THIS DISAPPEARING EGG SHELL ACTIVITY IS AN OLDIE, BUT A GOODIE!!
You probably did this egg experiment at some point growing up, maybe in school or as an at-home science experiment. The kids will love doing this!
DISAPPEARING EGG SHELL ACTIVITY MAKES FOR SOME KID SCIENCE FUN!!
What you need:
- an egg
- white vinegar (there are so many fun activities that use vinegar, so you may want to get this)
- a glass or jar
Start by gently placing the egg in a glass. (An ‘older’ egg does work better than a fresh egg.)
Cover the egg with vinegar leaving about an inch at the top of the glass.
Let it sit for about 4 days.
After several days, gently remove it from the vinegar and rinse it off in water. (I know this looks disgusting. ???????????? It’s just because I used a farm fresh egg, so that brown color is from that!)
You now have a shell-less egg!
What’s so cool about this is that you can watch the yolk move around when you move the egg. And the texture of the egg is like a bouncy ball. It’s so interesting!
We bounced ours around in the sink for awhile, and it was like a bouncy ball! The kiddos loved it. It’s fun with the kids to start by dropping it low, then get a little higher, then a little higher until eventually it breaks, and you’re left with just a white membrane in your hand.
Just be sure you bounce it in the sink or outside because IT WILL BREAK, and you really don’t want to deal with that mess to clean up, RIGHT?! ????
We’ve got some more cool things for kids to do!
I am so excited to do this experiment with my second grader! Totally forget about it! I’ll also be attempting the osmosis with corn syrup! Thank you
Apparently you can teach osmosis by putting it in corn syrup after you do the vinegar (obviously if it doesn’t get popped by then). The inside will seep out through the membrane then if you put it in water (can add color for fun) it will absorb the water back into the membrane. Apparently you can do this over and over again (corn syrup to water and back to the corn syrup.)
