Let's talk about birch, it is not afraid of bullets! When a bullet hits an ordinary tree, it will stab a hole in the trunk, but it can't take the birch away, because the wood of birch is hard and thin, twice as hard as ordinary steel! It's amazing that it can be used as a substitute for steel. The bullet hit him, intact. I wonder if this birch can be used to build bulletproof cars. That's great!
Let's talk about the laughing tree again. In a botanical garden in the capital of Rwanda, Africa, there is a tree that can make a "ha ha ha" laugh, so people call it a laughing tree. Why is this? It turns out that there are small bells that can make sounds between its branches. There are many balls in these little bells. As soon as the wind blows, the ball rolls around in the cavity, making a strange sound similar to human laughter.
And that big fat tree. Because I am a little fat, this tree attracts me to know it. It grows on the savanna in Africa, and its "waist circumference" is generally 50 meters. It takes dozens of people to hold hands to get around. In the rainy season, the big fat tree absorbs water desperately, and the fat body is full of water, just like a big bucket. When filled with water, it can produce large white flowers.
Finally, let's talk about turmeric, which is also called "blood-sealing throat" and is a tall evergreen tree. I saw it at Yanoda Botanical Garden in Sanya this summer vacation. Its juice is highly toxic. An arrow stained with the venom of this tree hits the beast, and within a few seconds, the blood of the beast can quickly solidify, and the heart stops beating and dies. If the sap touches a person's wound, he will die immediately. It is very toxic. I dare not touch the bark of this tree. It is too dangerous!
This book also introduces many plants, which makes me know a lot about plants. It is really interesting! Students who want to know can borrow books from me after school, and you will also be attracted by mysterious plants in nature!
