I am once again defeated
In 2026? 2026? Do we have a c/angryupvote yet?
When I discovered this in high school we called it a jam jar jet. We used isopropyl alcohol for the fuel.
Bahahaha you fucking piece of shit, I love you
You son of a bitch!
Anybody actually know how to do this?
Ha! You motherfucker. Glorious.
PSA: Do this with plastic jugs to reduce the risk of broken glass in your eye.
