My former downstairs neighbor wanted me to order gender reveal balloons for her, as she didn’t know how to order stuff on the internet. They were black, and you ordered ones with a pink or a blue card inside. Seemed inane to me.
Sounds insane to me too but better than homemade explosives.
Whatever happened to carbide cannons? I’m pretty sure they were safe and made a big boom. In the ‘60s they were advertised in comic books IIRC.
