Spinning nut inside balloon - GIF

[WmRMeyers]

Ah, I was waiting for the hex nut to fatigue the balloon and become a dangerous projectile. I am sure if I TRIED this, I would be explaining to the emergency room staff that - yes I really do have too much free time on my hands.

Been thinking about that myself. Only thing saving me is that I'd have to go out and buy some balloons. It's too hot out there! Ain't going! Maybe later, though...
