Speaking of water faucets, now that every family has installed them, everyone must think that they are ordinary and ordinary. However, what I want to introduce to you here is not a halter made of metal materials used for general water discharge, but a water faucet designed and made by myself that is both simple and contains scientific principles. There's another story!

It was when I was in the third grade of elementary school, and by chance, I was playing with a discarded plastic bottle and found it by accident. Let me show you how amazing it is. 1. Production method The production process of the water faucet is quite simple, please do it with me.

First, find an empty plastic bottle of suitable size for beverages, such as Wahaha or Nongfu Spring, and use a small awl to make one or several small holes in the bottom of the bottle, so that the "water tap" is made. However, it is important to note that the hole must be of the appropriate size and try not to be too large or too small. Now, let's pour the water into the bottle, half a bottle or a full bottle, and tighten the cap, does the water not come out?

If the water comes out, it means that the hole is too big. But it doesn't matter if you can do it again, so you can try it a few times and it will be successful. Now, let's unscrew the cap slowly, remembering that it must be slow, not all at once.

If you look at this phenomenon, you will see that the water flows out of the bottle like a trickle, and then you tighten the cap and the water stops. I guess everyone is full of doubts like me! 2. The principle of production With doubts, I consulted my father, who taught "Science" in middle school, and finally understood the truth.

It turns out that the "water tap" is the principle of atmospheric pressure. Atmospheric pressure is everywhere, but we don't usually feel it. In the above production, when we tighten the cap, the atmosphere above the bottle cannot enter, and the atmosphere below holds the water through small holes, and the water cannot come down.

Once the cap is opened, the atmospheric pressure above and below cancels out, and since water also has weight, the water goes down naturally. 3. Regarding the use of the "water faucet" I made, although it is not an invention or creation, I think it can be used in the following places, such as feeding patients and watering bonsai. Please help me come up with more and better solutions.

Fourth, the production experience Through this small production, I feel that not only exercised my hands-on ability, but also broadened my thinking, and more importantly, enriched our primary school life, why not? Students, please pay more attention to the phenomena around us, because science is all around us!
