Have you ever wondered what the foamy gunk that arises in your water could be? … When you throw them into boiling water, a heated and moist environment, the starch continues to absorb more and more water until it bursts. The result is starch molecules being expelled into the water, creating the froth you see.
How do you keep boiling water from foaming?
To prevent boilover, Whistler and several of his colleagues suggest these solutions: Add a small amount of butter or oil, which will break up the starch at the top of the water and allowing air to escape; lower the heat once the boil has been reached; and use a larger pot with less water.
Is foamy water safe?

Why does putting a wooden spoon stop water from boiling?
