Students from the Ithaca College Low Temperature Physics Lab created a neat version of a quantum levitation track. It still uses supercooling and magnets to work its magic, but adds a fun (and literal) twist to by running its course around a triple-twist Möbius Strip.
The process of sandwiching oil and ferrofluid between sheets of glass is messy to say the least, but the result is amazing – the ability actually view the radiating fields created by magnets placed on the surface of the glass. Magnetic Games shows us how its done.
For Inventables’ fidget spinner challenge, Giaco Whatever decided to see if he could make one that could float in mid air. After a bunch of experimentation, he was able to get it to work by placing it between two opposing magnetic fields, and spinning it for stabilization.
Beyond its liquid properties, the other cool thing about mercury is that it’s magnetic. Roobert33 shows how electromagnets can be used to change the direction that mercury flows in. It would be cool to build an Escher-style fountain that flows uphill with this method.
This unique wall or table clock uses the power of magnetic levitation to float its hour hand (er, hour sphere) off its surface, creating a dramatic and minimal display as it casts a shadow on the wooden surface beneath. Want the exact time? An LED matrix display hides beneath the wood.
ThinkGeek presents a unique take on the traditional hourglass with a version that’s filled with magnetic filings instead of sand. As the tiny metal particles fall to the bottom, they stand up forming unusual organic shapes. Keep in mind that it’s not for actual timekeeping.
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.
Keep you keys from jingling and jangling every time you take a step with these tiny neodynium magnets designed to hold your keys together. They’re super slim, rust-proof, and attach easily to your keys. This set of 4 Magkeys magnets is 28% off in The Awesomer Shop.
