BRING SCIENCE HOME Separation by Distillation Can you separate the ingredients of a solution using just heat? Try this sweet activity and find out!  Credit: George Retseck Do you like cooking? If you have helped in the kitchen at home or watched someone else cook, you have probably seen lots of liquids—such as water, milk and soup—heated. Did you notice that once the liquid boils, a lot of steam develops? Have you ever wondered what the steam is made of and what happens to all the substances such as sugar or salt that are dissolved in the solution you are boiling? Do they boil off, too, or do they stay behind in the solution? In this activity you will build a distillation device that allows you to sample the steam that you generate while boiling a fruit juice! How do you think it will taste?
