Gyro game

There are bamboo gyroscopes, wood gyroscopes, plastic gyroscopes and so on.

First, the bamboo gyro method.

First, the thick cotton thread passes through the bamboo piece, and then it is wound around the bamboo handle. It should be noted that it should be wound from top to bottom. After winding, hold the thread end in one hand and pull it back, and hold the gyro and bamboo piece in the other hand and push it forward. When both hands exert force at the same time, the gyro will rush forward and make a buzzing sound.

Second, the wooden gyro method.

The first method is horizontal pumping, that is, bending down and throwing the gyro forward from the side. When the gyro leaves the hand, the end of the rope wrapped around the hand is quickly drawn back, and the gyro will rotate horizontally along the ground.

The second is vertical painting, which is a technique of holding the gyro above the head and playing while painting from top to bottom. This is a killer action. If you can't, you can't dispose of other people's dead gyroscopes, which is easy to suffer. Only by knowing this kind of play can you participate in the competition and win.

Third, the plastic gyro method.

Plastic rubber band gyro is also made of plastic. A top is like a flying saucer, but it has an up-and-down axis. The gyro is fixed on the pistol launcher by the tension of the blanket. When playing, turn the gyro with your left hand to tighten the rubber band. After loosening the batten, the gyro is fixed on the launcher, and then gently pull the trigger with your index finger, and the gyro will rotate.

Gyroscope principle:

When the gyro rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. In other words, the gyro "rotates" around its own axis and "precesses" around the vertical axis. In other words, the gyro does not stand vertically above the ground, but has a certain deviation from the ground normal and a certain inclination to the ground.

Therefore, the moment of gravity on the gyro is not zero, and the precession angular momentum of the gyro can balance the effect of heavy moment, so the gyro will not fall to the ground when it rotates. The speed at which the gyro "rotates" around its own axis determines the swing angle of the gyro. The slower the rotation, the greater the swing angle and the worse the stability; The faster the rotation, the smaller the swing angle, so the better the stability.

Moreover, the shape of the gyro also affects the precession of the gyro. This is similar to the reason why people ride bicycles. The difference is that one is linear motion and the other is conic motion.
