Carver invented all kinds of things made out of peanuts. He wrote down more than 300 uses for peanuts, including peanut milk, peanut paper, and peanut soap. Carver thought that if farmers started making things out of peanuts, they'd have to buy fewer things and would be more self-sufficient. And if other people started making things out of peanuts, they would want to buy the extra peanuts, so the farmers would make more money. Although not many of Carver's peanut products were ever mass-produced, he did help spread the word about peanuts.
