The first stage of the experiment was to soak the egg in vinegar. You will have seen that the shell completely disappears. Vinegar in fact contains acetic acid and this reacts with the calcium carbonate making up the shell of the egg. This reaction gives off carbon dioxide so if you were paying attention you will have seen bubbles coming off the egg as soon as it was added to the vinegar.

The membrane around the egg also becomes very rubbery during this soaking in vinegar. This occurs because the acid denatures the protein making up the egg white (albumin). Denaturation of proteins can occur through exposure to acids, bases or high temperature. This is what happens when you cook an egg- the clear egg white turns opaque and white as the protein chains become tangled due to the heat.

If you soak a cooked egg in vinegar it also becomes very rubbery- so much so that it will bounce when dropped from a low height! Its not a good idea to try this will an uncooked egg as inside the rubbery membrane the yolk and white are still runny and it will make a big mess if split!
