R-12 in a 2 liter bottle
We used to put r-12 in a 2 liter bottle , about 6 inches deep, and cap the bottle really tight. A 2 liter can holf lots of psi. We would toss them into cars that were unlocked, but with windows up. In the summer, it took about 10 minutes to blow up. Usually taking out several of the windows. Best part..... No evidence.
This also works in other confined areas,. i. e. Mailboxes
