Answer 1

1. Natural rubber is made from a runny, milky white liquid called latex that oozes from certain plants when you cut into them.

2. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (Hevea brasiliensis) or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping".

3. The work is done at night or in the early morning before the day's temperature rises, so the latex will drip longer before coagulating and sealing the cut. Depending on the final product, additional chemicals can be added to the latex cup to preserve the latex longer.
