Robotic cake with edible chocolate batteries created by scientists
Italian and Swiss researchers have created an edible robotic wedding cake. The 'RoboCake' features two edible dancing gummy bears, animated by an internal pneumatic system. The cake also uses chocolate-coated edible rechargeable batteries to light the candles. "The first flavour you get when you eat them (batteries) is dark chocolate, followed by a surprising tangy kick," a researcher said.
