I am entering the fray.
Have a design and all, but I will be needing power... We have a generator? Or is there power at the park?
Ok, if all else fails, I can hand pump. But it will take... A while, to fire
I just need to power an air pump. Need 120psi to push a potato soo fast that when I remove it from the flight container, It will have become a vodka martini
Shaken, not stirred
