Researchers know one of nature's big secrets. They found out how spiders make strong silk. It is stronger than steel. Scientists found that the place the spider keeps its silk has a special acid. This makes the silk strong. The researchers copied this. They made enough spider silk to stretch for one kilometer.
The new silk could be very useful. Doctors think it can help with stitches, burns and ligament damage. Airplane companies and clothes companies want it. A researcher said: "This is the first successful example of [copying] spider silk spinning….This may allow…production of…silk for bio-materials."
