This cool experiment for kids called the rubber egg is probably JDaniel’s favorite of all the cool science experiments with egg we have tried this spring. He spent several days observing the egg as it was transformed. He later had a wonderful time watching it bounce.
We started by putting a raw egg into an old glass tomato sauce jar very gently. One of us was a little worried that the egg would crack and ooze the entire inside of the entire jar. One of us had no worries about that happening. I bet you can guess who was worried.
With the egg in the jar we poured white vinegar into the jar until the egg was completely covered. We were surprised to see bubbles form in the water. The egg started to spin a little too. It was really bizarre. When we looked at the egg later that day, the vinegar looked normal and the egg had settled down.
We left the egg in the jar for three days. The vinegar in the jar had strong odor during that period of time. We thought about taking the jar into the garage, but ended up putting a lid on the jar instead.
We did lift the egg up a little during that time to touch it and get a closer look at it. At first it was just a little soft. Over time the shell disappeared. It totally vanished. There was not any remnants of the shell left in the jar.
On day three we took at the egg and played with it on the kitchen table. It did indeed bounce. One of us decided that we should try bouncing it from eight inches off the table. That was too far! When the egg landed on the table it split open and the inside of the egg went everywhere.
It turns out the outer part of the shell that had become bouncy was very thin. The thin transparent shell area just couldn’t take pressure creating by a large drop.
We had a wonderful time discussing what had happened and when we could try this again. It was also decided that I should not be in charge of deciding how high to drop the egg down from. It turns out that I am not very good at that.

Fun! I can remember doing this as a kid.
I was wondering if it was was rubber inside too – lesson learned 😉
That’s interesting that the shell dissolves like that… I can see all kinds of fun coming from an experiment like this one. 🙂
That sounds and looks like fun!
Brad did this experiment not very long ago…it was weird how the shell just dissolved!
We had a lot of fun with this when we did it a couple years ago! Really we should probably do it again! Featured you on Mom’s Library this week!
This looks so fun; can’t wait to try it!
Definitely a fun science experiment for kids! Thanks so much for linking it up at After School.
It is appropriate time to make some plans for the
future and it is time to be happy. I have read this post
and if I could I desire to suggest you few interesting things or
suggestions. Maybe you could write next articles referring to this article.
I want to read even more things about it!
