Batteries are a blessing and a curse. When you're vegging on the couch with a remote or outdoors with your camera, they're the best invention ever. They're not so great when they die at exactly the wrong moment and you don't have replacements.
Let's say you have replacement batteries nearby, but they've been sitting in a drawer for who knows how long, and they've lost a lot of juice. If it's anything like in my house, there's an entire box of batteries sitting in a junk drawer, with both dead and alive batteries all mixed into one grab bag.
You need to have a way to know whether your batteries are dead or if they are still kicking. Thanks to science, there's a free and easy way to tell.
It's as simple as throwing your batteries on the ground. Yes, you read me right. Next time you need to see if your batteries are dead or alive, throw it on the ground. If it's dead, it will bounce. If it has juice, it won't bounce.
All this is according to a new study from researchers at Princeton University and was published in the Journal of Materials Chemistry. See a video of the experiment below:
