For a typical water rocket, it doesn't matter much. Three squares or triangles, about four to ten square inches in size, 120 degrees apart, as far below the center of mass (balance point) as you can put them, will do well enough. Use any stiff plastic and a lot of Duct Tape. Try to glue them on as close to vertical as you can - or if you want the rocket to spin, try tilting them all the same way a couple degrees. (A small amount of spin may help stability; a lot will cut down your altitude greatly). A water rocket isn't going to be very stable at the best of times, since the water tends to slosh around, and the fins can't do much about that. (A little bubble bath in the water, shaken up to get some foam, may help.)
yah but whatever else u wnt man(:
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.
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
To help a bottle rocket fly straight, ensure that it is launched on a stable and upright surface. Check that the fins are properly aligned and secure. Also, make sure the launch angle is between 60-80 degrees for optimal trajectory.
Streamlining the shape of the rocket, reducing surface roughness, and ensuring a tight seal between components can all make a water bottle rocket more aerodynamic. Additionally, fins can be added to stabilize the rocket's flight and reduce drag.

the best fins for a bottle rocket is having four fins located at the bottom of your bottle rocket the shape of long triangles ! ! ! :) hope it helps !
You use fins and a nose cone on a bottle rocket because the cone reduces the drag on the rocket, and the fins help stabilize the rocket.
Bottle rockets have fins to provide stability during flight. The fins help keep the rocket flying straight by preventing it from tilting or spinning, which can affect its trajectory. This design allows the rocket to travel in a more controlled manner.

Right angle fins is the best
Yes as it control the dirctions of the rocket.

Oh, dude, the best angle for bottle rocket fins is typically around 45 degrees to provide optimal stability during flight. But hey, feel free to experiment and see what works best for your rocket. Just don't blame me if it goes off course and lands in your neighbor's backyard!
Fins are used to help keep a rocket stable. The only way to find out if more fins will make it more stable is by testing it.

Angle the fins so it spins, like a screwdriver
