I would have named it “Water Droplet Bouncing on a Superhydrophobic Carbon Nanotube Array ” but I wasn’t sure if you’d look if I did.
From the YouTube description:
“All parts of the video were captured by high speed camera operated at
various frame rates. The droplet was illuminated from behind with a diffuse
halogen light. The droplet was dropped on the surface by at-tipped needle
and the volume of the droplet was controlled precisely by syringe pump.”
From me: “It’s really neat…watch it. (Oh and the sequence starting around 2:21…it’s like watching magic.) ”
