Thirsty Celery
You need
- Celery stalks with leaves
- Clear cups of water
- Food coloring
Let's play
- Fill cups with water and add lots of food coloring.
- Put a celery stalk in each cup.
- Guess: what will happen to the leaves?
- Check the next day. The color climbs up the stem to the leaves!
Grown-up tip: Cut the stalk across afterward to see the little colored dots: they’re the "straws".
