An unopened can of soda feels very solid because of the more than 3 volumes of dissolved carbon dioxide gas creating a pressure of about 55 PSI above the liquid. This is about 4 times atmospheric pressure. Fill a baby bottle with soda, secure with a rubber nipple without hole, and shake. Watch the nipple expand as the gas comes out of solution. Amazing to see! Great for teaching Henry’s Law of Partial Pressures. Compare different types of soda; soda at two different temperatures; etc. Included are two baby bottles, four rubber nipples without holes, and instructions.
