What can a humble airplane sick bag teach us about physics, engineering, and the limits of the human stomach; And why are there people out there collecting thousands of them? Professor Hannah Fry and VSauce’s Michael Stevens turn an unlikely holiday prompt into a surprisingly rich exploration of flight. From the biology of motion sickness to the physics of turbulence, and from exploding crisp packets to next-generation aircraft design, they unpack how flying messes with your body and how science has made it (mostly) better. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
