Did you know eggs could bounce? Challenge your children to see if they can bounce an egg without its shell. If you place a fresh uncooked egg in vinegar for 24 hrs then its shell will dissolve. You may need to change the vinegar a couple of times and give it gentle rub at the end to remove any stray pieces of shell. Then you should be able to gentle drop the egg from a low height on a table and see it bounce. It’s a novel way to look at dissolving and also the children to see inside an egg before it is cracked opened. Lots of observation over time and exploration into different types of eggs opportunities in this simple but eggciting challenge.
