Sounds perfect. 

Want a better head on your beer? A new gadget called Fizzics promises the perfect head on beer every single time by using sound waves. 

Yes, American Bars agrees that getting the perfect head on a glass of beer can be a fine art. However, a new gadget promises to create the optimum amount of foam every time using sound waves. 

Called Fizzics, the machine claims to offer to ‘elevate store bought beer into a draft quality beer, the way the brewers intended it to taste’ and can be used with any beer of a user’s choice. Curious? So are we! 

It pumps high-frequency sound waves through beer to make thick foam to sit on top, enhancing the flavor of the drink.

Beer is inserted into the prototype gadget and connected with a plastic tube so that once the lid is closed, the liquid is sealed in an airtight container. 

Users then push a lever forward on top of the device to suck beer through a nozzle, before pushing it back again to pump high-frequency sound waves though the liquid, to produce thick foam.

In particular, the gadget is concerned with three different phases of 'fizz'.

Nucleation, when the bubbles start to form, beading, which is when the bubbles rise to form a head, and disproportionation, which is when the bubbles mature. 

Fizzics reduces excessive bubble formation by pressurising the canister and pouring the beer at a controlled rate.  

The machine pumps high-frequency sound waves through beer to make thick foam to sit on top (pictured right) compared to a normal pouring method (left). The thicker foam with smaller bubbles is said to last longer and make beer taste smoother. 

Hey, what else are those ex-NASA scientists supposed to do these days?

This is done by using high frequency sound waves and oscillation technology without the need for CO2.

And it means that the foam produced is thicker with smaller bubbles and lasts longer than for beer simply poured from a bottle into a glass. Ah, technology makes life better every day!
