Series of three, very hemispheres, glossy black, laid out in a horizontal line on a flesh tone or Band-Aid colored strip of adhesive-like paper or cardboard; each hemisphere with smaller, fractional-sized oval orifice, silver-colored, on end; the whole, mounted on rectangular card and sealed with transparent plastic paper and stapled, with words typed on top of card, "WSR-2 Cap Pistol - World's Smallest Rocket Motors - .008 lb-sec Total Impulse." Two engines on right have open nozzle exits while first on left is closed or sealed, possibly indicating it has not been fired. A special cap pistol device is used to fire the motors by electrical impulses by means of a pyrofuze and pyrotechnic charge in each motor. The cap pistol is not provided with these objects.
