the_brit Ita called a beer bong lol, you place it over the top of a bottle of beer, a straw goes into the beer with air stuck in it. Pour it into your mouth and you can drink the whole beer in roughly 2-3 seconds. All good fun :)
sophieelizabeth91 Ahh! So they have actually made something that keeps the air flow going, kind of like holding the straw to one side like i do :)
annamarie1997 Like almost all of my family has one of these!
