The pressure pushes in all directions save one,
downward (toward the nozzle).
All the forces are balanced except one: the push on the top of the bottle.
alkaselser and water
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
Water, an empty plastic bottle and an air pump.
If you are in Science Olympiad, a bottle rocket is a modified 2 liter bottle designed to stay up in the air longer than its competitors. Another type of bottle rocket is a type of firework you place in a bottle to make it launch.
Because the high air pressure inside the bottle is trying to go to the lower air pressure outside the bottle, after more air is pumped in until the pressure builds up too much, the bottle rocket will be force into the sky by the air inside it.
it pushes the rocket into the air to make it go higher.
You can make a soda bottle rocket.
alkaselser and water
You can make a stand, this will stable the rocket and allow it to stand up-right.

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
1Prepare two 1250 ml PET bottles2Cut one of the bottles into three parts. Please keep the bottles top and middle section.3Stick the bottles top into the other PET bottle's bottom part. 4Stick the first bottle's middle section into the second bottle's top part. (Please use the insulating tape.) 5Cut four acrylic boards as the four empennages of the rocket. 6Pour about 200 ml Water into the bottle. 7Cap the rocket into the inflater ready to launch. 8Put the rocket into the launch pad. 9Pump the air into the bottle. 10Make sure the atmospheric pressure in the bottle is about 70~75 percent. 11Launch!
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 some cardboard, make a cone, and tape it to the top of the bottle.
make it hold as much pressure as possible and experiment with the amount of fluid/air.
