If you are unfamiliar with beer tubes, you should know that it is a simple device that uses gravity to dispense your brew quickly. Fast beer pouring means fast drinking and fast drinking means you will probably have a few scenes missing from the Saturday night feature film rolling in your brain. There are plenty of unique beer tubes out there and a few must-have accessories to go along with them—like this siren lid.
The sirens purpose is twofold—It lets your host know that you need that next tube of beer pronto and it warns the other guys in the room that you are going to be the jackass that they will have to punch before the night is out.
