First off, don't do this. Seriously. Don't. It's an old trick, and probably a great way to stab yourself in the eye with a flying bottle cap. But it sure looks pretty in slow motion, as the goofballs at Slow Mo Lab are here to show us.
Sure, you could just use a real bottle opener, or buy your beverages in twist-off bottles. But where's the limb-risking fun in that? This way, you can have your drink ready without interrupting your gardening.
No but seriously, do not do this. Do not. Don't. [Slow Mo Lab]
