Introduction: In the experiment “White Before Your Eyes” four various white powders were experimented on using various liquids (baking soda, cornstarch, sugar and a mystery powder). The purpose of this experiment was to discover what powder/mixture of powders the substance was. Cornstarch was the next powder experiment on. Cornstarch is a white, soft powder generally used as a thickening agent in liquid-based foods such as soups or sauces. When mixed with lower temperature liquids, it forms a past/slurry. As the starch is heated, the molecular chains unravel, allowing them to collide with other starch chains to form a mesh, thickening the liquid (Starch gelatinization). When mixed with a fluid, cornstarch can make a non-Newtonian fluid, for example, adding water creates Oobleck while adding oil creates an Electro rheological fluid (a suspension of extremely fine non-conducting particles which can be up to 50 micrometers in diameter) (Cornstarch). Sugar was the next powder experimented on. “Sucrose is a sugar, the organic compound commonly known as table sugar, cane sugar, beet sugar or, usually, just sugar. Saccharose is an obsolete name for sugars in general, especially sucrose. A white, odorless, crystalline powder with a sweet taste, it is best known for its role in food. The molecule is a disaccharide composed of the monosaccharide glucose and fructose with the molecular formula C12H22O11 (Sucrose).” Baking soda was the last powder experimented on. Baking soda is a
