Horrible Heavens: The Petrifying Planets

Institute of Astronomy Public Observing Evening and Public Open Day, and Cambridge Science Festival Special Event (2011-13)

With Jonathan Crass

We explore the physical conditions (the temperatures, pressures, etc.) at different places in the solar system, from the surface of the Sun all the way out to Neptune and Pluto with a number of demonstrations including dry ice, liquid nitrogen and exploding hydrogen gas!
