A Pretty Purple Egg
This is the final in our series of egg experiments. We took our sad shrunken egg made it grow. We colored the water to show the water movement. Froggy chose purple which we made by mixing red and blue.
Then we placed our shrunken egg in the colored water and left it there for approximately 24 hours.
The water moves easily into the egg across the semi-permeable membrane bring the food coloring with it. This creates a pretty purple egg.
