5.Nanodots
Nanodots are some of the strongest magnets known to man and are giving fidget spinners a run for their money—they are made from a unique neodymium alloy and can lift 1,000 times their weight. These magnetic spheres are precision-milled and are designed to model atomic interactions on a human scale. Want to see how they work? Watch below!
6.Geared Whiplash
Puzzlemaster Oskar van Deventer has created is something he calls the "Geared Whiplash." This yo-yo gearing contraption is comprised of a snake of interlinked gear elements, which can be coiled up compactly or whipped out into a long chain. Once the whipping motion is complete, the contraption rolls up so the sequence can be repeated.
7.Moondrop
Most of us will never get to the moon, but if you've ever long to feel its low gravity weightlessness, you need not look further than the palm of your hand.
8.Lego Mac
Programmer Jannis Hermanns create this tiny Macintosh Classic using a Raspberry Pi Zero, an e-paper display, and of course, Lego, and, believe it or not, it works! Hermanns soldered a wifi module to a Raspberry Pi Zero and used a service called resin.io to update programs. He then used software called Docker to get limited functionality out of that e-ink display, such as showing a clock and other bits of information. We want one!
9.Tungsten Sphere
Though the Tungsten Sphere's is only 2" in diameter, it weighs well over 3 pounds. While it's not something you'll likely be juggling with or flipping between your fingers, it's a great conversation starter nonetheless.
