Who invented the bouncy vinegar egg?

The bouncy vinegar egg, often created as a science experiment, is not attributed to a single inventor but rather is a demonstration of a chemical reaction that has been known for many years. The process involves soaking a raw egg in vinegar, which causes the calcium carbonate shell to dissolve, leaving behind the flexible membrane. This experiment has been popular in educational settings to illustrate concepts like osmosis and chemical reactions. While the exact origin of the experiment is unclear, it has been widely shared and popularized in classrooms and online.
