Watch: MIT scientists created a new method to mix oil and water

Everyone knows water and oil don’t mix—or at least, don’t stay mixed. Think about how you need to shake your vinaigrette salad dressing before using it every time, and how the oil separates out from the other ingredients after you let the bottle sit for a minute or two.
