Lesson 9
An Experiment
Guidance
Do you believe a color has weight? And do you think colors also have smell? The following experiment can tell you the truth. 你认为颜色有重量吗？颜色有气味吗？下面的实验会给你答案。
1 There are many colors in nature. But do you think that a color has weight? I think you’ll say “no.” But I am afraid you are wrong. If you don’t believe it, you may do a small experiment.
2 First, put two objects with the same weight into two boxes. Then cover the boxes. Third, wrap one box with a red piece of paper, the other with a white piece of paper.① OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.②
3 Why do you think so? A scientist found that different colors have different weights in a man’s mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind.
4 The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for a kind of light with a certain wavelength.③ It reaches our brain through sense organs.
5 According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or even get ill.④ For example, you like blue and hate red. If you stay in a room with red windows, wallpaper and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. And, if a person walks out of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colors.
