You could do an osmosis experient. What liquid can penetrate through an eggs shell the most? The manipulated variable would be the different liquids. Just put three raw eggs in three different liquids ex: (water, vinegar, milk) After a few hours take the eggs out and weigh them. Depending on the liquid, whatever egg weighed the most had the most permeable membrane. That liquid could pass through easily. It's an easy experiment. I've done it.
