What are fluids?

Fluids are things that can flow and change shape easily, just like water or air.

Fluids are like a group of friends who love to move around, they don’t stay still in one place. Think about honey pouring from a bottle: it moves slowly but still flows. That’s a fluid too!

If you have something that can squish or slide, it's probably a fluid. Like when you put your hand into a bowl of soup, the soup moves out of the way and goes back in, just like how water feels when you swim.

• Water is a fluid, it flows from the tap to your glass.
• Air is also a fluid, it moves around you when you run or blow out birthday candles.
• Even something thick like jam can be a fluid, though it takes longer to move than water.

You don’t need magic to understand fluids, just look at how things move and change shape every day!
