Make an uncooked egg bounce! ExpeRiment with different liquids to see what effect they have on eggs. And learn how the acid in household liquids like orange juice and vinegar react with eggshells and make them dissolve, leaving the inside of the egg intact. Olympia and her daughters, Viola and Elodie investigate what effects different liquids have on an egg. They discover that some don’t cause large changes while others make the shell dissolve altogether. In this simple, if a little bit messy, science experiment they learn that although liquids might look the same, they can be very different inside. They see what happens when they drop the egg after they’ve dissolved its shell. Will it bounce?

If you don’t want to use up an egg for this activity, it can be done with just the shell of an egg – simply put pieces of empty egg shell in the liquids and see what happens.

This series of ExpeRimental is supported by the Royal Society of Chemistry.
