a flat surface would have air resistance and a cone doesn't
yes, it helps it fly faster, trust me, I've tested all kinds of rocket tests. - Mr. Burn
Yes because if the cone is not straight it will make the rocket go offside; wonky, and you would not fly straight. It is also harder to control
Most model rockets have a nose cone that is either a solid block of balsa wood, or a hollow plastic shell. Some rockets require that a small amount of weight be added to the front end of the rocket to make it fly in a stable (straight) manner. In these rockets, nose weight is often added inside of hollow nose cones - common material for weight is a small blob of modelling clay or a solid blob of glue. When nose weight needs to be added to a rocket with a solid balsa nose cone, it is common to add a small metal washer to the bottom end of the nose cone (which will end up inside the body tube when the rocket is assembled.) The amount of nose weight needed in the size rockets commonly sold in hobby stores is usually between 0 and 20 grams.

A good balance of propulsion and weight, and make sure that it has a good aerodynamic structure, because sometimes the nose of a rocket tends to be in a shape that creates more wind resistance.
Rockets have pointed noses to reduce air resistance as they travel through the Earth's atmosphere during launch. The pointed shape helps to minimize drag and allows the rocket to move more efficiently through the air, ultimately increasing its speed and reducing fuel consumption.
Nosecones can be almost any shape and any material imaginable. Even a cube shaped nose cone can fly straight with ease. Typical cone shapes include "ogive" and "conical". They are typically made of balsa wood, plastic, and fiberglass/carbon fiber. An odd shaped nosecone can be offset by fins that are adequate to compensate for the the shape of the cone. One high-powered rocket, named "Suicide King" as seen on youtube, actually flew without a nose cone for a nearly perfect vertical flight.
it doesnt
Nose weight often helps to bring the wings into flying attitude.
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.
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)
The rocket never flies.
