Need tool materials: cardboard, pigment, fingertip gyro.

1, cut the cardboard into circles first.

2. Then draw an equally divided arc.

3. Then color.

4. paste the name of the prize on it.

5. Then make a pointer.

6. Color the pointer.

7. Stick the fingertip gyro on the big disc.

8. Stick the pointer on the fingertip gyro.

9. Stick a square cardboard with the same diameter as the CD on it.

Make a small turntable. Draw a big circle on a piece of cardboard, then draw a small circle and draw an arrow on one side of the small circle. Then draw a rectangle and two trapezoids with the same size, and cut out the big circle, the small circle and the trapezoid with scissors respectively. Prepare some paper icons to rotate.

Stick these icons on the edge of the big circle and fold two trapezoidal and small rectangular cardboard according to the two sides of the rectangle. Stick the arrow on the central axis and pass a nail through it. The front bracket, the large turntable and the rear bracket can rotate quickly.

Step 1: Cut the hard card into a circle. Step 2: pass a hard, sharp and slender pillar through the center of the circle (such as a toothpick). Step 3: If you can't rotate, replace the card with a light circular piece of paper, or use a rough toothpick-like thing as the rotation axis. Effect: a pillar in the middle and a round piece of paper outside. This is the simplest turntable.
