edit: Their 'first test' video seems to be shooting them closer to 100yards, hard to tell. 150 yards does seem like a stretch with that valve unless they can push the pressure above 150PSI (which doesn't seem likely if their reg only goes as high as 150PSI) and/or increase the valve dwell time.


I looked up the dimensions of a basketball court. My 70 foot guess was a little high. They are launching from near center court and going 1/2 court to the wall. The distance is about 50 feet. The outdoor range looks to be a little farther, but I'm sure it is less than 150 Feet.

My Marshmallow Cannon tosses shirts 200 feet at 100 PSI. That is without a valve with a low CV and hose between the valve and barrel.

The point of my previous post was no to second guess your range judgement but to add that they probably regged the pressure down in the cannon and/or changed the dwell time of the valve so they would not over-shoot the basketball court.

Without knowing the dwell time of the valve and the pressure the cannon is regulated to for a particular shot, it would be difficult to estimate accurate range distances at the cannon's full potential.
