The recoil will not be nearly this large, unless you're tossing chain mail t-shirts. The 50 psi air will be rushing through a 3/4" or 1" solenoid valve and quickly expanding to push on a half pound projectile over 7 square inches of area. My back-of-the-envelope calculations based on how far a half-pound T-shirt is tossed tells me that the recoil force for our no-sabot system (we roll the shirts into their own sleeves and muzzle load them) is more like 40 pounds than 350 pounds. If you are feeding the shirts in cylinders, you may require more pressure and will generate more recoil.

Not a bit surprising after the teaser video; I made a bit of chain mail myself in the 80's. I'm rather impressed with how much our student leadership team is focussing on game mechanics, strategy, and grand strategy while ignoring the stylistic hints we've been given. I wish I could ignore teasers and game hints as well as they can.
