Water rocket competition

24 of February. I joined water rocket competition in our University which organized by engineering society. This first time involved in water rocket competition.

Here my group members and our rocket.

It's fun when experienced the process modifying our rocket.Wonderful feeling at the last trial. Which four rocket successfully launched from platform and we get 4st of 8st group.

It look like bomb!!!

About water rocket on wikipedia

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel—the engine of the rocket—is usually a used plastic soft drink bottle. The water is forced out by a pressurized gas, typically compressed air.

The term "aquajet" has been used in parts of Europe in place of the more common "water rocket" and in some places they are also referred to as "bottle rockets" (which can be confusing as this term traditionally refers to a firework in other places).

Water rocket engines are most commonly used to drive model rockets, but have also been used in model boats, cars, and rocket-assisted gliders. Water rockets are also popular in school science experiments
