That Little Disc Under A Bottle Cap Is Necessary
If you’re like us, you used to pry those little plastic discs out of water bottles, soda bottles, beer bottles, and any other bottle that contained one. Really, what possible purpose could those little plastic discs actually serve aside from being turned into really weird ’90s bracelets?
Truth be told, those little discs keep everything in the bottles! The water, the carbonation, the whole enchilada. Without that ring, you’d have a flat soda in no time and it would be leaking through the top of the bottle was ever knocked over. Keep that in mind next time you’re feeling bracelet nostalgia.
