Sonic Hour gives beer great head

Beer foam is the bane of any frat party, but it’s a sign of fresh beer. They love it so much in Japan that Takara Tomy Arts created a device called the “Sonic Hour” (ソニックアワー) to create even more foam. This isn’t their first device used to get head, but it is the newest. Just like the Jokki Hour mug, the actors’ reactions are the best part. It’s as if they are seeing sorcery in action.

It isn’t sorcery though, it’s sonic waves sent through the beer to agitate it. Guinness has a nearly identical product called the Surger which is meant to give a can of Guinness the same head you would get at a pub.
