Want a little head with your beer? The “Beer Hour” beer dispenser from Takara Tomy helps wannabe bartenders to pour a perfect, foamy-headed glass of beer every time from any beer can.

The device, which comes in your choice of yellow or black & yellow plastic, clamps onto most any make of beer can in from 350ml to 500ml in size. Press down on the “bubble lever” and watch your mug fill up with beer and foam in the optimal 7:3 ratio.
