The Incredible Naked Bouncing Egg

WE LOVE SCIENCE!! And seriously, who doesn't?! I remember being young and when my neighbors, my brother and I would find ourselves with nothing to do, we would scour the kitchen cabinets looking for things to dump in a bowl and called it a potion. It usually ended with the girls daring the boys to taste test whatever we had concocted, which ultimately led to a "burial" in which said concoction was poured in a hold we had dug in the back yard. Well, these days it's really no different with my own kids :) Busy and the Beans will make potions and experiment using anything they can find in the kitchen!! Which leads us to yesterday. They asked if they could hard boil an egg to see if it bounced. Great idea, right?! So in the name of science, we tried it.




















As it turns out, hard boiled eggs don't bounce all that well ;)

But like many times before, this gave me another idea to explore. I remembered seeing another egg experiment all over Pinterest about dissolving the shell off an egg using vinegar. So to keep in the theme of eggs, we decided to give it a try :)

What You Need:

  • An egg
  • Vinegar
  • A cup or bowl deep enough to cover the egg completely
What To Do:
  1. Put the egg in the cup and pour enough vinegar in the cup to cover the egg completely.
  2. Wait. *You need to wait about 48 hours for the shell to dissolve completely.
  3. Once the shell has dissolved, since off the goop and start bouncing! *Not too high of a drop! It could pop!
For this experiment, like most science experiments we do, I had Busy write their predictions about what would happen to the egg in their science journal. Beans thought it might explode and Busy predicted that it would get soft. After the experiment was complete, we discussed their original predictions and although Busy was right, she did say that she was not expecting the shell to come off. She thought the shell would just get softer. Then after a couple of days of coming back again and again to play with the soft naked egg, the Beans asked if he could pop it. So armed with a toothpick, he jabbed his way through the membrane to expose the yolk! All in the name of science ;)

Marbled Paper

The other day the kids were painting in the art room and Busy asked if she could paint "scientifically." I asked her what that meant and she said she wasn't quite sure what she meant, only that she wanted to try an experiment that incorporated science into painting. She began by mixing water, glitter glue, cut up fuzzies from a sparkly pipe cleaner, liquid water color and white glue. She then dipped torn pieces of white paper into the concoction until they were soggy but not falling apart, and placed or "painted" them on to a small canvas. The result was exactly what she had pictured in her own head so she was more than pleased with herself :)

This process of paper and paint and goop got me thinking about how we could use paper to dip paint and achieve a rainbow type of result. Turns out there are some super smart moms in the blog world who have already done this exact type of thing! Ana at Babble Dabble Do is one of them. She calls it "marbled milk paper" and the result is quite stunning! (She has a video tutorial, so pop over there to see this in action.) Without showing the kids what was going to happen, we tried our own :)

What You Need:

  • almond milk
  • food coloring
  • toothpick
  • liquid dish soap
  • watercolor paper or card stock (regular paper doesn't soak up the color enough)
  • a shallow tray (like a cookie sheet or pyrex pan)
What To Do:
  1. Cut the paper to fit your tray.
  2. Pour enough milk in the tray to cover the bottom with a thin layer of milk. 
  3. Add drops of food coloring all around the milk layer. 
  4. Add drops of dish soap next to your food coloring drops.
  5. Swirl the colors around using the toothpicks (don't mix them too much)
  6. Take a sheet of paper and lay it on top of the milk and colors gently pressing down. 
  7. Carefully lift the paper out of the milk and set it aside to dry. Continue with other sheets of paper and notice that no two marbled designs are the same! Once the colors get too muddled or aren't bright anymore, simply dump out the tray and start over!! 











The kids had a blast with this project! Once the papers had dried completely, the post on Babble Dabble Do suggested that we place them between sheets of paper and iron them flat, so we did. Instead of hanging them on our gallery wall, Busy decided that she wanted to use them to write letters to her grandparents :) xoxo 

What will you do with your marbled paper?!


And this was the inspiration...
