Endless Levitron
Comments (0) Dunno if you know it, but a Levitron is sort of a toy consisting of a magnetised board that creates a levitating effect with a magnetised spin.
It’s an old idea and toy that explores magnetic properties to create the effect. You probably already saw something like it in display at stores, with levitating globes and whatnot.
Leave it to researches at Johannes Gutenberg University in Germany to give the idea an upgrade, using a Helmholtz system to make it levitate heavier objects or make the spin stay floating for 5 hours! So yeah, it’s not REALLY endless… but still, that’s far more than the couple of minutes normal toys are capable of.
Interesting huh? If you’re wondering why no one made a floating car or whatever out of it, you need to read a bit more about the whole idea to realize it won’t work that way, unfortunately.
