Science Buskers Water Rocket Car
As i will be participating in the Science Buskers busking round from 10 to 12 September 2010, I have thought for quite a while before deciding to build my own water rocket car from Lego to demonstrate the power of water rocket.

It took me about 2 hours to build a full model of a dragster like Lego car and then a number of days to modify it to become the water rocket dragster car.

I did some initial testing pump in 80psi of air into the 500ml bottle, and the car ran really fast. I then add some water and pressurized to 40psi, it had a really fast acceleration. But when i tried 60psi with the same amount of water, the car flipped instantly when it was released.

I guess i need to modify the car further to make it more stable so that it can take more water and pressure. As suggested by some experts, I adjust the length of the wheel axle to be broader for the front and rear wheel and added a pair of fins to provide the downforce; finally, managed to get the water rocket Lego car speed off at 60psi …..
Water Rocket Car – Drag Racing
This is one of the most amazing water rocket car I have seen. I believe this is probably one of the fastest car on earth using just water and air. The car is believed to be built by the Japanese in 1996 and it seems they are already so advance at that time.
The cars look so professionally developed and it’s cool. A pity I can’t locate the original website but I hope I can built this type of water rocket car one day.
Science Buskers 2010 – Water Rocket Through To Busking Round
After the Science Buskers 2010 audition on 5th August at Singapore Science Centre, Water Rocket was shortlisted and will be performing in the busking round from 10-12 September at Plaza Singapura.
Science Buskers Festival 2010
We want to thank the judges for choosing Water Rocket to be in the busking round and will be thinking of ways to entertain shoppers over there. We will probably be showing how a toy car can be propelled by water rocket, using just water and air.
If you want to send some package over to your friends at the opposite block but lazy to walk all the way to his house, what do you do? How about using Water Rocket to transport them over to your friend’s place in a matter of seconds using just water and air?
I will be showing how these ideas can put to practically use at the busking round, so if you want to see how all these can be done, do come and visit our Water Rocket booth to have some hands on experience.
Water Rocket RPG Launched At 100psi 500ml
This is another one of my water rocket RPG launch at Seng Kang open field. The rocket was filled with 500ml of water, which is the maximum, anything more than that will slow down the rocket.
The rocket is then filled with air through a quality bicycle pump to an air pressure of 100psi, which is more than 3 times the normal air pressure of a car tire at around 30 psi.
For this test, the rocket fly way too high up to the sky probably because the angle of launch was too much, around 70 degrees. Ideally, it should be about 45-60 degrees to obtain a long horizontal distance.
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.
