What is a beer bong?
A beer bong is a large funnel with a long, flexible tube attached to the end of it. A can of beer is poured into the funnel while the tube is bent so nothing can pass through it. When the entire can has been emptied into the funnel, the funnel is raised high above a person’s head. That person puts the tube in their mouth and undoes the bend. The pressure of the beer due to gravity forces the contents of the funnel straight into your stomach (minimizing the need to swallow) and allows you to drink the beer in a few seconds.
