The red and black substance is rubber.
How it’s Made First they start out with a small cork. Then they pour a latex adhesive into a drum. Next they loop ply wool around the cork. After that they put another layer of wool on. Then they put a 3 rd layer on. Last they put a wool on that is much lighter. It takes a week to make a MLB baseball!
