In order to better understand the procedure of osmosis better, I performed an experiment.
It required two unfertilized chicken eggs, vinegar, distilled water, and salt.
First, I soaked the eggs in vinegar for about 72 hours, which removed the shell, leaving the sac of yolk and whites.
Next, I poured distilled water in egg 1, and salt water in egg 2.
After a few hours, this was my result:
On the left is the distilled water egg, on the right is the salt water egg.
There is an obvious illustration of osmosis in these eggs, as it shows that molecules have passed through semi-permeable membranes.
