What propels a bottle rocket firework?
Water rocket, a model rocket propelled by water and compressed air, sometimes referred to as a “bottle rocket” as they are often constructed from soda bottles.
How does a firework fountain work?
It has a solid clay plug at the base and a nozzle or choke at the exhaust end. At effect time the composition burns and the choke generates intense pressure inside the tube. As the composition escapes it sprays sparks, flame and gasses high into the air.
Why do bottle rockets fly?
Typically, a water rocket uses a plastic bottle in which the pressurized air, and water, goes in. When the air pressure becomes high enough, the plastic bottle releases and flies high up into the air. The higher the air pressure, the faster the water shoots out, and the greater the “push” force on the rocket.
What are bottle rockets fireworks made of?
Nozzles for fireworks rockets are usually made with clay. Bentonite and kaolin clay work well. The dry clay powder is rammed into the casing, producing a solid plug. Cheap kitty litter is often made of bentonite clay and may be used instead.
How long do firework fountains last?
Most individual fountains last up to a minute however with some lasting for 2-3 minutes.
What is the science behind bottle rockets?
When the bottle is released from the launcher, air escapes the bottle. As the bottle pushes out the air, the air pushes the bottle upwards (Newton’s Third Law of Motion). Increasing the thrust (adding more pressure to the bottle) increases the acceleration.
Can bottle rockets fly without water?
Why does it still work with no water? Even with no weight of water inside the bottle, the bottle rocket will still fly upwards.

How high do fountain fireworks go?
Ground-based fountains will shoot showers of sparks 5 – 9 feet in the air on average. Some of the larger fountains can reach heights of 12 feet. Rockets shoot 50 – 300 feet in the air depending on the size, quality and atmospheric conditions.
