We tried some science experiments these past weeks that the kids loved. We made rainbows with paper towels and celery!
Paper Towel Rainbows
First we got down seven glasses, four of which we fill half-full with water. We added food coloring to those half-filled glasses, two with red, one yellow, and the other blue.
Then folded up paper towels and placed them in both the colored glass and the empty one next to it.
This experiment takes a long time (about 24 hours), so you’ll need to find another activity as the water gradually gets absorbed up the paper towel.
The next day, we started to see the colors start to mix as they came out of one glass and went into the other.
One beautifully colored rainbow!
We also decided to experiment with celery. So we placed a stalk in a fresh cup and added food coloring.
The one at the end was a surprise color. I believe it came out dark greenish red.
The kids got to see not only the rainbow, but how water flows through a plant, like celery,
through the veins
and into the leaves.
