What is a Pop Bottle Rocket?
A pop bottle rocket uses a 2L pop bottle, which then, you fill up the 2L pop bottle with water, and then with air, air pressure is created, and when you launch it Newton’s law happens. A lot of people put designs on their rockets, such as mine I did not leave it plain, I added cardboard, fins, color, nose etc. To make the rocket fly high and far away, you have to understand on how to make your rocket aerodynamic. Below this is an example on how a water rocket can be launched.
Observations from prototypes:
(Prototype rockets are much smaller and use 500ml pop bottles)
I tried to make my prototype rocket have a pointy nose, just because it can be aerodynamic, pointy nose rockets fly great, it’s just after the rocket has crashed nose down, it will fail to protect the egg because the landing will be harsh and we are supposed to protect the egg on the actual rocket. After, I put 1 or 2 small rocks into the nose cone before gluing it on because then it will have a high center of mass which will make it actually fly like a rocket. I never flew my rocket because I was away on the day we did, and I did not make any fins as I was away for the previous days as well.
Here is my prototype rocket;
The Construction Process for the Rocket:
· 2L empty plastic bottle
· Cardboard sheets
· Box cutter
· Hot glue gun/Glue
· Black/Grey Vinyl sheets
· Foam cord
· Cotton Balls
· Bubble wrap
(Before, all of these steps make sure you have the vinyl color of your choice onto the cardboard before cutting it off)
1. Firstly, gather materials for building pop bottle rocket
2. Measure the amount of the cardboard sheet needed to wrap bottle
3. Cut cardboard sheet using box cutter
4. Wrap cardboard sheet around 2L bottle and apply hot glue on edge of cardboard sheet so that
