A beer bong doesn't have to have an on/off switch on it. Just take a hose and a funnel, and viola! To stop the flow of beer coming down when you're pouring it in, just kink the hose in half and that will stop the flow.

That's how made our first beer bong. A hose, funnel and some tape, but then we got more creative and got a huge ass funnel, with this badass, heavy duty metal switch on it.

We called it The Rectifier, and after you did a few a few beer bong loads, you start feeling drunk and cock-eyed, and we'd yell, "you got rectified!" Good times.

How old are you Mac? I thought you were like 16 or 17 or something. Whoops!
