Euler's Disk

Experience a wonder of physics as you spin Euler's Disk on the mirrored base.  Spin the disk on its side on the mirrored base, and watch as it gradually lowers itself towards a flat position as the intensity of its vibrations and noise increase. Fun fact: Euler's Disk would spin and roll forever if it were not for friction and vibration! This is a true marvel of physics that you have to see and hear for yourself. Includes:

• Patented 3" diameter chrome-plated steel disk
• 9" concave mirror base
• 9 piece of magnetized holographic foil
