Poetry, even the magnetic kind stuck to a fridge, isn’t to everyone’s tastes.

Watch A Ball Carve Beautiful Sand Art With The Secret Power Of Magnets

Bruce Shapiro’s Sisyphus is a magic machine that shows a steel ball rolling around in the sand to create wonderfully intricate sand drawings. The balls are all controlled with magnets but they seem to have a mind of their own. It’s like making a Zen Garden, only with the sorcery of magnets instead of old style rakes.


This Tiny Self-Folding Robot Will Destroy Itself When Its Job Is Done

Not content with creating a robot cheetah that can run and jump over obstacles at astonishing speeds, researchers at MIT have also developed this incredibly tiny origami robot that can not only fold itself, it can also walk, swim, and then destroy itself when it’s no longer needed.


Hardcore Recycling: Using Old MRI Magnets In A Physics Lab

Dayshot: When magnetic resonance imaging (MRI) scanners reach the end of their lifetime, hospitals have to deal with a large piece of electronic waste, stuffed with potentially dangerous parts. Unless a physics lab can make use of them.


Giant Magnet Goes On Cross-Country Trip To Find Self, Study The Universe

A special visitor recently arrived at Brookhaven National Laboratory after a weeks-long cross-country trek, requesting a homecooked meal and shower, probably.

Magnetic Buckyballs In A Blender Create One Terrifying Light Show

It didn’t take long for those “Will it Blend?” videos to get long in the tooth. You can only watch so many smartphones being torn to shreds before the novelty wears off. But to celebrate the birth of his 40th grandkid, Tom Dickson tosses a mountain of magnetic Buckyballs into the blades and the results are as spectacular as they are incredibly dangerous to try at home. Seriously, don’t try this at home.


Avoid Actual Work At Work With This Pen Made Of Magnets

The secret to a really effective desk toy is that it has to blend into your office. A pinball machine in the corner is just going to tell your manager you’re probably not getting a lot of work done. But a pen/tablet stylus made of magnets opens up a whole new world of slacking off, with your boss being none-the-wiser.
