After our visit to Discovery Place, we’ve been in full on ‘science experiment mode’ around here. I’ve been pinning things I wanted to try with the kids for a while, and we did do a cool color mixing experiment a few weeks ago, but Addison has really shown an interest in ‘what can we make things do’ and the weather in the last 3 weeks. We’ve been watching videos of tornadoes and volcanoes, mixing baking soda and vinegar, etc. I found an article on how to make a naked egg (from Imagination Station) and thought she’d find it interesting, so I told her about it and her reaction was ‘I want to do it!’. So, we did. It’s really pretty cool and something that’s so easy and requires so little, you probably have everything you need already. You can see the full video and instructions here.
You start with and egg and some white vinegar. All those little bubbles on the surface are the vinegar at work. The idea is that the vinegar dissolves the shell, leaving the interior membrane intact, thus making your egg ‘naked’.
About 24 hours in, you can clearly see that it’s working.
We went with the videos suggestion and left the egg for another day and ended up with this. It was rubbery and definitely larger than when we started.
I wanted to see if it would suck up any more water, so I grabbed the food coloring and made it a nice, dark blue bath. Another 24 hours, and we had what looked like a nearly black egg.
You can see that the surface still has a texture, but it’s definitely squishy.
The video suggests bouncing the egg. It totally works too. I was able to bounce the egg on the table without a problem, but the girl got a little excited and didn’t follow instructions very well, literally dropping the egg from a good 6-8 inches about the glass and SPLAT!
This actually turned out to be an ok thing. It gave us a chance to check out what happened on the inside. In addition to being able to see the blue food coloring in the contents, it was very clear that the egg was in fact saturated and somewhat watered down. The yolk didn’t take on any of the color, but the whites certainly did.
It was very neat watching the egg change over the course of the three day experiment, and if you have a child interested in science, it’s definitely something to try. Just be sure to clean everything thoroughly, hands and surfaces, to make sure no one ends up sick.
If you try this at home, I’d love to see pictures of your results!
