Osmosis Egg Lab Before the experiment, the egg weighed 2.2 g and measured 15.2 cm in circumference. It had a white shell and looked like an ordinary egg. After making the required calculations, 300 mL of vinegar were poured into a beaker. The egg was dropped into the liquid, and hundreds of tiny bubbles formed on its shell as it sank. A plastic bag was placed on top of the beaker. After exactly 24 hours the egg changed noticeably. It increased in size and weighed 0.7 g more than it did before submersion. Its circumference also grew from 15.2 cm to 16.8 cm. The shell practically dissolved, and only a thin, transparent membrane was stopping the insides from completely spilling out. This made the egg very squishy and fragile. Next, the beaker
