When I post Slow Mo Guys videos, it often comes with a warning not to try this at home. For their latest video, that deserves an extra-special mention: seriously, don’t try this. In this video, Dan and Gav explode lithium-ion batteries. In the process, they discover a safety feature - namely vents on one face of the battery. Because runaway thermal reactions (a.k.a. explosions) are a possibility with this type of battery system, consumer-grade batteries are designed to try and prevent extreme damage. One of these outwardly visible safety features are these four vents that release gas when when the battery is too hot. By venting the gas, manufacturers keep the battery from exploding and sending hot chemicals and shrapnel in all directions. Instead the venting gas turns the entire battery into a miniature rocket.

There will be drink. There will be science. There will be funny.
New Youtube series my friend and I are putting together. Come follow the facebook and youtube for more information!!!
If you dropped a water balloon on a bed of nails, you’d expect it to burst spectacularly. And you’d be right – some of the time. Under the right conditions, though, you’d see what a high-speed camera caught in the animation above: a pancake-shaped bounce with nary a leak. Physically, this is a scaled-up version of what happens to a water droplet when it hits a superhydrophobic surface.
Water repellent superhydrophobic surfaces are covered in microscale roughness, much like a bed of tiny nails. When the balloon (or droplet) hits, it deforms into the gaps between posts. In the case of the water balloon, its rubbery exterior pulls back against that deformation. (For the droplet, the same effect is provided by surface tension.) That tension pulls the deformed parts of the balloon back up, causing the whole balloon to rebound off the nails in a pancake-like shape. For more, check out this video on the student balloon project or the original water droplet research. (Image credits: T. Hecksher et al., Y.

It's been a while, right?? Well, it's been an interesting year. We're in the process of uploading all the episodes to vimeo. The first trailer is up. Go check it out again! Episodes are up weekly starting February 5. If you really want to help us out, please donate to http://ift.tt/2lqvuCQ #drunkscience #vimeo #webseries #science http://ift.tt/2FNIWrk
