Need a new way to impress your friends? Well, when you're out partying, show them how to break a beer bottle with you bare hands. This bar trick is sure to amaze anyone, and it relies simply on air pressure. Just keep in mind that this could be dangerous... glass will fly.
Take the empty beer bottle, fill the bottle up with cold water, until there is an inch left at the top of the neck. Hold the bottle by the neck and smack the rim of the bottle as hard as you can with your palm, and that's it!
