There's much to see under the sea, but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out to touch something and completely missing it.

Objects under water will appear larger than they would on the surface, too. Be careful not to tell any stories about the big fish that got away. That fish might not be so big after all! It's just because sometimes things can seem to be as much as about 33 percent bigger in water!

What's more, in deeper water, colors just don't seem as bright. In fact, it looks as if some colors are missing. Remember the color of an object results from the wavelengths(波长) of light that are reflected(反射) from its surface. And light is taken in as it moves down through the water.

Swimmers wear wet suits to keep warm underwater. Let's take a bright red, yellow, and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in the water. The red part now looks almost black because the red light wavelengths, the longest among these three colors, are missing. As you go down deeper, the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater, you will look terrible, like a ghost(鬼怪)! And you have to wait for your return to the surface to enjoy the bright colors again!

Scientists have always believed that snails are not able to find their way home. But Briton Ruth Brooks, a retired teacher, has found that it is not true.

Brooks started working on snails after she got angry with the snails in her garden. The snails ate her vegetables. She didn't want to kill them, so she took them to another place. But she found they always seemed to come back. Brooks tried to mark the snails in her garden with nail polish (指甲油). She placed the snails in the place around her home and made notes of their movements. She found that snails have a strong homing instinct (本能); the longest returning snail traveled back 90 meters.

People started to call Brooks Britain's best amateur (业余的) scientist after her work won the BBC's prize “To Be A Scientist”. She said, “I've always wanted to know whether the snails that eat my plants just come back when I move them, and if they do, how far is it from their home?” "I would say on the evidence (证据) that it would be safe to take your snails away 100 meters or even farther. If you put them somewhere nice with some food, you can be almost sure that they won't come back."
