Weights – Water Rocket Parts

This page shows the individual parts of a water rocket and their corresponding weights. I will add to and update this page over time. This page is available in the Weights Category section under Archives above.

The digital scale I have weighs in increments of 1g up to a maximum of 3000g. I will put the ounces equivalent beside the grams weight in the table.

This information may be useful when determining the weight of your water rocket while using simulators ie: Cliffords Wrocket Simulator
