Shot with a high-speed camera at various frame rates, the precisely controlled water droplets were launched at the nanotube arrays at different velocities and at different impact angles. The first segment of the video shows a simple 30 microliter droplet of water striking the array at two different speeds. At a slower 1.03 meters per second the droplet bounces off the nanotubes almost completely intact; at increased velocity it breaks into several smaller droplets and scatters in different directions.
