If you're heading to the beach this weekend, want to make sure your beer stays cold, don't want to spend $2 on a beer koozie, AND don't mind looking like an EXTREME REDNECK . . . we've got your solution.
A woman in Louisiana realized you can use a TOILET PLUNGER as a beer koozie. Your beer should fit nicely in the mouth of your plunger, which keeps it cold, and you can plant the handle in the sand to keep it standing up.
We recommend cleaning your plunger first before you do this. (Al.com)
