But an unnamed Japanese inventor has been prototyping pots with Bundt-pan-like fluting in the sides, angled in the manner of a helical gear. The reason? When heated up, convection causes the liquids within to move (hot water rises to the top), and the vortex shape channels that movement into a fixed direction. The result is a pot that essentially stirs itself!
Älskar när någon tänker ett varv till runt något som alla andra tar för givet.
