How to make a top from paper
The spinning top is a classic toy that both adults and children love to play with. If you don't have a ready-made spinning top on hand, try making one out of paper. This article will introduce in detail how to make a top from paper, and attach the hot topics and hot content in the past 10 days for your reference.
1. Steps to make a top from paper
1.Prepare materials: You need a square piece of paper (it is recommended to use slightly harder cardboard), a toothpick or thin wooden stick, glue or double-sided tape.
2.fold paper: Fold the square paper in half diagonally to form a triangle, then unfold it. Then fold the other diagonal line in half and unfold it to form two intersecting creases.
3.Make the top body: Fold the four corners toward the center point to form a small square. Then flip the paper over and fold the four corners toward the center again. Repeat this step 2-3 times until the paper becomes thick.
4.Fixed central axis: Pass a toothpick or thin wooden stick through the center point and secure with glue. Make sure the toothpick is vertical and secure.
5.test gyroscope: Gently rotate the toothpick to observe the balance of the top. If an imbalance is found, the symmetry of the fold can be adjusted.

3. How to play paper tops and techniques
1.spin tricks: Hold the toothpick with your fingers and rub it quickly to make the top spin on the smooth surface. Try to keep the force even when rotating to avoid using too much force and causing the top to tip over.
2.Balance adjustment: If the top spins wobbly, the fold may be asymmetrical or the toothpick may not be vertical. The position of the folded or fixed toothpick can be re-adjusted.
3.creative decoration: To make the top more beautiful, you can draw colorful patterns on the paper or put stickers on it. Not only does this make the top look cooler, but it also adds to the visual effect when spinning.
4. The scientific principles of paper tops
As the top spins, the principle of conservation of angular momentum keeps it stable. Although the paper top is light, it can rotate very stably as long as it is folded symmetrically and the central axis is firmly fixed. By making paper tops, children can gain an initial understanding of the concepts of rotation and balance in physics.
5. Summary
Making a spinning top out of paper is not only simple and fun, but also exercises your hands-on skills and creativity. Through the steps and techniques in this article, I believe you will be able to make a paper top with stable rotation. At the same time, paying attention to recent hot topics can also keep you abreast of the times and enrich your knowledge base. Come and try it!
