Suction ?????
 

Hey I was wondering ? It is legal to use some sort of suction device. For example use a piston to produce suction then that same piston to remove suction ?

From FIRST Q&A:

Q: It is it legal to make a mechanical device like a syringe to evacuate air out of an area so as to create a vacuum, thereby taking advantage of atmospheric pressure when attaching to balls?
A: Yes, it is legal.

Not sure this is exactly what you were looking for but yes you can use a pnuematic piston to create a vacuum.

One team at the Chatsworth Scrimmage used suction to pick up the balls, it worked out great. It was very cool.
