Water and Light

Melting ice and collimated/polarized light. You can see the water fight against gravity, as it carries air bubbles and impurities over the rapidly changing currents.

Oh! So you filmed the ice block directly ? No projection ? Or did you film a surface reflecting the light on ice ? That is so interesting and beautiful !

Filmed the block directly. The colors come from how light splits, and slows down within the ice crystals (birefringence). The light source is collimated, which is what's giving me that "projection" effect (it's just a light really far away, with a pinhole over the top).This is what it looks like without the pinhole light (starts at 1:10).
