If you like your beer extra foamy, this beer head enhancer is a tool you need to add to your bar cart as soon as possible. Available from Japan Trend Shop, the Beer Can Foamer addresses the Japanese preference for beer with lots of foam at the top. The drink-frothing device works even on cans of beer to create the thick beer collar. To use, you simply snap the beer head gadget onto the can and press the top. The battery-powered invention is easy to use and clean and even comes in three different colors (yellow, red and green).
Theoretically, the plastic foamer could be used on any can, if you are into frothy beverages in general. This could work quite well on a can of coconut milk for a cool summer beverage.
