Great talk, thank you! David Hu talking about how animals repel water: 1. ant rafts, water-repellent surfaces, surface tension 2. mosquitos vs water drops, 3. mammals shaking off water. Covers a lot of fascinating ground. (It's not a great quality video but he shows a lot of videos too which are mostly visible enough.) David seems to have qualifications in biology, mathematics and engineering!
