Hmmm... I was thinking the same until Monday afternoon. Now as I throw this out there I get the feeling that I may recieve some flak about not reading the manual, but I would like to ask, "Is this legal?"

What we did was take a 2" bore, 2' (about ish) stroke cylinder and cover up the air port nearest the piston, then we pressurized the other side to 60 psi. The piston extended out about 16" and stopped. We then removed the cover (thumb) from piston side port and the piston shot out with a resounding CLANG!!!! (In otherwords a GREAT deal of force.)

But the reason why our mentors questioned the legality is the little FIRST rule that states that, you cannot compress air in "non-Clippard" containers. I have asked an alum, and have yet to hear back. Now I'm curious as to what the FIRST community has to say.
