2. Stick the bottle cap of mineral water or soda bottle in the middle of the other side of the CD, and just sew the round hole on the CD.
3. Stick a layer of wrapping paper on the surface of the CD with double-sided tape, and a DIY gyro that turns waste into treasure will be ready.
4. When the top is rotated by twisting the bottle cap, a relatively static illusion pattern will appear on the top, because the rotation is told to give the eyes an illusion.
Gyro is a very playable toy. Making a red-handed gyro for your baby can train your child's concentration, thinking and creativity. Especially when DIY gyro is completed by parents and children together, it is also a good early education to tell the baby the principle and history of the gyro in this manual production process.
