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.

∙ 11y agoNormally small fireworks like bottle rockets use black powder as a solid propellant. Black powder has a lot of chemical energy stored inside of its molecular bonds. When you apply a spark or flame to black powder, the black powder combines with the O2 in the air and a lot of heat energy is released. When a gas goes from room temperature to very hot very quickly, it suddenly takes up much more space. If you have two gases that are exactly the same, the one that's hotter will have more volume (it takes up more space). Inside the bottle rocket, as the gas expands it pushes out in all directions, normally in a rocket engine like a bottle rocket it only has one direction to come out, the bottom. When it shoots out the bottom the gas is moving very quickly, and even though the gas doesn't weight much, it's being pushed away so fast that the rocket (which is much heavier) get's pushed in the opposite direction, forward.
Just to sum it up, heat starts a chemical reaction, chemical reaction makes more heat, gas expands, pushes out the bottom and pushes the rocket up, up and away.

What is Bottle rocket?
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.
How do you think your bottle rocket will fly?
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)
What things do you need to make a water rocket?
Water, an empty plastic bottle and an air pump.
Why when you suck a air of a bottle it shrinks?
When you suck air from a bottle you create a partial vacuum and there is less air pressure in the bottle; but outside there is atmospheric pressure so it tends to collapse the bottle.
Why it is easy to remove air from balloon than from bottle?
This is because the air inside the balloon is a fairly high pressure than the atmospheric pressure air outside the balloon. On the other hand air pressure inside the glass bottle is already equal to the atmospheric pressure so it is difficult to remove air from a glass bottle.
What effect does pressure have on a bottle rocket?
it pushes the rocket into the air to make it go higher.
Air and water pressure for a 1.5L bottle rocket?
1:2

How do bottle rockets fly?
The 'operator' fills the bottle with water, then pumps air into it - creating pressure. When the stopper is released, the air pressure forces the water out of the narrow opening in the bottle's neck - creating a stream powerful enough to launch the rocket into the air.
What is the best way to design a bottle rocket that will travel the highest altitude?
make it hold as much pressure as possible and experiment with the amount of fluid/air.
How do you make the bottle rocket stay in the air as long as possible?
add more mentos!
How does air pressure effect the height of a bottle rocket?
THe ideal amount is 50% air pressure and 50% water. SHoot from 4-6 bar. I got mine to 92 meters

Why do bottled rockets fly?
because of the different amounts in pressure, the bubbles in the bottle are making more air and more pressure inside the bottle and when the cap comes off or however you do it. the air inside the rocket rushes out to try to equilize the pressure, causeing it to also be pushed off the ground.
What made the air move in a rocket balloons?
the pressure in side the balloon will get squizz out and make the air move
