Excellent composition about the experiment: toothpicks love candy.

? Toothpicks like candy, too? I shouted exaggeratedly with a book. How is this possible? Yes, toothpicks are lifeless. How can it eat sugar? But this book is an authoritative work, so it shouldn't be wrong, should it? I thought about it, but I still can't find the answer. No way, we can only do an experiment to verify it.

I put down my book and went to the room to rummage for information. Is this it? No. What about this? Well, not really. Yo, I found it! That's it! The material has finally been found! Ok, now start the experiment!

First look at how to do it in the book: first put a cube of sugar on one side of the water, and then put the toothpick on the other side. Well, I tore the package of sugar cubes three times, five times and twice at once, took out a piece and put it on the water, took a toothpick, set the position according to the book and began to observe. But the result really scared me? The toothpick did not float to the sugar cube as written in the book, but kept swinging from side to side on the water. ? Alas, I seem to have read another book that misleads others' children. ? I stood up and prepared to pour the water. Suddenly, the toothpick wobbled in the direction of the sugar cube, and I couldn't help but stop. After half a minute, the tip of the toothpick touched a few drops of sugar, and then the whole body leaned against the sugar cube. So, toothpicks. Really? Do you like candy? !

Then, the second experiment began. This time, change the sugar cube into soap. With my first experience, I didn't dare to act rashly this time. I just sat there quietly waiting for the result. At first, the toothpick was slowly approaching the soap, which surprised me. I can't help thinking: Do toothpicks still like soap? This is different from what the book says. It's really delicious! Slowly, the toothpick approached the soap and was about to hit it, but it popped out like a spring and ran to the basin. What's going on here?

With this question, I went to consult omniscient? Du Niang? . Where are the toothpicks? Do you like candy? But? Don't like soap Because the density of sugar molecules is lower than that of water molecules, water molecules will drill into sugar molecules, drive tiny water flows and bring toothpicks. The surface tension of water contacted by soap will decrease, resulting in water being covered. Get out? Yes, I pushed the toothpick away, too

This discovery is really interesting! There are many interesting things waiting for me to discover!
