Small Science Experiment (15) "Flying" Paper Cup

Lingbao city No.1 primary school

Zhao, grade 63

Can paper cups fly? That's impossible, right? However, I do have a way to make two paper cups fly away from each other.

I'm in a hurry to do the experiment and wait for my mother to take pictures.

Experimental treasure chest: two paper cups.

Experimental operation:

1, put two paper cups together.

2. Hold the paper cup in your hand.

3. Blow hard into the joint of the paper cups, and the two paper cups will move away quickly.

I put two paper cups together and blew them slowly. They seemed to be filled with stones and did not move. I tried several times, but it still didn't work. I held my horses and patiently tried again. This time, I used a little more effort than last time. I found that the paper cup on it rose slowly and suddenly went back. I was angry when I almost succeeded. I blew hard, but I didn't expect the cup to fly into the camera. Many things happen, and the experiment finally succeeded!

The paper cup rises slowly

Paper cups just can't "fly"

Paper cups finally "fly"

The experiment was successful.

From the unsuccessful experiment to the final success, it turned out that the strength was not well controlled. After summing up my experience, I happily put three paper cups together and blew them with greater strength. The paper cups "flew" in the air and succeeded again. Excited, I added one or two more, and the more I blew, the harder I tried. Every time I experimented, the paper cups could "fly". How interesting! All the experiments were successful.

Three paper cups nested together can also "fly".

Look at this paper cup, it flies in front of you!

When I was happy, I asked my mother to try it. My mother really didn't "enlighten" and gave it a try.

N times are unsuccessful. I told her about the blowing experience, and finally the paper cup could "fly", but unfortunately I didn't capture it because I was looking at the photo. So, I said to my mother helplessly, "Hey! Mom, you are too photogenic! " The experiment ended after mom failed n times and succeeded n times.

Mother also took part in the experiment.

After mother experimented n times, the paper cup "flew".

Why can paper cups "fly"? I found the scientific principle of this experiment from the internet: it turns out that when we blow air into the joint of two paper cups, the blown air will replace the air in the gap where the paper cups overlap, and at the same time, it will produce a kind of pressure, forcing the inner paper cups to jump off automatically under this extrusion. Oh! The pressure makes the paper cup "fly".

"Flying" paper cup

I know another scientific knowledge. It's great to do scientific experiments. Not only fun, but also learning knowledge. Let's do it together (sorry, I've said this for n times)!

Mom has something to say:

This experiment is particularly interesting. When my son is doing an experiment, it will be OK if he tries it once or twice. He tried tirelessly, experimenting again and again, increasing difficulty and experience. I, a master photographer, was busy capturing the lens, so I had the wonderful moment above.

As a result, I was involved. At first, my son was very happy because he failed several times because he didn't master the essentials of the experiment. After mastering the secret of the experiment, I won many victories. It's a pity that my son, the master photographer, didn't capture it, leaving only the paper cup that began to rest after "flying". However, we enjoy it.
