ARCHIMEDES' GEAR science-biology Race them all and recordInspired by Archimedes' use of mathematical precision, this set of interlocking gears relies on imagination and resourcefulness to solve. At its core, this extraordinary puzzle features an array of metal pins strategically positioned to hold the gears in place. Discover the detachable element responsible for disengaging the magnetic pins, allowing the gears to shift and separate. Delicately separate the top and bottom layers to expose the hidden force
