High Speed Video !
Everyone has seen rain drops falling on the surface of a puddle or lake, or has watched drops of water fall from a leaky faucet into a glass one by one. However, most of us probably haven't seen how a drop of water changes shape during a splash. When we are able to see more detail in a drop or splash, we can ask questions about what we see. High-speed photography allows us to appreciate these events.
Here's some high speed video clips taken by high speed video camera.
