What is the best shape for a rocket?
At supersonic speeds (faster than the speed of sound), the best shape is a narrower and sharper point. Rockets with a larger diameter have more drag because there is more air being pushed out of the way. Drag depends on the cross-sectional area of the object pushing through the air.
How high can a water bottle rocket go?
The bottle usually has a nose cone for streamlining and fins for stability. Water rockets are easily capable of 100 m high flights, but advanced hobbyists have combined bottles and staged bottles for flights over 300 meters high. Water bottle rockets are ideal for teaching Newton’s laws of motion.
