On Tuesday’s Egg Day, we began a 3-day experiment. We placed a raw egg into a mason jar full of vinegar and sealed the jar, setting the whole thing aside for a few days. At that point, the kids hypothesized that the egg would explode inside of the jar.
This morning, we had a look at our egg to see if it had transformed.
When Bea went to unscrew the lid, the jar made a popping sound, as if gasses had been released. Aside from the strong smell of vinegar, however, we didn’t sense any off-putting smells.
Each of the kids had a turn trying to remove the egg from the jar. This was difficult. The egg had expanded. And, it looked even larger than its new, expanded size because of the presence of the liquid. It also seemed rather squishy. I finally had to remove it with a large spoon.
The kids were amazed by the results! They were left with a bouncy, rubbery chicken egg the size of a goose egg. It had an orange tinge from the yolk still trapped inside.
They spent some time squishing it, but neither of them wanted to bounce the egg to see if it would break. So, we wished it well and deposited it back into the jar of vinegar for safekeeping. We might break it out again at Halloween, perhaps transforming it into a “floating eye” for display by the cauldron of candy we keep at the front door! Come “trick-or-treat” at our place and you can have a look!
