Consider the ice cream cone: one of the great green inventions, a form of packaging and transport that leaves no trace, no waste. Then consider what inventor Richard B. Hartman has wrought: a battery powered plastic ice cream cone, for those people incapable of turning their cone by hand. Seriously, it takes real genius to turn edible packaging into plastic and battery garbage.
Patent 5971829 describes it as an
"eating receptacle for supporting, rotating and sculpting a portion of ice cream or similarly malleable food while it is being consumed comprising: a hand-held housing, a cup rotatably supported by the hand-held housing and adapted to receive and contain a portion of ice cream or food product of similar consistency, and a drive mechanism in the hand-held housing for imparting rotation upon the cup and rotationally feeding its contents against a person's outstretched tongue."
Stupid.com, where it is appropriately sold, defines it more simply:
No more turning your cone to lick the next melting corner! Now the Motorized Ice Cream Cone Holder does it for you!
I know, this was a serious problem, but imagine if such ingenuity was applied to, say, cold fusion. Found on the Red Ferret
