How-To Video: Bouncy Vinegar Eggs

In this cool project, we make an egg shell disappear, revealing what’s inside and creating a bouncy oval object. Our collaboration video with Amy Poehler's Smart Girls demonstrates how vinegar (which contains acetic acid) reacts with the high calcium content of the eggshell and dissolves it! We loved getting to work with their whole team to create eight more videos –including this one on bouncy vinegar eggs – that you can try at home!
