Amazing Egg Experiments | Part 1
Roll your pant legs up and get ready to get your feet dirty! Well, hopefully not, but let’s take precautions. We recently tried some EGGciting science experiments that had us asking all kinds of questions; including but not limited to, “HOW IS THAT POSSIBLE?!”
We’re quickly approaching the Easter season which means you’ll probably have a few dozen eggs sitting in your fridge. Before you hard boil and dye them, there’s more fun to be had with those eggs! We purchased 5 dozen eggs for these experiments and by the time we were done, well still had a little over 4 dozen eggs left (in case you’re trying to plan ahead).
In the following two experiments, we explored how strong AND delicate an egg shell can be – depending upon the scenarios, both statements can be true.
Remember, after working with raw eggs it’s important to clean up, wash your hands and disinfect the area after you’re done!
Egg Experiment 1: Walking on Eggs
Nature has a funny and beautiful way of building protection into design. The arch shape of the egg makes it an amazingly strong structure because stress is distributed equally along the line instead at one point. So obviously, that all just means we had to try walking on them. Yes, literally, we “walked on eggshells” and the end result was not as messy as you may think.
For this experiment you’ll need 4-5 dozen eggs. Begin by laying down an old towel or garbage bag… or don’t… your choice. Position the eggs so that all the “pointy” ends are facing the same way (either up or down). Next, align the egg cartons in a pattern suitable for walking upon. Use your judgment on how far apart or close together they should be depending upon the stride of the egg-walker (<– that’s a technical term). Place your foot, sans shoe, on top of the eggs making sure to distribute your weight evenly. The eggs may shift slightly so don’t be alarmed. Place your other foot on the next carton in the same manner. Continue until you’ve ventured across the entire egg bridge.
When we were done, we actually had cracked 2 eggs. My son, Ryan, was a little hesitant (I can’t imagine why) which caused his weight to be distributed mostly on his heel. He weighs about 55lbs. I took a walk over the eggs myself and didn’t crack one. I won’t reveal my weight but I will say it’s significantly more than 55lbs.
All kidding aside, this was a super fun experiment that was a true testament to mother nature and her design!
Egg Experiment 2: Snake Eggs
Unlike birds, snakes lay their eggs underground for protection and for incubation. Depending on the type of snake, their eggs can be soft and leathery to the touch. We made fake snake eggs by dissolving the outer shell of regular eggs in vinegar. Vinegar contains acid that breaks apart the eggshell. Because the yolk/egg white is left just in the outer membrane, it’s bouncy and soft to the touch.
Here’s how we did it: We filled three glasses up with vinegar and placed the eggs gently inside. Then, we waited… and waited… and waited. We waited for about 24 hours until the shells were completely dissolved. There was a white foam at the top of the glass and the egg had a yellow tint to it. We took the egg out of the glass and washed it off carefully. The hard outer shell was gone and the egg was left only with a soft outer membrane. In fact, when the egg was dropped it bounced! We also tried shining a light behind the egg to see if we could see the yolk but I don’t think our flashlight was strong enough. Nonetheless, it still made for a really cool effect.
