I watched another How it's made video. This one was about Tofu. 

First, the workers put the soybean into a tank filled with water to soak them for 18 to 24 hours so that the soybeans would get bigger than it was before. After the soaking, they dumped the soybean into a crusher to srush them, before using a pressure machine to push the crushed soybean in to a tank through a wire net that keeps most of the soybean on top and sqeezes the water into the tank below. The tank then would start to spin and that would sperate most of the water and the crunches in the water. The left over crunches and soybeans would be transfered into pet food. The water then gets mixed with other materials to make it form its shape. Then, the workers heat up the mixed water and gets a mixed pile of tofu. They soon put the tofu into triangular containers and put pressure onto the container to form the tofu's shape. They cut the tofu into little pieces before sending them into a heater to heat them up and use cool water to cool them down. At last, the tofu would be packaged and ready to be sold.
