The North Museum of Natural History & Science in Lancaster, PA previews its newest attraction: a quantum levitator. It’s a circular track of magnets above which a razor-thin disc magically levitates, seeming to defy the laws of physics.

Purchased for about $7,000 from Tel-Aviv University, the levitator is believed to be the only one of its kind in a United States museum.

The key to the levitator is the disc, which is made of superconducting material sandwiched between layers of gold and sapphire crystal. A piece of foam is placed on top and held in place with household plastic wrap. The disc is then dipped into a brew of liquid nitrogen (temperature: minus-300 degrees Fahrenheit).

While you’re here…
…We have a tiny favor to ask of you. Government think tanks have teamed up with Social Media Companies and Google to censor independent thought and government criticisms, and the result has been catastrophic for independent media. Despite this, The Mind Unleashed has survived without hiding our content behind a paywall, because we value open and accessible information more than we value profits. Hopefully we’re wrong, but without your help we're afraid The Mind Unleashed will algorithmically disappear from the Internet. Every contribution, big or small, will go directly into funding independent journalism. If you value what we’re doing here, you can help us keep going for as little as $1 and only a minute of your time. Thank you. Click here to support us
