An unopened can of soda feels very solid because more than three volumes of dissolved carbon dioxide gas create a pressure of about 55 PSI above the liquid. This is about four times atmospheric pressure. Fill a baby bottle with soda, secure with a rubber nipple without a 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. Includes baby bottle, two rubber nipples without holes, and instructions. Designs may vary.
