Australian science teachers amuse students with giant cola-powered rocket launch

Two science teachers launch a DIY rocket into the sky using five bottles of diet coke mixed with liquid nitrogen to amuse their onlooking students at a school in Gosford, Australia.

The pressure of liquid-turned-gas nitrogen forces the soda out the bottom, launching it into the air during the National science week inspired project on August 13.

Jacob, one of the science teachers, comments on the success of the project saying: "You can hear the excited voices of the Primary age children in the background. Some senior students dressed up as astronauts are playing in the foreground."
