The egg that didn't bounce

As with everything else academic this term, science has gone truly "experimental" in our new interest-led approach.  First of all, Tiger has been reading many books on his own absorbing a fair bit of general science knowledge:

When Tiger came across something that looked interesting, we carried out an investigation:

The instructions for the "bouncing eggs" experiment were simple enough.  Just soak an egg in vinegar for 24 hours, then it is supposed to be able to bounce.

3 minutes into the experiment.
24 hours later.
We took the egg out and dropped it gently on the floor....

It didn't work!!!  How annoying!  After we got past the initial shock of the unexpected result, we found the reason why from this website that has a more detailed and clearer explanation to the same experiment: the egg has to be left in the vinegar for 72 hours or longer, until the outer shell has been totally dissolved.  Wrong instructions from the initial book, then.

  1. Bouncing cool! Thanks for linking up with "Its A Wrap."

  2. Wow! Are you going to repeat the experiment? I may have to try that one. Thanks for sharing!

  3. I never got mine to bounce either as they were too fragile without the shell and just the membrane left.

  4. Love all the books you shared, and especially the reason why it didn't work. I so appreciate you including this in the post, very helpful. Thank you for sharing.

  5. We have science experiments like that too!!! We may give this one a try too, just for something fun to do. Thanks! Visiting from Favorite Resource of the Week!

  6. That's a bummer! I hope it works for you next time. We tried this experiment before but not for the bounce. We'll have to try it again. Thanks for the idea.

  7. Ugh, how annoying is right! The good part, in my opinion, is that Tiger is reading about science on his own because he is interested in it, and is finding activities to do...unfortunately, sometimes they don't work. Better luck next time?
    Thanks for linking at Favorite Resources :)

  8. What a great experiment and at least you now know why it went wrong. Sometimes I complete one and can't ever figure out why our results varied. Thanks for linking up with "its a wrap." I hope you'll return this week.

  9. I'm sorry I had to laugh at the "it didn't bounce," but I understand the frustration. Good for you for persevering!

    Thanks for linking up to Science Sunday!
