The Science of Meringue:
Just using water will not make the eggs into a foam. Egg whites are already 90% water and 10% protein. These proteins curl and fold together from being large chains of amino acids. Some of the amino acids will bond with water and some will repel water. The molecules while whipped bounce around. Add you whip the eggs it creates air pocket forming bubbles. These bubble make the foam.
