Have you ever wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves.
Birds, especially seagulls, are very fond of locusts, but birds cannot easily catch locusts because locusts change their colours together with the change of the colour of crops.When crops are green, locusts look green.But when crops are ripe, locusts take on exactly the same brown colour as crops have.Some other pests with different colours from plants are usually easily found and eaten by their enemies.So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of colouring is to protect themselves.Bears, wolves and other beasts move quietly through forests.They are usually invisible to the eyes of hunters, because they have the colour much like the barks of trees.
An even more strange act remains to be noticed.A kind of fish living in seas can send out a kind of very black liquid when it faces danger.While the liquid spreads over, its enemies cannot find it, and it immediately swims away.Thus, it has existed up to now though it is not powerful at all.

In 1913,an item called the Erector Set was invented. It was a steel,motorized toy that children could use to build models of anything. Its creator was A.C.Gilbert,a medical doctor.

Raggedy Ann dolls first came on the scene after newspaper cartoonist Johnny Gruelle reproduced the doll he made for his daughter. That was in 1915.
