Prepare the hands-on activity
Use the source reference’s 3:1 diameter ratio to predict how many times the smaller disc will turn.
REFERENCE VIEWS · IMAGE SEQUENCE 15 sec
Coin Rotation Paradox Exhibit — design views
Design-image sequence
Inspect the reference images.
Compare Coin Rotation Paradox Exhibit in five labelled still views. Turn a handwheel and compare a coin model's spin with its travel around another circular model.

Look at the action.
Understand the reference.
Inspect the large and small discs, their relative arrangement and the handwheel in the catalogue views. This still-image sequence does not measure the rotation count in motion.
Plan the comparison
Compare one external orbit using a fixed tabletop direction and the rotating line joining the disc centres.
Question to explore
Are you counting spin against the tabletop or against a rotating reference? Distinguish a disc's orbit from its spin.
This film sequences existing reference images. It is not continuous operating footage or a moving 3D simulation; final function and configuration follow the agreed project.
