At the end of last week we decided to start soaking an egg in vinegar to see if it would bounce. I remember doing this in highschool and probably a few other times as well, but have never attempted it with my kids. So, we got us a glass jar so we could watch the egg each day. We couldn't see any changes just by looking at it. It looked the same, day after day. After several long days of hearing, "Mom, is the egg ready?" and "Is the egg ready to bounce, yet?" over and over. It was finally time. We were finally able to empty the vinegar and rinse the egg in water. Did it bounce? IT SURE DID! My oldest was completely wowed by the factor that it really bounced. He did not think it would, I mean come on, who woulda thunk an egg could bounce? But it did! It bounced and bounced. We discussed how the egg felt (rubbery and squishy at the same time), why it bounced (the reaction the vinegar caused), etc. He played with that joker for over 20 minutes before I had to send him outside with it. (The vinegar smell was horrific) Which once he took it outside it didn't bounce for long, especially considering he threw it up against a tree. A very fun experiment, minus the waiting.
We have also done the whole suck an egg into a bottle thing, which he found fascinating as well. I do advise to have more than one egg ready when attempting that neat little trick though. Our egg broke apart while being sucked into the bottle, so he didn't get to see the full effect. So we will be boiling more eggs to attempt this one again, very soon.
Homeschooling=Amazing. You can do anything at any given time you please. Love it!
