Tips for playing tops.

The technique of throwing a spinning top (with a top diameter of 2.5 inches to 3.3 inches is the most proficient).

Rope wrapping: The nail is facing upwards, and the right-handed person is wound in a clockwise direction (the left-handed person is in the opposite direction), and a short section is reserved to tie a single knot for holding the rope (or wrapping around the finger).

Holding: Nailed up or left top down or right, with the thumb, index finger, middle finger upside down to hold the top.

Throwing method: The distance is chosen by the length of the rope and the length of the arm, the arm swings towards the target, the middle finger of the spinning top leaves the hand pointing in the direction of the target, and the strength depends on the accumulation of experience through continuous practice.

Tips for hitting big tops:

Rope wrapping: Place the nail facing up, wrap two to three times according to the length of the top tip, and then wrap the rope from the top to the top of the top to the top of the top from the tip of the top to the top of the top, and tighten it in order, about one-third of the best.

Upper top: Hold the top circumference of the top with a rope in one hand, hold the tip of the top in the other hand, hold the top and lean on the legs, and prepare the tip of the top forward and downward. When throwing the top, the hand holding the tip of the top leaves immediately, and the other hand holding the rope holding the top circumference of the top of the top rotates to generate rotational power, and then the two hands pull the rope interchangeably, so that the top will not fall to the ground.

Run quickly in the opposite direction, don't look back, and wait for the rope to finish.

1.The bottom of the top should be smooth and hard, and marbles are better.

2.The greater the mass, the greater the inertia, which is stable.

3.If you want to rotate fast, the moment of inertia should not be too large, so do not make it too coarse, or the mass should be concentrated near the rotating shaft as much as possible.

Fast and stable can not be both, coordinated.

Reduced friction, high initial velocity, the shape of the gyroscope is relatively balanced.

1. Paper spinning top, due to the small size of the paper spinning top, as long as you use your thumb and index finger to hold the upper end of the shaft handle of the paper spinning top tightly, and twist it quickly and put it on the table, the paper spinning top will rotate independently with one foot.

2. Copper coin spinning top, the gameplay of copper coin spinning top is also the same as paper spinning top, twisted by hand, you can rotate.

3. Spool gyroscope, the way to play spool gyroscope is also to use hand twisting to rotate.

4. Bamboo spinning top, first pass the coarse cotton thread through the bamboo piece, and then wrap it on the bamboo handle, it should be noted that it should be wound from top to bottom. When you wrap it up, hold the end of the line in one hand and pull it back, and when both hands exert force at the same time, the top will rush forward and make a buzzing sound.

The square is placed in the middle position, the triangle is placed at the bottom, and the circle is placed at the top, and the three can be strung together with matches.

The spinning top is the earliest entertainment tool of the Han people, also known as Dhara, and is called in Hokkien language"Dry music", which is called in the north"Bing"or"Fight the old cow of the round god"。The shape is rounded in the upper part and pointed at the bottom. In the past, it was mostly made of wood, but in modern times, it is mostly made of plastic or iron.

When playing, you can wrap the rope and draw the rope vigorously to rotate upright. Or use the spring's elastic force to rotate. The traditional ancient liquid spinning top is roughly an inverted conical shape made of wood or iron, and the gameplay is to split it with a whip.

In modern times, a wide variety of materials (e.g., steel, plastic, etc.) and shapes (e.g., lumpy) have emerged.

Of course, there are some more"Hand twist the top"Very popular. Spinning top is a very familiar toy for teenagers. Popular all over the world.

China is the home of the spinning top. Stone spinning tops have been excavated from Neolithic sites in Xiaxiangxiao County, Shanxi, China. It can be seen that there are the least number of spinning tops in our country.

Four or five thousand years of history.

When the top rotates, it not only rotates around its own axis, but also makes a conical motion around a vertical axis. That is, one side of the top is made around its own axis"Rotation", one side is made around the vertical axis"Precession"。That is, the top does not stand perpendicular to the ground, but has a certain deviation from the ground normal, and has some inclination to the ground.

So the moment of gravity on the gyroscope is not zero, and the precession angular momentum of the gyroscope can balance the action of the gravitational moment, so the gyroscope does not fall to the ground when it rotates. The spinning top is made around its own axis"Rotation"determines the size of the spinning top swing angle. The slower the rotation, the greater the swing angle, and the worse the stability; The faster it rotates, the smaller the swing angle and therefore the better the stability.

And the shape of the top also has an effect on the precession of the top. This is similar to how people ride bicycles, except that one moves in a straight line and the other moves in a conical curve.
