Corn starch was patented by Orlando Jones in 1841. Jones, a British citizen, received US Patent Number 2000A. One of the main uses of corn starch is as a thickener to soups, stews, gravies, and puddings. It also serves as an anti-caking agent. Examples include its addition to confectioner’s sugar and grated cheese. Children could see the patent at: Corn Starch Patent. Corn starch, when added to a liquid, becomes a non-Newtonian fluid, meaning it is a substance that has both characteristics of a liquid and characteristics of a solid.
