Depending on what you call a bottle rocket, you can go 2 ways
with this
The 2-liter soda bottle with water inside, and a rubber
stopper in the bottom is an effective rocket. It uses the
downward propulsion of the water to create forward motion, as
a rocket does. These can be easily made by obtaining a 2-litre
soda bottle, a rubber stopper to fit this bottle, preferably
with a hole in the centre, however one can be made to fit the
attachment of a bicycle pump. then just use a simple ringstand
as a launchpad and pump the bottle filled with water until it
is propelled upward.
If you are talking about the pyrotechnic bottle rocket,
flashpowder must first be prepared. A mixture of potassium
perchlorate and aluminium powder must be used. Build a paper
tube and wrap it in tape. Fill the tube with the powder
mixture and insert a length of cannon fuse into the bottom.
This fuse can be purchased at a firworks supply store.
I hope you found this useful
