What is the world record for a water rocket?

2723 feet
World records The current record for greatest altitude achieved by a water and air propelled rocket is 2723 feet (830 meters), held by the University of Cape Town, achieved on 26 August 2015, exceeding the previous 2007 record of 2044 feet (623 meters) held by US Water Rockets.

How do you make a water rocket go higher?


  1. Use higher pressures.
  2. Keep weight to a minimum.
  3. Increase rocket volume.
  4. Streamline the body of the rocket to reduce drag.
  5. Use a launch tube on the launcher.
  6. Use the right amount of water.
  7. Use an optimum sized nozzle.
  8. Use multiple stages.

How high can a water rocket go?

Water rockets are easily capable of 100 m high flights, but advanced hobbyists have combined bottles and staged bottles for flights over 300 meters high. Water bottle rockets are ideal for teaching Newton’s laws of motion.

Is more water better for a bottle rocket?

The mass fraction of the rocket (mass of propellant/ total mass) will be close to 1, and the rocket will be very efficient. The more water you add, the more propellant you will have, and the higher the rocket will fly.

How do you use a ginormous rocket?

The Ginormous Rocket is SEVEN FEET TALL and launches over 150 feet into the air! Fill the water bottle and then pump to pressurize the hose. Simply squeeze the launch bulb and let that rocket fly! From all over the neighbourhood, people will look up and see your Ginormous Rocket shooting toward the clouds!

How many fins should a water rocket have?

3 fins
You can use no less than 3 fins on your rocket. Attach the fins to the lower section of the rocket using glue, Velcro, tape, or other adhesives. Tip: It is easier to attach fins to a bottle that is slightly pressurized. You can pressurize the bottle by placing the bottle with its top off in a freezer for 2-3 hours.

What is the best nose cone shape for a water rocket?

rounded curve
Nose cone and rocket diameter affect drag If the speed of a rocket is less than the speed of sound (1,200 km/h in air at sea level), the best shape of a nose cone is a rounded curve.

Will a bottle rocket 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.

What is the best rocket fin shape?

elliptical fin shape
Theoretically, the best fin shape for a rocket is an “elliptical fin shape.”

What is the best fin shape for a water rocket?

What is the most aerodynamic nose cone shape?

Nose cone and rocket diameter affect drag If the speed of a rocket is less than the speed of sound (1,200 km/h in air at sea level), the best shape of a nose cone is a rounded curve. At supersonic speeds (faster than the speed of sound), the best shape is a narrower and sharper point.

What is the world record for launching a water rocket?

The Guinness World Record of launching most water rockets is held by Kung Yik She Secondary School when on 7 December 2013, they launched 1056 of them at the same time.

What is the world record for open design unreinforced Bottle Rockets?

The rocket that holds the flight duration world record. The class D record rocket ready to launch! Be the first team to fly an Open Design Unreinforced Bottle to a world record altitude. There currently is no official record for Open Design Unreinforced Bottle water rockets.

What is a water rocket?

Water rockets are typically constructed using soft drink bottles and powered by compressed air and water. Since our founding in 2003, we’ve become the largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

Are there any people who build water rockets?

There’s a fairly robust community that builds and launches water rockets. You know, regular rockets in pretty much every way except for the fact that they use pressurized water and air to launch into the sky.
