Sometimes, you just want to see someone smash a Pepsi with a hammer. 

The taste of a new generation, Pepsi, has long played second fiddle to Coke, which is far superior. But now soda #2 has something over big red: This video of someone covering a can of Pepsi in liquid nitrogen and smashing it with a hammer. 

Coming to you from science YouTuber MrGear, this video delivers as promised. MrGear pours liquid nitrogen on stuff, like berries and lettuce, and sees if it'll shatter in his hands. It's extremely cathartic. 

Astronaut Kjell Lindgren is getting his space suit and tool belt ready to walk in space tomorrow.

America is the land of inaccurate, outdated, and totally worthless measuring systems. While the U.S.A is one of three countries to scoff at the metric systes (along with our dudes Liberia and Myanmar), we also use a little thing called Fahrenheit when measuring temperature.

The U.S.A and its associated territories is one of five countries to use Fahrenheit (along with our dudes the Bahamas, Belizem, the Caymen Islands, and Palau), but why do we use this outdated system and where did it come from?

This handy video from the YouTube channel Veritasium answers at least one of those questions. Turns out it has origins a lot like Batman. When a young scientist’s parents die suddenly, he goes on the run and becomes obsessed with cool science gadgets. From there, he starts fighting crime, and by crime, I mean inconvenient and inaccurate temperature scales. Anyway, it makes sense in the video.

It’s entertaining, interesting, and as always will make you smarter than anyone in the room.

Science, y'all!:

It's harder to create movement in water than in air, because water molecules are closer together than air molecules. To show the difference in resistance, physicist Andreas Wahl puts himself in front of a weapon submerged in water and fires it - on himself.

Surprisingly the only shocking thing is that two adults agreed to shock themselves with them.
