In the past, glass manufacturers added uranium to glass for color. Uranium has since become more strictly regulated, but the old uranium glass objects are still floating around. Because of the uranium content, these marbles glow bright green under ultraviolet light. Size is around ⅞ – 1” diameter. Some dents and manufacturing imperfections can be expected. Slightly radioactive, but they're harmless. Makes... More info

This simple piece of glass is a powerful tool for examining the electromagnetic spectrum. As light enters a prism, it changes speed going from one medium into another (air into glass). Since every color is made of photons vibrating at unique frequencies, they bounce off the glass walls at unique angles. This causes white light to fan out into the... More info
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 is caused by an asymmetrical mass distribution and the instability between the rotational axes. As the mass shifts, the rolling... More info
Originally made famous by Admiral FitzRoy, the captain of the HMS Beagle which Charles Darwin made his renown voyage upon, this sealed glass contains a solution that can form various crystalline structures, even filling the glass at times. This behavior was long thought to be indicative of the current weather conditions; however, these devices are now known to have little... More info
This spinning top has a surprising behavior. When spun, it will invert itself to spin upside down until it loses momentum. This interesting gyroscopic effect is generally credited to surface friction. This small friction causes a torque which gradually rotates the sphere on a second axis and forces it up onto the stem. Note the direction of rotation before and after... More info
