Abstract: A method whereby a seal, such as a door or window seal including a joint or seam, is tested for leaks. An aerosol can has an environmentally safe propellant and a liquid therein that exits the can as a tracer mist, which tracer mist may contain a disappearing dye. The can is positioned on one side of the seal being tested and is sprayed at this side with the opposite side observed, either visually, or with the aid of a marker strip, in order to determine if any of the tracer mist passes from the one side of the seal to the other side.

Abstract: A tethered ball toss game is described in which a number of tethered balls arranged at both ends of a series of cords and secured to the ends of the cords by knots are tossed from a prescribed distance toward a number of horizontal bars positioned between upright supports which are retained in perpendicular angularity to the underlying support surface by bottom supports. Each of the horizontal bars are relocatable in a vertical direction along the side supports to other pre-determined points for engagement with the side supports by engaging a retractable latching member into a cooperating hole so that the bar is secured in the desired position. In this fashion the distance between the bars can be altered to vary the difficulty and skill levels of the game. Alternative embodiments of the game are also contemplated where the length of the bars is varied by changing the shape of the side supports to accommodate shortened horizontal bars.
