Everyone often hears about insects, which are the ancient times in the natural textbooks of the primary school. The turpentines flow down to wrap the insects and eventually become fossils. When I saw a mosquito amber, I suddenly thought of a question. Why did the thick turpentine fall on the mosquito without bending its wings to wrap it? The mosquito's wings don't have the power to keep it stiff in the thick, thick turpentine? ! In fact, this is because the resin is not so thick when the mosquitoes are wrapped in. Resin, the product of physiological activity of trees, consists mainly of terpenoids. The freshly discharged turpentine is a colorless and transparent oily liquid which, when exposed to the air, becomes thicker as the oxime is vaporized, and finally becomes a white or yellow solid substance. First of all, the turpentine that has just been dripped is not too viscous. Secondly, the insect body has a natural resting state, just like a human hand will show a natural micro-grip state when it is not working. That is to say, it is necessary to change this state, and to maintain this state, it can be considered that no force is needed. The liquid is not a rigid body, and the viscosity can only affect the difficulty of changing the movement of the object and cannot prevent the movement of the object. As long as the strength of the limb recovery is greater than the maximum static friction, it can continue to move in the viscous turpentine. Therefore, under the action of tiny forces when the insects return to their natural state, as long as there is enough time, they can completely return to the natural state. The insect itself may have died in the process, but this does not affect its recovery posture in the resin. You can find this process by looking for varnish or other slowly solidifying liquid. Moreover, the mosquitoes vibrate five or six hundred times in one second. Although it feels soft to people, it is actually not just a film. After being wrapped, the wings of the mosquitoes can be stretched vigorously, although there is no What to use.
