There are several materials you can use. Plastic assignment folders make an excellent fin because they are light weight and more durable than paper. Corriflute (Correx) is also a great material as it to is sturdy. (i am assuming you are building a 2 liter water bottle rocket) Avoid using paper and card board as the water can damage the fins making them anti-productive.
The tail fin serves to guide, steer and stabilze the missile.

Shark fin soup has been eaten in China since the Ming Dynasty. It is considered to be one of the eight food treasures from the sea.
it means la fin
There does not appear to be a "best" size. It depends on a number of factors, to include the bottle used (brand of drink & manufacturer), type of rocket, distance aiming for. One common element to consider is drag. Larger fins have greater surface and mass which will directly affect the altitude your rocket can reach.
A regular rectangular shaped fin makes the best flight time.
Because it is light weight, and easy to fold into the fin shape.
Right angle fins is the best

The definition of fin on a rocket would be, a thin, protruding piece of metal whose function is to provide aerodynamic stabilization when the rocket is in flight.
fin and tip (cone).
A longer fin has increased aerodynamic drag. The geometric relationship between the drag caused by the fins and the center of gravity of the rocket determine the stability of the rocket in flight. Less aerodynamic drag means the rocket can go higher or farther, but it also means the rocket is less stable in flight. This tradeoff has to be considered in the design of the rocket.
It helps stabilise the flight
Yes, the size of the fins on an AA bottle rocket does matter. Larger fins can provide more stability and control during flight, helping the rocket maintain a straight trajectory. However, if the fins are too large, they can create excessive drag, which may hinder the rocket's performance. Ideally, fin size should be balanced to optimize stability without significantly increasing drag.
A fin on a rocket is a flat surface projecting from the body that helps stabilize the rocket's flight by providing aerodynamic forces to keep it on a desired trajectory. Fins increase stability by creating drag and preventing the rocket from spinning or veering off course during ascent.
They don't have a shark fin. They have a completely different type fo fin all together
