We need more innovation and design for ordinary tools and accessories. Otherwise, we haven't made much progress from the days of the caveman. The device shown is a battery operated self-stirring coffee mug. It spins at 3,000 rpms, which is faster than you... so it probably works.
"A favorite gift among our customers, this mug has a miniature battery-operated propeller at the bottom of the well that spins at 3,000 rpms at the touch of a button on the handle, automatically stirring your beverage and eliminating the need to dispose of stirrers or find a place to leave coffee-dampened spoons. At your command the propeller re-stirs mugs of hot chocolate, coffee, or tea, preventing chocolate or sugar from settling out of solution, and overcoming the traditional challenge of adequately mixing honey in a hot drink. The mug includes a lid to keep contents from spilling and to retain heat, and the lid can be placed underneath the mugs base as an impromptu coaster. The mug is lightweight injection-molded plastic sheathed in a stainless steel exterior. Requires two AA batteries. Set of two. (9 oz.)" - Hammacher Schlemmer
