In the newest video from slo-mo YouTube celebs Gav and Dan, we get to experiences a common childhood dream turned smartphone nightmare: watching batteries explode.
While these aren't the more powerful and sophisticated lithium batteries that power your gadgets, it's still gives you a good understanding why Energizer and Duracell put copious warnings on its packaging. Starting with watch batteries, the display is dramatic. The explosions cause loud popping sounds and flying detritus, like the part of the watch battery that nearly hits Dan in the face.
When they move over to your standard Energizer AA lithium batteries things get even more intense, with giant plumes of smoke and a big fiery explosion, which is particularly gorgeous in slow motion. Enjoy, and don't try this at home.
