How Many Drops to Fill the Dot?

Draw some different sized circles randomly around a piece of paper and laminate it.

Next, prepare a few cups of colored water with water and food coloring.

Then start counting how many drops of water it takes took to fill the dots.

Since they are different sizes, it can be interesting to compare.

Then can you of course add thoughts around surface tension if you want to expand the experiment.
