Why does pasta foam?

Foaming pasta

You'll also notice that potatoes foam too. It's the starch in the pasta (or potatoes) that causes the foaming action. Why starch foams is another question altogether and that I don't know the answer to!

Tip:

If you add a little oil to the water it will stop foaming.
