Last year's laser violin was the first re-imagined stringed instrument that didn't actually have any strings. And not to be outdone in the orchestra pit of the future, this year it's the cello's turn to get a fancy stringless upgrade.
Colin Furze, the guy who built fully automatic Wolverine claws, has now turned his attention to Magneto's power and made a pair of magnetic shoes. I was hoping that he found some way to make metal things levitate waving his hand, but this is still really cool.
I knew magnetic putty is a hungry gross thing that likes to eat stuff, but this doesn't look like magnetic putty at all. This looks like a hungry alien monster blindly looking to suck on some food (a giant magnet.) A 100-pound (45kg) magnetic putty monster.
