World First RPG Propelled By Water Bottle Rocket
This is the RPG that I have created that is propelled by pressurized water and air. If you can’t see me, I’m at the far right of the video, the spot where I launched the RPG water rocket.
For this video, the rocket is pressurized to 60psi and filled with 250ml of water. You can see that when the rocket is launched, there is some short burst of water spray which is the reaction mass that help to propel the water rocket forward.
This happens because water is forced out of the rocket by the pressurized air.
The water rocket then reaches a peak when the water has all expelled out, it then descends back to the ground due to the force of gravity.
RPG Powered By Water Rocket
I saw this youtube video on how someone actually creates a “missile” using water rocket and shows his creation to a group of students.
In the video, the man is speaking cantonese and i believe he’s from Hong Kong.
He explains that the entire water rocket is made from mostly recycled materials like your coke bottles but you need to spend some time to make it work.
What I’m amazed is that he can control the “missile” with accuracy and i think it’s very educational and fun for students to learn from this experience rather than playing their video games.
For more details, you can click here to go to his website. It’s a chinese
site so you might need some translation.
How To Make A Water Rocket – Step By Step guide
Make a Soda Bottle Rocket – More amazing video clips are a click away
A step by step guide to make a soda bottle rocket. With a few empty soda bottles and some PVC pipe, you can build a high-performance water rocket.
This is a more difficult way to build the water rocket because it uses the “open neck nozzle” method, where you will need to use the pvc pipes to build a launcher that will launch the water rocket.
You will need to cut,file and drill holes on the pvc pipes and this poses a problem for those who do not have the tools in their home.
The o-ring may cause some problems when launching the water rocket, so you need to ensure it is not too tight. Also, you will have to make sure that that is enough support for the launcher so that the water rocket can be supported and launched vertically into the sky.

What Is A Water Rocket?
As you can see from the video, a water rocket is simply a cola bottle pressurized with water and air.
It’s also commonly called the “water bottle rocket” because any carbonated bottle can be used as the body of the water rocket.
The rocket in the video is an inverted 2 litres coke bottle filled with 500ml of tap water and attached to a bicycle pump.
The coke bottle have fins attached to make it balanced so that
it can fly upwards into the sky.
The coke bottle is attached to a bicycle pump creating an air tight
connection. As the boys starts to pump air into the bottle, air cannot escape and thus pressurized inside the bottle.
This creates a great source of potential energy which when released, will propel the bottle high up into the sky.
