Nanodots are the strongest magnets on Earth and so much fun

These precision-milled spheres let you procrastinate with atomic modeling.

They may look like simple ball bearings, but Nanodots are some of the strongest magnets known to man. Made from a special neodymium alloy, they can lift 1,000 times their own weight. This is probably the coolest desk toy ever, and you can get Nanodots 216 Sets now for $34.99 at the Popular Science Shop.

These precision-milled spheres are the perfect way to procrastinate during boring days at work. Made from sintered neodymium-iron-boron, each Nanodot measures just 5mm in diameter. However, they are ridiculously strong and great for building models.

Originally, they were designed for creating atomic models at human scale. But many people have adopted Nanodots as K’nex for adults. The spheres lock together in whatever shape you want, and they are engineered to take everyday use. The spheres also have an antibacterial coating. Each magnet should last for 20,000 years, so you should get plenty of use out of each pack. It’s like having a force of nature in your hands.

Normally priced at $39.99, the Nanodots 216 Sets are now $34.99—choose your preferred color on the deal page.
