Wind-up Spin Art & Light Machine!
Separate your cardboard pieces and unpack your wind-up mechanism.
Insert wheel until axle touches cardboard edge. Slide & carefully press fit mechanism into slot.
Lightly press fit and adjust the other piece on the wheel. Give the mechanism a test twist.
Practice holding, winding up & releasing the mechanism. Over-winding / reverse winding does damage!
Add a stack of sticky notes to the platform. Wind up and touch your marker - watch what happens!
