Due to its dark body, the solar airship (3 x 1 meters) absorbs the majority of the rays of the sun that fall on it. The air in the airship becomes lighter (less dense) as it warms up.

With one single drop you can do an incredible amount of experiments and surprise others with them as well. It only takes one drop to create a magnifying effect, a vortex ring or the lotus effect. A drop can sink, splash, bounce, or even float. But you have to be very gentle to make sure that only one drop will trickle from the pipette!
