Here’s a small high-tech device that emits ulstrasonic vibrations to freshen up your beer’s head.
Using ultrasonic vibrations, the Sonic Foamer excites the gases in your beer for an amazingly creamy head. Press the button and the beer explodes inside. As if by magic, the head appears on top. The aroma of a beer is released as the bubbles in the head pop. The Sonic Foamer allows you to start with a great head and recharge it at any time.
