Select the liquid.

[ "beads", "lemonade", "air inside a balloon", "empty cup" ]

B

An empty cup is a solid. A solid has a size and shape of its own. When you fill a cup with water, the cup still has its own shape. Each bead in the jar is a solid. If you put many beads into a bottle, they will take the shape of the bottle, as a liquid would. But be careful! Beads are not a liquid. Each bead still has a size and shape of its own. The air inside a balloon is a gas. A gas expands to fill a space. The air inside a balloon expands to fill all the space in the balloon. If the balloon pops, the air will expand to fill a much larger space. Lemonade is a liquid. A liquid takes the shape of any container it is in. If you pour lemonade into a cup, the lemonade will take the shape of the cup. But the lemonade will still take up the same amount of space.
