Description

Pimp your cannon with a vacuum gauge.

This ⅛” BSPT (taper) male threaded pressure gauge makes your cannon look way cooler. It also makes it easier to know if you have a crack in your vacuum seal and provides interesting information about how fast the vacuum forms. Is it exponential? That would be an interesting twist on the cannon experiment.
