Planetary scientist Sheila Kanani visits The Hollyfield School in Surbiton to deliver a workshop on comets, as part of a programme to encourage students to enter STEM careers.
Using a variety of common household ingredients and some dry ice, she demonstrates how it's possible to cook up a comet in the classroom. She also explains to students how they can follow in her footsteps and pursue a career in space science.
Sheila talks about her work on the Cassini spacecraft, currently orbiting Saturn, and gives us an insight into what it's like to work at the cutting edge science.
