Physics Experiments: Viscous roll

Caution: this is not a dessert, but ping-pong balls dumped in honey. Yes, we had to shop for a lot of honey yesterday to let Simon do the trick. It’s about a bottle rolling down a slope and stopping on the way, and rolling again. The viscous honey makes the balls super slow, this us why the bottle has uneven/unstable weight on each side. We didn’t quite succeed. The bottle did stop, but did not quite resume its motion down the slope. On other occasions it did roll well, but didn’t stop. We also tried a different bottle and a longer slope (ironing board). Perhaps, the slope still wasn’t long enough or the balls needed even more space inside the bottle?

Inspired by a Veritasium video.
