Go to Post Engineering is a big, big type of fishing to teach. Inspiring kids to study it in college might be more practical. - connor.worley [more]

Re: Legalality of pnumatic ball launcher systems

I'm curious as to if you can depressurize an end of the cyllinder such that it's actually less than atmospheric pressure, theoretically achieving the same results but also technically within legality of all of the Q&A answers. Depressurisation would be achieved in a similar (but reversed) manner to what's described.
