Abstract
A brush-type system for attracting high volumes of fluid through capillary action and retaining such fluid by surface tension pending usage; and, more particularly, a brush-type system (20) of the foregoing type for blowing bubbles including: a hollow tubular body member (21); a plurality of flexible bristles (22) disposed in a hollow tubular array (24) and secured in coaxial end-to-end relation to the body member (21) and in closely spaced surrounding relation to the tubular array (24) of bristles (22) with the free ends of the bristles (22) projecting slightly beyond the free end of the sleeve (25). The bristles (22) are preferably slightly sinuous and have longitudinally extending radial flutes (30). The bubble blowing system (40) preferably includes an essentially spill-proof receptacle (41) for receiving the brush (20) and enabling loading of the bristles (22) with a bubble forming solution without risk of deformation of the bristles (22).
