### In the lessons

In science, test tubes hold small amounts of liquids in experiments, and the body has tubes like the windpipe (trachea) and food pipe; plants have tiny tubes that carry water. In everyday life we squeeze toothpaste from a tube and travel on the Tube in London. In art, paint comes in tubes. Phrases: "test tube", "a tube of toothpaste", "inner tube" (inside a bike tyre), "take the Tube", "cardboard tube".
