Why does cotton candy disintegrate in air? What happens when you add droplets to candy floss? And how is it made in the first place? Discover the physics of cotton candy and the fluid dynamics governing its behaviour. Research by Stéphane Dorbolo at the University of Liége. Interview with University of Oxford Mathematician Dr Tom Crawford. Tom is an Early-Career Teaching and Outreach Fellow in Mathematics at St Edmund Hall: https://www.seh.ox.ac.uk/people/tom-crawford This video is part of a collaboration with the Journal of Fluid Mechanics and the UK Fluids Network featuring a series of interviews with researchers from the APS DFD 2019 conference. Sponsored by the Journal of Fluid Mechanics and the UK Fluids Network. Produced by Tom Crawford.
