It’s rubber! The rubber tree’s sap (latex) is made into balloons, hoses, gloves, and more! Watch how balloons are made!

Since bamboo is so bendy, you can make a house with lots of curves--like this bamboo house in Bali, Indonesia!

People let the white things rot and dry out, which turns them brown. Then they’re ground up and made into…chocolate!

Chocolate isn’t sweet unless sugar has been added. In fact, “raw” chocolate taste bitter! These kids are trying some without sugar.
