TRINKETS

Nitinol is a special alloy of nickel and titanium that has an interesting property called shape memory.  This means the metal can undergo deformation at one temperature, then recover its original shape at another. This sample’s transition temperature is around...

These little pieces of metal represent value to facilitate exchange for other items. Coin minting is one of the oldest ongoing activities of civilization, with standardized metal ingots being used as long ago as the 11th century BCE. Modern coins...

Ferrofluid is an iron-based liquid that reacts in the presence of a magnetic field.   Comprised of nano-scale magnetic particles suspended in a transparent liquid, ferrofluid aligns itself to a magnetic field, making it easy to visualize the field. With this amazing magnetic...

Anyone who’s worked with tiny screws knows how convenient a screwdriver with a magnetized tip can be. With this magnetizer, you can magnetize (or demagnetize) your own screwdrivers. This tool takes advantage of the magnetic moment. Think of each atom...

The Audubon bird call is a simple machine used to imitate and attract many bird species. The bird call’s sound is produced by rotating the birchwood cylinder against the cast zinc plug. By varying the pressure between the two surfaces...

WE LAUNCHED THIS PRODUCT ON KICKSTARTER AND IT WAS FUNDED OVER 200% If you compress any amount of mass, it becomes denser. If you compress it enough, it will become so dense that light can no longer escape it—this size...

We don't usually carry religious paraphernalia, but we had to make an exception for these liquid-filled glass dreidels.  When spun, the colored water in the internal cavity exhibits interesting physics to keep the top spinning. Includes stand.Dimensions: 3" tall x...

A rattleback is a type of spinning top that prefers to spin in one direction due to its unique semi-ellipsoidal shape. When spun in the wrong direction, it will automatically shift the momentum until it spins the opposite direction. This...

These solids of constant width behave like spheres. This is because, regardless of the peculiar shape, the diameter is still equal at every point. You can demonstrate this property by setting a flat object, like a book, on them and it will...
