If you mean the water-and-compressed-air powered toy rockets, they generally work best when filled about halfway... but don't take my word for it, try different water levels and see!
the right amount of water to put in a bottle rocket so it will fly high is 70 milliliters
alkaselser and water
2l of water plus some ground up orange rinds to boost the takeoff
inside the rocket
1/3 gallon or 1/2 a galoonyou need to add 1/4 water to the water rocket. you put a vitamin C into the water and vitamin c will dissolve and fly into the air.

take 2 l. bottle cut the bottom of a bottle off put the 2 bottles together take a piece of balsa wood and make the wings fill the bottom part of the water rocket with paper put the wings on the bottle rocket cut a circular cup in half put a tennis ball on the cup
get a 2 litre bottle put a cone on top get a lancher then pump it up and BLAST OFF!!!!!
inside the rocket
A 2-liter bottle will be required, as a 20-ounce is too small. Remove the label and take the cap off, but save this cap. take a pen apart and saw the barrel of the pen in half. Outline the size of the barrel on the top of the cap. Drill a hole this size into the cap. Using cardboard paper, construct 3 or 4 fins for the ship. A foam football cut in half can make the nosecone of the rocket, but a piece of paper can substitute. Once the nosecone and fins are attached, put the pen barrel in the bottlecap, and attach a bike-pump to the pen barrel. Fill the rocket with water, put the cap on, and pump air into the rocket until it blasts off.
you put some water in the bottom of your rocket/bottle and get a bicycle pump keep pumping air in to the rocket sets off and make sure you watch your face they can be highly dangerous! hope this helps

because if you don't, the bottle could tip over and fly into a house or it could hit you or other people. If you don't know that, you shouldn't be playing with fireworks...
Take a 2.5l bottle of pepsi and then add 10 mentos peaces.... and then close the cap and put it upside down.............
put a cherry bomb in it and time it.
