Water Rocket Safety

The use of pressurised gas of any kind to power SCA missile weapons is currently prohibited.

These pages detail a series of tests carried out by the Lemmings in order to demonstrate the safety of the water rocket cannon design


Impact Comparison

In this test the impact of the water rocket was compared with a throwing axe, javelin and arrow.

It was determined that the impact of the water rocket was comparable to the impact of thrown axes and javelins.

Impact Comparison 2

In this test the impact of a water rocket was compared with the impact of bolts fired from a ballista.

It was determined that the impact of the water rocket had less than one quarter the force of the ballista bolts.

Flight Testing / Modeling

The range of the water rocket and ballista was measured at a series of different angles.

A mathematical model of the flight was developed to assist in making a comparison between the two.

Operating Pressure validation

In these tests 100 PSI was validated as a safe operating pressure for water rockets constructed from 600 ml PET coke bottles.

Risk Assessment

In these tests the conditions under which a water rocket might explode are examined. An assessment is made of the risk involved in such an explosion.
