What you need: 1 egg 1 cup vinegar clear jar or glass Directions: Pour 1 cup of vinegar into jar Add the egg Record what you see (bubbles rising from the egg) Leave the egg in the vinegar for one day. Remove the egg and feel it. Record your observations (the egg shell will be soft) What happened: Eggs contain something called "calcium carbonate". This is what makes them hard. Vinegar is an acid known as acetic acid. When calcium carbonate (the egg) and acetic acid (the vinegar) combine, a chemical reaction takes place and carbon dioxide (a gas) is released. https://www.facebook.com/Qetz-Insight-572573706747965/https://www.youtube.com/watch?v=u89snta1Q5Y&t=11s
