A few days ago, Aya herself reminded me that we haven’t done any experiments in a while. Uh-oh. I had been too wrapped up with so many things that I forgot to devote some time for this. I said OK. Right away Aya took out the book and chose which experiment we’d perform! I obliged, even if it was a weekday. As much as possible I wanted to do the experiments on weekends, where we have more time to spend. Anyways.
This experiment is relatively easy to do. Things you will need: Plate, milk, food coloring, and washing-up liquid. This experiment illustrates a literally colorful way to explain surface tension of liquids.
