Abstract: A tool for tying knots in the necks of inflatable objects, such as balloons. The tool is an elongated member having two side surfaces, a top surface, a bottom surface, and opposing tapered ends. Each tapered end contains a recessed area in the top surface. There is a receiving slit in each recessed area. The distal portion of the receiving slit may have a "V" shape to increase ease of access of the balloon neck. The tool is made of a lubricating plastic, such as a mixture of ABS rubber and at least one of high density polyethylene, high density polypropylene, and silicone in order to decrease the friction between the tool and the ballon. To further decrease friction between the tool and the balloon, the tool contains small protrusions or dimples which decrease the surface area of contact.
