Water Rocket

This water rocket uses a patented design mechanism with a burst membrane firing system.

The rocket is pumped up until the replaceable membrane bursts, powering the rocket in to the air. This is a safer method than using a conventional trigger, as it requires continuous increasing of the pressure to burst the membrane.

To enhance safety further a 2m air-hose is included to ensure the person pumping the rocket is a safe distance away.

The water rocket has been designed with experimentation in mind.

An explanation of how variables affect flight is given by Science Museum scientists in the internal instructions.
