2:38 i wonder if the pigment in the jelly would react to UV?
4:30 I have an idea. what if, you had string attached to the outed rim of the lens on the left/right/top and just kept them out of view of the camera recording. it should give you a rough area to be when dropping and hitting the object/jelly
During 7:09 the background lighting those little droplets of jelly is making would make for an amazing animated wallpaper. Does anyone know of something like this? Or if that kind of flashy lighting has a name?
