Here's a fun science experiment, that we tried this week...
HOW TO REMOVE AN EGGSHELL FROM AN UNCOOKED EGG:
Take an uncooked egg, put it in a ziplock bag, add 16 oz. white vinegar. See the carbon dioxide bubbles? Just like in soda pop! The acid in the vinegar is dissolving the calcium of the eggshell...tuck the baggy in a glass...this way the egg will be submerged in the vinegar...wait two days and all you'll have left is a water-balloon type egg....you can feel and see the membrane and yolk!
HOW TO SHRINK THE EGG:
Gently empty the ziplock baggy and rinse it out....drop the egg back in the bag and cover the egg with enough clear corn syrup...tuck it back into your glass.... watch it for 5 days and you'll see the egg shrinking! The liquid inside the egg is slowly coming out and the syrup is not going in!
*You know, after seeing what vinegar can do...I mean completely dissolve an entire eggshell....makes me rethink my choice of vinegar and oil salad dressing? |

I'll have to try this with my boys; they'd love it. They are always doing their own experiments. They make a big mess of my kitchen, but they have fun and they learn so it's all worth it. :)
