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.
How to make a water rocket and parachute
Create one bottle rocket that will fly straight and remain aloft for a maximum amount of time.
Two 1.5-liter bottles
One small plastic cone (athletic)
Large Plastic Trash Bag
Masking Tape or Avery Paper reinforcement labels (you'll need 32/chute.)
o Cut the top and the bottom off of one bottle, so that the center portion or a cylinder remains.
[pic] o Tape the cylinder to another bottle to create a fuselage (a place to store the parachute).
o Get the manila folder; fins will be made from it. Cut three shapes out of the folded bottom in the shape that the diagram shows. Your fins will be triangular.
o The next drawing indicates how the fin should look once folded.
o Mark straight lines on the bottle by putting the bottle in the door frame or a right angle and trace a line on the bottle with a marker. Use these lines as guides to place the fins on the bottles.
o Make three fins and tape them on the rocket. Be sure that the fins are spaced equally around the
