This is an experiment in osmosis.
We think it is pretty cool!
You start with raw eggs, vinegar and clear jars.
Use as many eggs and jars as you want.
Fill the jars with vinegar and carefully put the eggs in the jars.
Wait 24 hours......
Then, empty the vinegar (carefully) and pour in more vinegar.
Wait another 24 hours...
Your eggs should look like this. The vinegar has dissolved the egg shell.
You can carefully rub off any remaining shell with your fingers.
Then, we put corn syrup in the 1st jar, tap water in the 2nd jar, red food coloring with water in the 3rd jar, blue food coloring with water in the 4th jar, green food coloring with water in the 5th jar and tap water in the 6th jar.
Wait another 24 hours....
The shriveled egg was in the corn syrup. Water is sucked out of the egg by osmosis. The corn syrup has less water in it than the egg, so it balances itself out.
The 2nd egg was in water. There is more water outside the egg than inside, so the egg sucks the water into it.
The 3rd egg was in vinegar, so it should have stayed the same as it already was.
This is the egg from the corn syrup. It looks kinda gross! And the yolk is very firm.
These other eggs are gushy and squishy. Kinda rubbery and fun to play with.
But be careful not to pop them! What a mess you would have then!
The next 3 eggs are really cool! They look like really bright Easter eggs.
The water isn't nearly as colored now, because the color was sucked into the eggs along with the water.
Nathan is looking at the red egg...
After we popped the red egg, we felt the membrane. It looks and feels like a popped balloon.
We dropped all of the eggs in the sink at various heights to see how high we could get them before they popped. This is a messy part, that's why we did it in the sink. We had 6 eggs because we originally intended to pop just the 6th egg, but then decided we might as well pop them all! More mess, more fun!
Because these eggs have been out of the refrigerator for so long, and because they were soaked in water, vinegar, corn syrup and/or food coloring, we strongly suggest that you do NOT eat any of the eggs from the experiment!
