We asked ourselves the question, “Can you make an egg bounce?”
Hypothesis: (guess) We made a guess and discussed what we thought would happen.
Day 1: First we put an egg in a glass (not boiled).Then we covered it in vinegar (someof us added food colouring to this).
Day 2: Empty the vinegar and put fresh vinegar in.
Day 3: Touch the egg. How does it feel? Don't empty the vinegar.
Day 4: Empty vinegar and put fresh vinegar in.
Day 5: Don't empty the vinegar.
Day 6: Empty the vinegar and put fresh vinegar in.
Day 7: Tip out the egg out of the glass. Has it got a shell? What has it got around it?
It made the bounce when you dropped it instead of breaking. Remember to bounce it just a little because it is just the skin that is holding it.
Conclusion: The vinegar removes the shell but leaves the membrane or skin. The water stretches the membrane which is thick and can be shown to students. This allows the egg to “bounce.”
WE LOVED doing this so much so that we are going to continue to do
some more egg experiments. Stay tuned for more!

Hello Mrs C-B and Shanae S,
I enjoyed doing the experiment. The shell got softer until the egg felt like rubber. I put green colour in with mine so the egg turned green too.
