Orangutans (great apes that live in Sumatra and Borneo) use umbrellas! They pluck big leaves off the trees and hold them over their heads to protect themselves from heavy rainfall.
The Spinners
The Spinners A spider's secret could revolutionize the chemical
industry by introducing new, eco- friendly techniques. The way
spiders make the silk fibres of their webs is what interests
Christopher Viney, a chemist at Heriot-Watt University in
Edinburgh. A spider's silk is one of the strongest materials on
Earth. Understanding how spiders make their silk could help
industry to use more natural techniques. Strong manmade fibres are
usually made under conditions which use many chemicals. However,
spiders make their silk by using nothing more than protein and
water. The more researchers learn about the spider's silk they more
they marvel at the spider's secrets. One day they hope to unravel
the mystery of spider silk and learn how to make similar materials
which will be stronger than any yet made. 24 APRIL 1999, P. 39-41
