Hovercraft, also known as "spaceship", is a kind of ship that rises out of the water with the support of air. As soon as this kind of ship appeared, it immediately attracted the attention of shipbuilding industry all over the world.

Three days ago, the teacher asked us to make hovercraft. I cheerfully took out the materials for making hovercraft: CD, 10 1 glue, balloon, bottle cap and straw, and began to prepare for making hovercraft. I couldn't do it at first, but many students in our class did well, so I decided to give it a try.

All the students in my class do the same thing, but why do some run far, some run close, some run fast and some run slowly? I started to operate while thinking about these problems. At first, it didn't go well, and even the bottle cap couldn't stick to the CD, so I asked my mother for help. The bottle cap finally stuck, right in the middle of the CD, and I looked very satisfied. The next step was to drill a small hole in the bottle cap with a needle, but I wouldn't use force, and my hand was punctured at once, but I endured the pain and continued to work, and the small hole was finally tied. Then I put the balloon on it and finally finished it. Although it doesn't look good, I'm very excited now, because I made it by hand. Next, I'm nervous because I'm going to try. Can I succeed? Try it anyway! I used a straw to blow into the bottle cap, then took the straw away and put it on the table. As soon as I let go, the hovercraft ran away and finally succeeded. Although my hovercraft is not as good as a real hovercraft, it is also a regular hovercraft, so I am very proud.

I like science more through the small technology of hovercraft, so I will study harder and become a successful scientist in the future.
