I got distracted from my usual wildlife watching today by some exceptionally loud bangs and explosions. It was all in the name of science outreach.|<\/p>\n

One of the campus roads was closed off while Professor Hal Sosabowski <\/a>and colleagues demonstrated the science of gas expansion with bottles of super-cooled carbon dioxide and liquid nitrogen. Basically (and I am no scientist) the supper cool gases are crammed into a tight space and expand as they heat up causing a massively loud explosion. The carbon dioxide (sequence hear expands to 50 atmosphere’s of pressure. The bottle can contain a mere 5 atmospheres. Hence… yes, you can work it out.<\/p>\n
