Disappearing Egg Activity for Kids- This egg experiment is a great letter

This egg experiment is a great letter “E” activity for preschoolers and a fun science activity for older kids! If you are using this Disappearing Egg Activity for Kids with older elementary kids, here is some background. The egg dissolves because egg shells contain calcium carbonate, the main ingredient in many antacid tablets. This dissolves in the acidic vinegar to produce calcium ions (which stay dissolved in the vinegar) and carbon dioxide gas. The carbon dioxide produces the bubbles that you will see while the egg is dissolving. Now that you know the science behind this cool activity, here is everything your kids need to give it a try!
