First, put some sugar into a rotating pot by centrifugal force. This small pot should be able to rotate, and there should be many holes on the side. It's about the size of a fist, and there must be a cauldron several times larger around it. Then you can heat the small pot in the middle and turn the small pot as big as this fist by hand or hand. In this way, the sugar will become a solution after heating, and then it will be sprayed to the periphery of the cauldron (from the hole on the side of the cauldron) at a high speed. When the hot sugar solution cools, it immediately becomes a white ball, which is how to make marshmallows.
But some marshmallows are not only white, but also have many colors. This is because the sugar it uses is colored, so you can have any color you want.
