Did you know putty can do more than be smooshed around and stretched into weird shapes? It can if it’s Scientific Magnetic Space Putty.
Like regular play putty, this stuff is still viscoelastic for all the funky stretching and stress-relieving. But this putty is also embedded with magnetic properties, so you can use it to interact with magnets. It even bounces, so the possibilities for play and fun are virtually endless.
Wow your kids (or even your coworkers — magnetic putty doesn’t discriminate by age) with Scientific Magnetic Space Putty. Try it out for only $9.99(USD) at the Technabob Shop.
Satellites often rely on reaction wheels, or constantly spinning flywheels, to tweak their attitudes without using precious fuel. However, they tend to be very delicate -- since they use ball bearings, they spin relatively slowly (under 6,000RPM), ta...
Until now, humanity has only known two forms of magnetism: ferromagnetism (the kind you see on your fridge) and antiferromagnetism (a sort of negative magnetism found in hard drives). However, MIT researchers just confirmed the existence of a third...
