A rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust by ejecting a jet of fast moving fluid from a rocket engine. The action of the fluid against the inside of combustion chambers and expansion nozzles is able to accelerate the fluid to extremely high speed, and this exerts a large reactive thrust on the rocket (an equal and opposite reaction according to Newton's third law).

A root canal is the removal of a nerve from a tooth. In removing the nerve the tooth can not feel pain. The tooth is hollowed out, the nerve is removed, and then internal bracing is inserted in to the tooth for support. Next a filler of o porcelain compound is put into the tooth to make it solid and create the normal contour of the original tooth surface. It would be painful without an anesthetic while the first stage is completed. Once the nerve is removed the tooth has no more ability to feel pain.
