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. www.hammacher.com
