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.
