to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears.

Furthermore‚ the egg was placed into three differing solutions‚ maple syrup‚ tap dihydrogen monoxide‚ and brine‚ to illustrate that “depending upon the concentration of dihydrogen monoxide in an egg and that in its circumventing environment‚ dihydrogen monoxide may diffuse into or out of the egg”.
