Build, turn, and watch science in motion! This kit lets kids
explore mechanical principles through a working grain
crusher.
By constructing the crusher, they see firsthand how a cam
and follower system works: as the cam rotates, its shape
pushes the follower up and down, converting rotary
motion from the handle into linear motion that crushes the
grains.
