【 Operation Method and Principle 】 Take a cup filled with water (slightly higher than the base of the bird), place it in front of the bird, so that when the bird lowers its head, the tip of its beak can be immersed in water. At the beginning, soak the bird's beak and head fur, gently flick the bird's body, and let it swing freely. Due to the cooling effect of the water evaporation in the head fur (Note 1), the pressure of the gas in the abdominal cavity is greater than the pressure in the head cavity, causing the liquid to rise and the center of gravity to rise beyond the position of the iron clip. Due to the lever principle, the bird's head will sink into the water, and the water will be introduced into the head through the capillary effect of the mouth (Note 2). At the same time, the liquid in the body will flow back.

Note 1: Evaporative cooling effect: During the process of transforming a liquid into a gas through evaporation, it absorbs heat from the surrounding environment, thereby reducing the surrounding temperature and playing a cooling role; Note 2: Infiltration and non infiltration phenomena. The infiltration or non infiltration of a certain solid depends on the properties of the liquid and solid. For example, water infiltrates glass, while water does not infiltrate lotus leaves. Capillary phenomenon is a manifestation of infiltration characteristics. Infiltration will rise in the thin tube, while non infiltration will decrease.

【 Operation precautions 】 (1) The surrounding environment includes temperature and humidity, with a temperature between 25 ° C and 35 ° C being better; It is basically impossible to swing below 16 degrees (related to the characteristics of the liquid). (2) Adjust the height of the bird iron clip up and down to adjust the center of gravity of the bird; (3) If the bird swings to a certain position and stops or tilts back, it is because the iron clamp is installed upside down, and the iron clamp needs to be rotated 180 degrees (4) Minors under the age of 18 must complete scientific experiments under parental supervision. (5) Any disabled person must complete scientific experiments under family supervision!!! (6) Internal liquids are strictly prohibited from consumption!!!
