A lamp chimney lift pump
Use a straight-sided lamp chimney as a pump cylinder. Fit a two-hole stopper into the chimney for a piston. If the stopper is a little small wrap some string around it to make a tight fit. If it is a little large you can make it lesser with sand paper. Through one hole put an iron or brass rod for a piston rod. Wrap the other hole on top of the stopper with a small flap of rubber or soft leather cut from an old shoe. This will be the piston valve. It can be held in place with a tack pushed into the stopper.
