Project Learn and Grow

Bouncing and Shrinking Eggs
Today we experimented with eggs.  I have seen a lot of pins on pinterest about how to make eggs bounce so we had to try it.  
All you need:
  • Eggs
  • Vinegar
  • Corn syrup
  • Water
  • Food Coloring
  • Sugar
We started out soaking the eggs in vinegar for 1-2 days.  We just put the eggs in a bowl and made sure they were covered with water.  We soaked them for 2 days and the eggs shells came right off and dissolved in the vinegar.  Then you can lightly bounce them on the counter top.  You need to be very careful doing this or they will break.  Just the outside is bouncy.  Colin got a little excited and broke a couple of eggs.  
Next we took a bowl of just water and a bowl of water with lots of sugar in it and wanted to see which one floated and which one sank.  The kids loved seeing how the egg floated in the sugar water and the egg sank in just water.  
Then we decided to color the egg that we shrank so we stuck it in a bowl of water and green food coloring.  This just takes 30 minutes to get it a decent color.  Then we put it in the bowl of corn syrup and let it sit for 24 hours.  The next morning it was a shrunken egg.  
To make the egg big and bouncy again we put it into a bowl of water and after 2 hours it was back to it's bouncy size.  
This was really fun for the kids.  They loved seeing how much the egg changed everyday.
