Magnetic Games teamed up with Devcafe to create this fun hybrid live-action and CGI animation starring versions of Mario, Luigi, Sonic the Hedgehog, and Yoshi made out of tiny magnetic spheres. While participating in a round of Mario Kart they are pursued by a powerful magnetic block capable of ripping them apart.
Once you knock dominoes over, you generally have to set them back up by hand. But in the case of this LEGO Technic machine by Grant Davis, the dominoes stand themselves back upright. Running in an infinite loop of 10 dominoes at a time, it can knock down and stand up dominoes at a rate of 120,000 per day.
Full Windsor, maker of the Muncher multi-utensil, makes these great slimline aluminum eating tools. This literal flatware has embedded magnets and couplers for easy stacking in your drawer or backpack or for stacking them together at the table. Perfect for camping, or carry them daily to reduce environmental waste.
We’ve seen some unique clocks and timers, but this is the first time we’ve seen one that displays time using the kind of metal filings you’d find in a Wooly Willy toy. B.B. Korry created this electromechanical clock which uses a grid of electromagnets to attract and release iron filings to count down seconds. It’s really loud, though.
Holstery’s clip-on accessory attaches to your belt or bag, providing a strong magnetic holder for tools. Its made from durable Kydex and its internal magnet is powerful enough to hold hammers, pipe wrenches, pry bars, and other steel tools. It can also hold nuts and bolts so you don’t lose them while working on a project.
Magnets have some very interesting physical properties. Magnetic Games previously showed us how they can make each other vibrate. They’re back with three more minutes of neodymium magnets interacting with each other’s fields. That separator machine that works like a paper cutter is a cool idea.
Sometimes, the best kind of lock is the kind that doesn’t look like a lock at all. B-Star Crafts shows off a simple, but effective method that keeps doors or drawers locked using hidden neodymium magnets. It’s a trick that’s frequently found in puzzle boxes but can be easily applied to furniture and cabinets as well.
Magnet Tricks created a few cool kinetic sculptures using small neodymium magnet spheres and rods. They start spinning using air blown through a straw, and some of the designs incorporate colorful rods to create a rainbow effect as they get up to speed. They look easy enough to replicate using Neobuildr parts.
Electromagnets can be very powerful. They’ve even been used to get roller coasters and trains rolling and to launch fighter jets. Tom Stanton made a miniature system of homebrew linear synchronous motors which use electromagnetism to propel a small sled and launch various items including a hot dog and a paper airplane.
LEGO enthusiast Dr. Engine shows off a Technic machine that demonstrates how magnets can transmit energy through walls. Each of its spinning blades can turn without connecting to a central drivetrain thanks to magnetic fields. A gear-drive mechanism places each section in its precise sweet spot.
Looking for a different kind of fidget toy? Ukraine-based 3A Production makes these domino-sized plates that glide on each other using neodymium magnets. Each one is CNC machined from titanium, and they come in five anodized colors. Buy two or more sets to mix and match colors. Personalization is also available.
You can do all kinds of fun things with magnets, but we never thought of them as musical instruments. The guys from Magnet Tricks and Magnetic Games teamed up to create a series of sounds from magnetic vibrations, sampled them, then turned them into a synthwave track.
Magnetic fields can be pretty amazing. Given the right conditions, they can be turned into motors and even levitate. Magnetic Games shows off three different setups, each of which results in magnets floating and spinning with just a small boost of human or battery power.
Mechanical gears can change the speed or force by using different sizes and spacing of their teeth. But we had no idea that a similar result could be achieved by spinning discs embedded with different quantities and sizes of magnets. Magnetic Games shows off this surprising behavior in this neat physics demonstration.
There are countless videos on the Internet that claim to demonstrate machines that can generate their own energy and operate in perpetuity. Don’t believe the hype. In this video from The Action Lab, he shows off one such trick, which uses hidden electromagnets to make a sphere look like it’s spinning on its own.
Take a trip into space with this levitating planet lamp from Levitos. The illuminated planet floats and spins about 0.75″ above its base using electromagnetic induction technology and casts a colorful glow from inside of its orb. The planet and base measure about 5.25″ wide.
These pentagonal playthings have neodymium magnets embedded along their edges so you can snap them together into variety of shapes, including a dodecahedron. Each set comes with 12 pentagons, and the more kits you buy, the more complex the objects can get. Available in five colors.
Magnet fanatic Magnetic Games got their hands on 64 oversize 26mm (~1.02″) neodymium spheres. These giant-sized balls are much harder to work with (and more dangerous) than their smaller brethren, but they do look like fun. They’re not cheap, but you can buy some here.
Drop a marble into the top of this tabletop sculpture, and it rolls down a ramp and back into itself endlessly. While it might appear to defy the laws of physics, the trick is that its base contains a hidden battery and electromagnet that accelerates the steel sphere as it comes down the ramp.
Cooling yttrium barium copper oxide (YBCO) to -180°C creates a superconductor that levitates when placed in a magnetic field. Magnetic Games demonstrates the strange physics at play using powerful neodymium magnets for the supercooled puck to interact with. Turn captions on for more details.
Discovery UK digs into the How It’s Made archives for this look at the process that goes into creating magnets. After melting a cocktail of various metals in an electrical induction furnace, the fiery metal is poured into sand molds, then cooled, separated, and charged with multiple electromagnetic fields.
The way that Venom comes to life from a pile of black ooze is awesomely creepy. JLaservideo wanted to replicate the effect in real life and figured out the best way to do it was to create a suit from 100,000 neodymium magnets and latex, then let ferrofluid do the rest of the work.
