Young & Old, Look and Listen to Euler’s Disc
Euler’s Disc is an excellent science toy. The disc is quite heavy and has a flat edged side and a beveled edged side on which you spin it on top of a supplied round mirrored base. Potential energy is converted to kinetic energy as the disc spins faster and at the same time gets closer and closer to the mirror to eventually stop flat with a high pitched sound. Both seeing and hearing the disc makes for an entertaining show. Various patterned magnetic designs are also supplied and can be applied and removed on the disc surface. This allows for a visual diversity of light patterns to reflect off of the disc while spinning. I highly recommend this interesting scientific and entertaining toy for anyone, young or old.

Euler’s Disk is a lot of fun! Watch as potential energy converts to kinetic energy as you let the disk spin on the mirrored surface that is included. It is a visual and auditory delight as the spinning gets faster as the disk gets lower and closer to its base. Science can be fun, fun, fun, with Euler’s Disk!
