Self-Pouring Liquid Behaves Like It's From Another Universe

Video: Growing up on Earth you learn from a very young age that liquids will remain in a cup as long as it stays upright. But Steve Mould demonstrates a liquid that laughs at gravity and other forces that govern our universe: Polyethylene oxide. It’s a polymer made from long chains of molecules that allow it to pour itself out of a container — even if it’s not tipped over.

Google's New Science Journal App Turns Your Android Phone Into A Lab Full Of Sensors

If you’re working on a rocket destined for Mars, Google’s new Science Journal app might be a bit limited. But if you’re an aspiring scientist, the free app will turn an Android smartphone or tablet into laboratory full of experiments by grabbing data from the device’s various sound, light and motion sensors.

A Few Scraps Of Paper Can Turn Dirt Into A Super Strong Building Material

As far as building materials go, they don’t come much cheaper than dirt, which is literally everywhere and mostly free. But, as anyone who has ever made a sand castle knows, soil isn’t terribly strong and has a habit of forming a shallow pile rather than more structurally-beneficial shapes. We’re going to let you in on a little secret — making dirt super strong is incredibly easy.

Lighting 100,000 Sparklers At Once Is The Quickest Way To Make A Working Volcano

Video: Igniting 10,000 sparklers at once was a cute way to ring in the new year, but assembling 100,000 sparklers into a tower and adding fire is probably as close as one could get to building an artificial working volcano.

5 Totally Bizarre Ways To Put Out A Candle

Video: How do you put a candle? It’s simple, just blow it out. Easy enough, right? But so not interesting. The always inquisitive Physics Girl shows us five weird and wacky ways to kill the flame from a candle and each are more interesting than the next. You could use a copper coil or a rounded obstacle or an open glass cap or pouring CO2 onto it or even just freeze the flame with liquid nitrogen.

Chopping Open A Giant Rubber Band Ball Basically Reveals A Hidden Monster Inside

Video: A giant rubber band ball? So much fun. Just slice the thing open and you’ll see it quickly grow and explode up and basically unleash the monster that wants to escape from its rubber ball prison.
