making a pnuematic potato cannon and I need help on what is the best piston release method? Answered

I know of two ways, but am looking for advice from veterans. I am not a novice at this, and cost is not a problem, so give all and any ideas. (illogical ones are accepted!)

Use a .5" disk of deldrin. encircle that with a plasma generator. Now on firing the plasma generator vaporizes the disk in 2 microseconds thereby releasing all of the pressure instantly. Or you could just use a big globe valve with a long handle.
