So your buddy mistakenly buys Busch Light and brings it over to your house. She shows up, you frown at her, but then you remember. You have Fizzics! This gadget will give that light yellow beer a proper craft beer foamy head. Will that foamy head play a part in making your beer better? According to Verge, yes!

I know what you’re thinking. This sounds like the kind of corny device you would have found in a Skymall catalog (RIP). That’s true. But it also works really well!

They currently have a $50,000 IndieGoGo Campaign going on to raise the money to put it into production.

Here’s how it works:

“When you’re doing a hand pour, to get a nice head on it, usually you pour straight down,” says Fizzics co-founder and CEO Philip Petracca, a beer nerd of the highest order. “That gives you some fairly large bubbles but actually uses up most of the carbonation in the body. Nucleation is the technical term. Not to mention those bubbles dissipate quickly.” The Fizzics produces small, tightly packed bubbles that last quite a while without killing off your carbonation. And because it does it with sound waves, instead of nitrogen or some other additive, it doesn’t change the flavor of the beer.

Cost is $119 a unit. Good or bad for craft beer? Would you buy this?
