Canadian chemist Muhammad Qureshi has taken the viral ALS ice bucket challenge to its logical conclusion by dumping a bucket of liquid nitrogen over his head. Undeniably, it was a very dangerous thing to do — but Qureshi did have some basic chemistry on his side.
We've all heard ice crack in water, because the water is warmer than the ice. What if ice cubes were dropped in something colder than they are? Take a look at a slow-motion video of an ice cube being dropped in liquid nitrogen.
We've shown you how to make smoke pellets, and they work very well, but they don't have the kind of instantaneous effect that we like to see if we're winged vigilantes of the night. If your enemies have you cornered, and you need to escape through a cloud of smoke, here something that might help you.
Stick a red or orange LED light into liquid nitrogen and the color will change. Why would cooling down an electrical device give it a higher-energy light? Find out!
A recent Jägermeister pool party in Mexico turned to panic after organizers poured four buckets of liquid nitrogen into the water, sending eight to hospital and leaving one partygoer in a coma. As you'll see in this video, things got ugly pretty quick.
We know that by heating things up can make them explode. How about by cooling them down? For those of you who doubt that you can make something explode by cooling it, just grab some white erasers and liquid nitrogen. Then stand back.
We can't get enough of this series of images by photographer John Shireman, who combines beatiful flowers, dead-simple composition and a rather creative use of liquid nitrogen to produce some of the most striking floral portraits we've ever seen.
Most of us think of liquid nitrogen as an extinguishing force, but it can, at times, rage against the dying of the light . . . bulb. Find out why a smashed light bulb stays lit if it's dipped in liquid nitrogen.
There are a lot of ways to deal with a person's body after he or she is done using it. Their last remains can be buried, burned, put in trees, or donated to science. But one Swedish company has a different approach to sending people off to their final rewards. Freeze drying. Just like the liquid T-1000 in Terminator 2…
Liquid nitrogen is famously one of the world's coldest substances, freezing and shattering anything it comes into contact with. But if you know what you're doing, you can safely stick your hand in it - as one brave blogger demonstrated.
