Japanese dentist Hideki Watanabe has invented a pot that stirs itself, thanks to
a series of ridges on its sides.

The product is being called Kuru-Kuru Nabe, or ³pot round and round.²

According to a roughly translated article on TV Tokyo, the grooves cause the
water to boil in such a way that creates a vortex. It also produces more even
and efficient heating, and less foaming means the pot is less likely to boil
over.
