Are you able to add volume to the bottle if you leave it intact and unmodified and only use one bottle and do not exceed the 2l limit?Pressure vessel and fuselage of rocket must be constructed from a single unmodified soft drink bottle which cannot exceed 2 liters (labeled capacity) volume. (commercially produced stretched or modified bottles such as the U14 stretched water rocket bottle by Anti Gravity Research are not allowed)..

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

Re: Class D rules question
No you may not alter or modify the bottle in any way. You can choose any shape bottle you wish or even use a bottle that is smaller than 2 liters. There are a lot of possibilities.
Good Luck.

Re: Class D rules question
By inclusion of the word 'primarily' am I allowed to try different additives to the tap water?3.Reaction Mass must be primarily ordinary tap water.

Re: Class D rules question
You can try different additives in the water but please be kind to the environment. An example would be to add salt to the water to prevent freezing or adding sugar to increase viscosity. Flammable additives are prohibited.
