The Japanese beer brand produced a small household version of the machine
featured at the baseball stadium. It's called a beer slushie machine, but it
doesn't exactly make slushies.

The machine blows cold air into the beer until it gets down to 23 degrees
Fahrenheit. Then it dispenses a frozen foam to top your beer.

The machine was originally used by Kirin as a promotional item, but due to
its popularity, the company is producing them for at-home use. They are being
sold on a site called Japantrendshop.com for $100.
