　　"If you want to see a thing well, reach out and touch it!"

　　That may seem a strange thing to say. But touching things can help you to see

them better.

　　Your eyes can tell you that a glass ball is round. But by holding it in your

hands, you can feel how smooth and cool the balls are; You can feel how, heavy

the glass is.

　　When you feel all these about the ball, you really see it.

　　With your skin, you can feel better. For example, your fingers can tell the

difference between two coins in your pocket. You can feel a little drop of water

on the back of your hand, too.

　You can even feel sounds against your skin, Have you ever wanted to know

why some people like very loud music? They must like to feel the sounds of

music.

　　All children soon learn what "don't touch!" means. They hear it often. Yet

most of us keep on touching things as we grow up. In shops, we touch things we

might buy such as food, clothes and so on. To see something well we have to

touch it.

　　The bottoms of our feet can feel things, too. You know his when you walk

on warm sand, cool grass or a hard floor. All feel different under your feet.

　　There are ways of learning to see well by feeling. One way is to close your

eyes and try to feel everything that is touching your skin. Feel the shoes on your

feet, the clothes on your body, the air on your skin. At first, it is not easy to feel

these things. You are too used to them!

　　Most museums are just for looking. But today some museums have some

things to touch. Their signs say "Do touch!" There you can feel everything on

show.
