3 step. Decorate play gear
① Fold the glued part of the ground picture, stand between the two cranks on the play gear, and attach it.
② Attach the hammer picture to the end of the I-shaped crank about 1cm.
③ In the same way, attach a mole photo to the end of the T-crank.
④ Hold the left side of the top as shown in the picture, and rotate the gear B to observe the movement of the mole and the hammer.
*Make your play gear fun by drawing on a blank sheet of paper in the kit.
The holes in Gear A can be used to change the height of the crank, or use the round cam included in the kit to vary the movement.
