How many y'all got to see @Dean, @Leadhoof, @eugenfrankenfurter, and @bluebioballs all in the same day?

Drill a hole in the cap of a 2 liter plastic bottle. Insert valve stem. Pump up to about 120psi. Shoot. You'll get a nice deafening boom.
Not sure about the pressure needed. Proceed at your own risk.
Same reason I'm selling the tannerite. No place to shoot
