Who else made this in high school? Our is this just a country thing. Just give me an empty 10 gallon bucket, an empty 2L, tin foil, and some good ol’ earthy nuggets and I’ll mcgyver you a gravitron.
You have never made one like this.
The first affordable all-glass gravity smoking system ever made.
The Gravitron is the most efficient smoking device on the market.
No smoke is lost because it is contained within the inner chamber and consumed without leaking.
