Silkworms are caterpillars that grow up into silkmoths. They live almost entirely on mulberry leaves. The cocoon they make can be used to make silk, a very attractive cloth that has been valued for thousands of years. A silkworm cocoon is made from a single strand of silk 1000 to 3000 feet long, and it takes 2000-3000 cocoons to make a pound of silk. The caterpillar in the cocoon is not allowed to emerge by itself, as this would damage the silk. The cocoons are boiled with the caterpillar inside.
A silo is a large cylindrical structure for storing a large amount of something. Silos are most often seen near farms for storing grain, but can also be used to store coal, wood chips or even missiles.

Silver is a soft, shiny metal that can be polished to be highly reflective. It tarnishes easily, however. Silver is very conductive and today is used electrical components. Silver is widely used for making jewellery, and was used for making tableware like knives and fork. As pure silver is so soft, most practical items made from silver are made from an alloy of silver and another metal like copper.
