How To Make A PET Rocket In Singapore
I was browsing online and found there is a video teaching you briefly how to make a PET rocket in Singapore. In this video, it summaries the steps and materials you need for building a PET bottle rocket or commonly known as water rocket in other countries.
Materials needed to build a water rocket:
1. Scissors
2. Duct Tape
3. Black Marker
4. 4 Fins from a PET bottle
5. A Gardena Nozzle
6. Nose Cone
Before starting, you will need to mark out some lines on the PET bottle so you can cut and make the fins. You have to ensure that the fins are equal in size and properly attached so as to ensure a stable flight.
Science Buskers Water Rocket Busking Round Day 2
Today is the day 2 of the science buskers busking round and for my water rocket show, I have got my wife and my brother-in-law down to help me out.
I also want to thank some of the brothers and sisters from my church including Wee Chung & Serene, Chee Wan & Yoke Leng, Cheng Sheq and Soon Ting, Gay Teck and Shao han and of course my best friend Bernard & Qiuyun ….. just want to say thank you for all your support.
One of the reasons why I joined the Science buskers is to show to people, especially children and teens that water rocket is such a fun activity to do and you can get your entire family in to launch water rockets providing hours of fun….
It really warms my heart to see the following participants who tried out my water rocket and vote for my booth… i believe that they really enjoyed themselves and that makes my day… Thank you….
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.
