From The UberReview: Self Stirring Pot is Ridiculously Simple

The Kuru-Kuru Nabe is a self-stirring pot that was invented by a Japanese dentist who goes by the name of Hideki Watanabe.

Watanabe created his initial prototype by using dental plaster to coat the insides of the pot so that it creates a natural whirlpool when boiled – simple and effective.

I find it interesting that a lot of people have translated “kuru-kuru” to “round and round” – my preferred translation would be “spinning”.
