Thank you, Danger!
I am writing preschool science books that help children learn the science behind the activity, as you mentioned. It will also encourage them to think and guess (predict) instead of just being "handed" the answers. I believe this develops a measure of common sense...
Thank you Marcus! This is exactly the information I needed.
Here are two more activities that I would like to verify:
What happens, scientifically, when you float two toothpicks in water then dip a straw with dish soap into the water? Or similarly with pepper in water and dish soap?
