The girls nerded out this year and did their school science fair project together. The best part? They did it TOGETHER which was awesome. Tink is in fourth grade and Pink in sixth, so I was worried they might want to do their own separate thing. But they were excited. Which meant less stress for me!
Their project, which they did 100% on their own (with the exception of me buying the supplies) was to show how a raw egg can bounce. You can actually do this quite easily at home. Just soak an egg in white vinegar for 1-2 days until the shell is dissolved. Then, run it under water and gently rub off the white part that is under the shell. You will then see this transparent membrane and the yolk inside.
And, you will be able to BOUNCE the egg with a gentle drop of a few inches. (It's not a super ball and so don't like throw it on the ground expecting it to bounce like that.)
The "experiment" part was to try different types of vinegar and see what differences there were. They tried Rice Vinegar, Red Wine Vinegar, Balsamic, and Apple Cider Vinegar. They had some interesting results. Try it!
It was really neat to see all of the projects and the kids seemed to have a great time. It made a busy week even busier, but it was definitely worth it.
