Using a straw to pull liquid up?





Hi P3 Faith pupils, do the simple experiment and answer the following questions:

1. When you drink liquid from a cup using a straw, are you really pulling the liquid up?
2. Explain why the liquid can travel up the straw and reach your mouth?(hint: related to air and pressure)
