ThinkGeek presents a unique take on the traditional hourglass with a version that’s filled with magnetic filings instead of sand. As the tiny metal particles fall to the bottom, they stand up forming unusual organic shapes. Keep in mind that it’s not for actual timekeeping.

TaoFledermaus was playing around with some small magnets and decided to see what their movements would look like when captured at 4,000 fps with a prototype Chronos 1.4 camera. The resulting video reveals some of their strange and wonderful behaviors.

There’s nothing more to Stan Krzyzanowski’s video than a bunch of random metal objects being dropped one by one onto stacks of rare earth magnets, yet somehow it was compelling enough to hook us right from the start and make us watch all 99 seconds anyhow.

Apple is inexplicably phasing out its MagSafe cable, so we’re glad that companies like Griffin are picking up the slack. The BreakSafe is a breakaway power cable for USB Type-C devices such as the MacBook and the Nexus 6P.

Physics Girl and Arc Attack might sound like a superhero and her evil archnemesis, but they’re just everyday geeks who love science. Here, they show us how to rip an aluminum soda can to shreds using a powerful electromagnet, along with a couple of other fun experiments.

YouTuber Kaplamino added a very creative twist to marble mazes. He incorporated spherical magnets to pull off mechanics that would otherwise be impossible or complicated to set up, such as ricocheting balls and parts that trigger other parts without direct contact.

YouTuber DaveHax shows us how to make our own magnetic slime or putty. It’s actually very simple; all you need is some PVA glue, powdered borax and iron filings. This homemade version won’t last long though.

Destin of Smarter Every Day shows off a fascinating technology which allows magnetic fields to be printed into custom configurations. With this tech, engineers at Polymagnets can now “program” magnets that do exactly what they want them to do.

Magnetic Games shows off a cool, but dangerous setup that uses small nail-like projectiles that have been charged with the same magnetic polarity as their launcher, resulting in “darts” that launch solely under the power of magnetism. Don’t try this at home.

Learn about the extinction of left-handed magnets, the paradigm-shifting brownie-in-microwave experiment, a fun science activity for kids and mole people and more. Dear electrons, we know it’s hard for you to stay positive, but we appreciate you.

Beyond Slow Motion picked up a stack of colorful Magination magnets, then captured how dropping a single one into the mix causes them all to pull together toward each other. By adding some water and colored powder to the mix, the effect is even more impressive.

A sturdy belt that uses a durable aluminum buckle with a powerful neodymium magnetic catch. It closes easily, but holds strong. Like many things these days, it doubles as a bottle opener. We particularly love the carbon fiber edition.

Restrap’s Link belt has a magnetic ladderlock buckle that resists lateral movement but slides off easily,  so you can put it on, take it off or adjust its tightness using just one hand. The belt itself is made of durable elastic webbing.

Magzet brings Apple’s MagSafe tactic to audio jacks, detaching your headphone cable safely to protect your devices. It has two halves: one remains on your headphone cable’s jack while the other one goes into 3.5mm sockets.

A while back, Joey Shanks shared footage of some magnetic “thinking” putty as it engulfed objects. YouTuber Ian Parks has turned the idea into a bit of an obsession, releasing several videos of the unusual goo engulfing magnetic objects.

We already know that cats can be major assholes. As Kaipotainment’s video proves, we really don’t want these deceptively cute furrballs to gain the ability to willfully manipulate metal objects.

Watch what happens when two super-strong neodymium magnets are let loose to smash into one another, causing an impressive amount of destruction. And this is why you never put your hand between one and a piece of metal.

Kooba is a unique spin on darts, in which 2 to 4 players use a pair of sticks to fling their pieces onto its game board. The game includes a strategic element which challenges you to attack other players’ game pieces. Game rules here.

Magnetic boards made from planks and poles found along European and West Asian beaches, as indicated by the geographical coordinates branded on each board. Each board even comes with a photo taken when it was found.

A pair of small magnets that are meant to cover the front-facing webcam on computers. You can easily slide the cover away when you want to use the webcam, and they’re thin enough that you can still close your laptop with them on.

Cabin replaces the Lightning port on the iPhone 5/5S with a magnetic adapter similar to the MagSafe connector on MacBooks. The adapter works with Cabin’s battery case, dock and a magnetic adapter for Lightning cables.

Quit tossing your keys in the bowl and use this Magnetic Key Target instead. It has embedded magnets that will keep your keys up on it after a reasonable throw. Use the metal key ring to give yourself a better chance to hit the bullseye.

After making a replica of Wolverine’s claws, the lively Colin Furze tried his hands, er feet at emulating Magneto by creating a pair of magnetic shoes. Together with a steel bar, the shoes let him “walk” on the ceiling.
