Regular readers know that I love to make my kids do science experiments as afternoon projects.
I received a couple of great Halloween experiments for kids from Karen Navarre who writes The Bullseye View blog for Target. Her experiments originated at the Kitchen Pantry Blog, which lists hundreds of great experiments for kids.
We've done the non-Newtonian liquid a few times and finding Borax in the store is just too much effort, but the Spooky Eggs looked right up my alley. We have eggs and vinegar and Karo syrup just laying around so I immediately went home and got the kids started.
First, we put 9 eggs carefully into a giant pickle jar. Covered them with vinegar and waited. This was another reason this was such a great experiment because it took me all of 5 minutes to do it.
The eggs immediately started provide the kids with a great show as they started to float and bubble and sink.
The next day, I took them out and let the kids handle them a little. Soren and Jonas broke two, but learned that only the shell had disinegrated and the guts were still intact.
I, of course, made them take scientific notes about our experiement along the way.
The next day, we dumped out the vinegar and poured in 1 1/2 bottles of Karo syrup. We probably could have used more but that's all we had. We also added neon green food coloring which created a really disgusting colored slime.
The syrup sucks the water out of the eggs and turns the whites transparent, leaving a yellow yolk floating inside a wrinkly green orb. We were sure to include a warning label so that nobody inadvertantly mistook the eggs for cinnamon rolls.
I told the boys they could take the eggs out and touch them again, but they won't. They are too sicked-out now, but they love it!
Thanks Target for the great experiment. I hope to read more from the Kitchen Pantry Scientist and I can't wait to try more of the experiements soon.
