Abstract
Abstract A child''s building toy of various basic building units is disclosed each of which building units is in the form of an elongated double-ended member having at least one bend. Each basic building unit further includes a connector upon each end to allow a child to interfit and interconnect the basic building units to construct and interconnect an arrangement of basic building units of his own design comprising any number of units to the maximum number available. The basic building units are hollow to allow water to flow therethrough, and at least some of the units include apertures to allow the water to issue from them as a spray upon children climbing and otherwise playing upon an interconnected arrangement of the basic building units.
