Do you enjoy setting a bowl or plate twirling as long as possible, while at the same time irritating a swirl-sensitive sibling, parent or spouse? Then the innocent-looking bowl whirler is what you need for nearly perpetual pirouetting.
Encased in a Teflon pellet that glides in a ring-formed plastic
tube, an electromagnet and battery unit is propelled around the ring as a linear induction motor. Merely remove the film covering the adhesive, press the ring under the bowl and watch the wobbling fun. When the speed has been fine-tuned (60 to 200 rpm on the remote control), the rotating weight will keep the dish turning until it falls on the floor, the battery loses power or someone angrily picks it up.
Looking for more fun? Try the squealing, magnetic chalk that is magically pulled across the surface of a special blackboard in a screeching symphony while writing vulgar words in longhand.

||I do enjoy that. No longer do I
have to spin the bowl myself.
That's a fun noise. +
I once thought it was great fun to make irritating noises. I did this secretly, with my nose. That was in the first grade. I stopped when I was caught and publicly humiliated. I was caught because I didnt appreciate that the teacher, even though an idiot, had two huge swiveling ears, and could localize sounds like a rabbit.
||Here I thought I was the only one.
Trying to keep a wine glass twirling is a riot.
