Jet propulsion construction toy assembly

A jet propulsion construction toy assembly comprising:

• a movable brick assembly;
• a container mounted on said brick assembly, configured with an inner receiving space, and having an outwardly extending tubular nozzle in spatial communication with said inner receiving space;
• a launching unit including
• a launching seat formed with an opening, permitting extension of said nozzle of said container thereinto through said opening, and having an inlet in spatial communication with said nozzle of said container when said nozzle of said container is retained in said launching seat, and
• an actuator mounted movably in said launching seat, and operable to move between an engaging position and a releasing position, wherein, when said nozzle of said container extends into said launching seat, said actuator engages said nozzle of said container when in the engaging position such that said nozzle of said container is retained in said launching seat, and disengages said nozzle of said container when in the releasing position such that said nozzle of said container is released from said launching seat;
• and
• a fluid supplying unit including a barrel adapted for receiving fluid that includes air and liquid, a pump, a first conduit interconnecting said barrel and said pump, and a second conduit interconnecting said pump and said inlet of said launching seat of said launching unit;
• wherein, when said nozzle of said container is retained in said launching seat of said launching unit, said pump of said fluid supplying unit is operable to pump the fluid out of said barrel through said first conduit into said inner receiving space in said container through said second conduit, said inlet of said launching seat of said launching unit and said nozzle of said container such that said inner receiving space in said container is filled with the fluid pumped by said pump, and subsequently, when said actuator is moved from the engaging position to the releasing position, jet of the fluid from the inner receiving space in said container through said nozzle forms a propulsion force to drive movement of a combination of said brick assembly and said container away from said launching unit.
