I succeeded

Once the teacher left us a special assignment - let us use waste items to make a work with technological content.

I thought about it again and again and decided to "build a boat". When I got home, I found scrap foam plastic to make the hull of the boat, old toothpicks to replace steel nails, the windows to be painted with blue ink, and the small red flags to be made from the labels of arowana oil. Everything is in line with the principle of waste utilization. A catamaran passenger ship was finally built.

I happily put the boat into the pool. To my dismay, it floated on the water but remained motionless. How can I make it travel? I thought hard about it for a while. Suddenly his eyes lit up. One day not long ago, I was playing with several soap boxes in the bathtub as a boat, and suddenly I found that one soap box was moving, but the other soap boxes were floating there motionless. I was very curious, so I picked it up and took a look and found a small piece of soap stuck under it. I thought: Could this little piece of soap be working? Yes, why not give it a try? I cut off a piece of soap with a knife and stuck it on the bottom of the boat, but I didn't see the boat move. Huh? Why doesn't it work? Oh, maybe it's glued in the wrong place? I readjusted it several times, but it still didn't move. At this time, I was a little frustrated. I thought forget it. Just at the moment when I was about to give up, "I had to think over and over again for several months. Ninety-nine times I came to the wrong conclusion, but the hundredth time I was right." Einstein's famous saying stuck with me. It echoed in my ears for a long time. yes! How can you give up doing something halfway? I cheered up again and tried again and again. Finally I dug a groove under the waterline at the stern and stuck a small piece of soap on it. When the boat took on water again, wow! I saw it driving straight ahead slowly.

Looking at the moving boat, I murmured to myself: "Why can soap make the boat move?" My dad heard it and he patiently explained: "It's because the surface tension of soap is greater than It’s because of the water.” It dawned on me.

Through this experiment, I finally understood a truth: only by boldly trying can you achieve success.
