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.
