This unique construction tool lets you check that things are level around corners or on staircases. It has four bubble levels and folds at four hinged points to wrap around angles. It has horizontal, vertical, and 45º vials, an aluminum alloy body, and built-in magnets for hanging it on metal surfaces.

The opposing forces of magnets can produce a tremendous amount of energy, and can even be used to levitate and move trains along a track. In this clip from Magnetic Games, he demonstrates these physics at work, though on a smaller scale using a bunch off-the-shelf neodymium magnets he got from Supermagnete.

You’ll never drop a driver bit again with the SwatClips magnetic bit box on your belt. This small case offers storage for drill and screwdriver bits and holds them in place securely with powerful rare earth magnets. Its lid opens 90º for easy access and it can keep up to 12 bits inside for longer-term storage.

Etsy seller BUproducts makes these unique decorative racks for organizing keys. The hexagonal honeycomb design is made from bamboo and has five magnets for holding its matching hexagonal metal key rings. The rack measures 11.2″ W x 4.3″ H x 0.4″ D.

Full Windsor presents a collection of magnetically-connecting plates and bowls that pair with their Magware utensils. These reusable steel dishes reduce waste and are great for picnicking and camping. They won’t blow away in the wind and stay neatly organized when packed. The side tabs make them easy to hold with hot foods inside.

You might think magnets aren’t particularly scary. But once you get a look at the attractive forces between two strong neodymium magnets, you’ll have a new respect for magnetic fields. The Slow Mo Guys show us how energetic they can be, capturing magnetic collisions at up to 187,500 FPS. You definitely wouldn’t want your hand in between those.

Magnets can be quite useful, but sometimes they’re just fun to play with. Magnetic Games is back with another series of setups that demonstrate how the vibrations caused by magnetic fields can make music, and how moving one magnet can set off a chain reaction between others.

A normal bike uses a set of gears to influence the amount of torque sent to its rear wheel. Tom Stanton wanted to see if it was possible to create a bike transmission that uses magnets to turn its wheel and create resistance. Put your thinking caps on for this brainy video that incorporates physics, math, and engineering.

Derek from Veritasium visited the National High Magnetic Field Laboratory to check out the strongest magnet on Earth. With a rating of 45 Tesla, it’s 15 times more powerful than an MRI machine. Along the way, you’ll learn about the strange ways that eddy currents affect objects in such an intense magnetic field.

This rechargeable light bar is perfect for working under your car hood, near breaker panels, or other metal surfaces. It has two powerful magnets and hidden swivel hooks for mounting versatility, and its 7800mAh battery pack can also recharge gadgets. It outputs up to 1200 lumens and offers four adjustable color temperatures.

A modern pinball machine needs computer circuits, electromechanical components, and a power supply to work. Magnet Tricks shows how it’s possible to build a playable mini pinball machine using only magnets and pyrolytic graphite. It takes advantage of the repulsive forces between the two to bounce a washer around its playfield.

Mehdi Sadaghdar was jealous of the views of an obviously fake video showing a magnetically-powered water cannon, so he decided to try and create something real that would approximate the same effect. Naturally, his experiments involved playing with dangerous electrical currents. Get ready to lower your expectations, folks.

What’s more fun than playing with powerful neodymium magnets? Adding high voltage electricity, that’s what! Magnetic Games shows us some of the fascinating kinds of plasma arcs that form as 20,000 volts are applied to different shapes, sizes, and arrangements of magnets.

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.
