Beer Bong
If you've never been able to show off your drinking skills to your mates, then grab a hold of one of these party shooter Beer Bongs and get ready to impress as you down a drink in seconds!
How it works:
Just place the thin tube inside a glass bottle and secure the large drinking tube onto the top. Place your finger on the vent-hose and place your mouth around the Beer Bong. Tilt your head back, get ready, take your finger off the vent-hose and it all comes down in seconds!
Tests show that the liquid from a 330ml bottle will come out by an increase of 266%! Just make sure you've got an empty stomach!
