The Slow-Mo Guys ignore all the warning labels on a bunch of small lithium batteries, exposing them to fire, and turning them into tiny rocket ships and bombs in front of their Phantom high-speed camera. We can only imagine how nasty large batteries would be if they blew up.
THE BEST Experiments
We’ve seen the fire tornado trick before, but if you know Colin Furze, you know he’s always got to go to 11. Now, the British madman has gone and built himself a 20-foot-tall spinning fire rig that’s every bit as terrifying as an actual tornado. Oh, and it shoots fireworks.
The Science Channel’s series Street Science presents a neat experiment, mixing bulk quantities of the nasty goo inside of glowsticks to produce a variety of vibrant colors. The result is a new abstract painting medium. Needless to say, don’t play with these chemicals at home.
We’ve seen the strange properties of these hardened glass drops before. Now see how one handles the deadly hydraulic press. It’s so strong that it damages the press tools before violently exploding. Hopefully these guys can buy a better high-speed camera soon.
The Backyard Scientist adds a propane torch to his sweet rocket sled knife so he can heat the knife’s blade to over 1000ºF before launching it towards its inanimate victims at the end of the track. It didn’t stay glowing hot, but slow-mo rocket sled destruction is still fun to watch.
The power-mad minds at PhotonicInduction decided to see what would happen if they attached a length of steel chain to some high-current transformers. At first, all they were able to muster was a few sparks, but with a higher output power source, it glowed bright orange.
A cool science demonstration which shows how the electrons swirling around the outside of a Tesla coil can turn it into an impromptu motor – in this case, causing a wire balanced on top of it to spin and shoot sparks as it goes. Originally seen in a video from ElectroBOOM.
Physics Girl and Arc Attack might sound like a superhero and her evil archnemesis, but they’re just everyday geeks who love science. Here, they show us how to rip an aluminum soda can to shreds using a powerful electromagnet, along with a couple of other fun experiments.
A brief demonstration of what happens when you submerge a styrofoam cup in acetone. The solvent properties of the acetone dissolves the polystyrene and the cup vanishes into a pile of goo. One commenter pointed out this chilling reference from Who Framed Roger Rabbit?
(PG-13: Language) Folding paper in half exponentially increases its strength. At seven folds, it’s as thick as 128 sheets of paper. You can go beyond seven if you use a really long sheet, but Hydraulic Press Channel tried it with a small piece – with unexpected results.
We’re not sure of the health implications of eating steak cooked in molten copper, but it’s still cool to watch as this raw T-bone is cooked to within an inch of its life as YouTuber Tito4Re douses it with hot liquid metal. Cooking rice the same way doesn’t work quite as well.
The Backyard Scientist has made a habit of pouring molten aluminum into things to see how it will interact with them. This time, he pours the hot metal into an aquarium filled with thousands of water-absorbent polymer beads. The resulting sculptures are totally awesome.
