This is brilliant. Anytime you have a friend that comes over to watch the game and brings over ---smurfy---, cheap beer. You just spend the game launching it back into his face. Then, since the beer was flung across the room, the beer will foam all over when opened. So as an additional benefit, you get to yell at your friend for spilling his cheap beer all over your furniture, and make him pay for a cleaning service to clean out your fine leather couch.
As an added bonus, since it is available via phone app, you can see anyone using your rec room when you are away. So if the wife or kids think that because you are away, they can touch your stereo system, you just pop on your phone and launch a cheap beer can into their eye. That will teach them.
Invention of the year right here, folks!
