Diffusion between hypo/hypertonic substances across a semipermeable membrane.
AKA: The water from the vinegar fills the egg
osmosis, where the vinegar solution moved from an area of higher concentration (outside the egg) to an area of lower concentration (inside the egg). This caused the egg to absorb the vinegar and swell, demonstrating the process of osmosis.
The shell breaks apart and the egg will expand and grow bigger!
It is an egg that has been boiled in water for a couple of hours.

An egg swells in vinegar because of diffusion. The vinegar has seeped through the egg's membrane, which causes the egg to inflate. However, the main reason you put the egg in the vinegar is because you want to dissolve the shell. This makes diffusion easier to occur on the egg's semi-permeable membrane. When you put the egg in the vinegar for the first time, an expansion is likely due to the carbon dioxide in the shells (it's the bubbles you see). This will expand the shell as the carbon dioxide attempts to escape.
A cracked egg, when mixed with the substance (vinegar), will cause nothing at first but will slowly desolve the egg shells and create the egg into a funny looking color. (If you want to try this at home, PLEASE WEAR GOGGLES!)
The conclusion for many concerning the bouncy egg experiment is that vinegar does cause the egg to bounce. After soaking a raw egg in its shell in vinegar for a few days, the shell dissolves leaving just the rubbery membrane that can be bounced.
Place the egg in a bottle filled with water and attach a parachute.
When an egg is placed in vinegar, the shell dissolves due to the vinegar's acidity. This causes the egg to increase in size as the vinegar penetrates the egg's membrane, causing it to swell.
The vinegar makes the egg soft because, the vinegar has a chemical reaction due to the Carbon Dioxide in the vinegar which has an effect on the egg. That's why the egg's shell dissolves off, and the egg gets soft.Correction:A raw egg will NOT bounce when dropped into vinegar. The egg must sit in vinegar for about 24 hours, so that the vinegar will react with the carbon dioxide in the egg shell, before the egg will become soft and rubbery. See link below.
