F = ma · Thrust
Pressure pushes water down; an equal and opposite reaction pushes the rocket up — Newton’s third law. After the water runs out, the rocket coasts upward before gravity brings it down. A pointed nose reduces air resistance. This model has no wind and holds water quantity and mass constant.
