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. <br /><br />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. <br /><br />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."
