Just a drop of experiment from Kraul

What - just a drop? A single drop should be enough?

With a single drop you can do a surprising amount of experimentation and surprise others with your experiments.

With just one drop you can create a magnifying glass, a swirl ring or the lotus effect. Just a drop can sink, splash, bounce or even float. But you have to be very careful so that only a single drop drips out of the pipette at a time!
