We live in the world full of colours. Does a colour have weight? If you say “no”, you are wrong. If you don’t believe, you may do an experiment.

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 woth a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you think the red one is a little heavier.

Why? A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he found that every colour has its own weight in our mind and their order is the same. The heaviest colour is red, then blue, green, orange, yellow and white.

The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wavelength, and it reaches our brain through sense organs.

According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpapers 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. Another example, if a person walks out of a red room and into a blue room, his tempertature will fall. That means our body temperature will change with different colours.

Being safe in your everyday life needs knowledge. If you remember the following information, your life will be much safer.

●Always notice the environment around you. You shouldn't walk alone outside. Make sure where the public phones are. If anything dangerous happens, you can find them easily.

●Your bag should be carried towards the front of your body instead of putting on your back. When a bus is full of people, it is easy enough for a thief to take away the things in the bag on your back.

●If you are followed by someone you don't know, cross the street and go to the other way, let the person understand that you know he or she is after you. Next, don't go home at once. You are safer in the street than you are alone in your home or in a lift (电梯).

●If you have to take a bus to a place far away, try to get to the stop a few minutes earlier before the bus leaves. This stops other people from studying you. On the bus, don't sit alone. Sit behind the driver or with other people. Don't sleep.
