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."

It's National Science Week in Australia and the theme is 'Destination Moon'.
These two Science Teachers make and launch a giant rocket.
Inside the rocket is a large 15 litre office water bottle.
The Teachers first pour 5 bottles of diet coca cola into the upside down rocket.
About 1 litre of liquid nitrogen is then quickly poured in.
The rocket is then turned over. The liquid nitrogen rapidly turns to a gas and forces the diet coke out the bottom of the rocket. As the rocket pushes down on the coke, the coke pushes up on the rocket causing the rocket to soar into the air.
