System and method for filling containers with fluids

1. A method for simultaneously filling balloons with water using an apparatus sufficiently compact to be operated while being held by hand, comprising:

attaching the apparatus to a water supply, the apparatus comprising a fitting comprising an inlet configured to connect to the water supply and a bulkhead joining the at least three branch assemblies, each branch assembly comprising a tube and an automatically-sealing balloon with a neck disposed around and removably attached to the tube;

simultaneously providing water from the attached water supply to each balloon of the balloon-filling apparatus; and

detaching one or more of the balloons from the balloon-filling apparatus using a force comprising gravity each detached balloon and the water contained therein, each detached balloon automatically sealing responsive to detachment.

2. The method of claim 1 , wherein the force further comprises an acceleration manually applied to at least part of the balloon-filling apparatus.

3. The method of claim 1 , wherein the detaching further comprises simultaneously detaching two or more of the balloons from the balloon-filling apparatus.

4. The method of claim 1 , wherein each balloon is connected to the respective tube by an o-ring fastener.

5. The method of claim 1 , wherein the at least three branch assemblies comprises at least ten branch assemblies.

6. The method of claim 1 , wherein each balloon has a neck portion defining an aft gap that separates an inner surface of the neck portion from an outer surface of the tube, the inner surface of the neck portion extending around an inner circumference of the balloon, and the outer surface of the tube extended around an outer circumference of the tube.

7. A method for simultaneously filling balloons with a fluid using an apparatus sufficiently compact to be operated while being held by hand, comprising:

attaching the apparatus to a fluid supply, the apparatus comprising:

at least three branch assemblies each comprising an automatically-sealing balloon with a neck disposed around and removably attached to a first end of a tube; and

a fitting comprising an inlet configured to connect to the fluid source and a bulkhead joining the at least three branch assemblies at respective second ends of their respective tubes;

simultaneously introducing the fluid into each balloon of the at least three branch assemblies; and

simultaneously detaching from the apparatus at least two balloons of the at least three branch assemblies, each detached balloon automatically sealing responsive to detachment.

8. The method of claim 7 , wherein the simultaneously detaching uses a force comprising gravity of each detached balloon and the fluid contained therein.

9. The method of claim 7 , wherein the simultaneously detaching uses a force comprising an acceleration manually applied to at least part of the apparatus.

10. The method of claim 7 , wherein each balloon is connected to the respective tube by an o-ring fastener.

11. The method of claim 7 , wherein the at least three branch assemblies comprises at least ten branch assemblies.

12. The method of claim 7 , wherein each balloon has a neck portion defining an air gap that separates an inner surface of the neck portion from an outer surface of the tube, the inner surface of the neck portion extending around an inner circumference of the balloon, and the outer surface of the tube extended around an outer circumference of the tube.

13. A method for simultaneously filling water balloons using an apparatus sufficiently compact to be operated while being held by hand, comprising:

attaching the apparatus to a water supply, the apparatus comprising:

at least three branch assemblies each comprising an automatically-sealing water balloon with a neck disposed around and removably attached to a first end of a tube;

a fitting comprising an inlet configured to connect to a fluid source and a bulkhead joining the at least three branch assemblies at respective second ends of their respective tubes, the fitting and the at least three branch assemblies at least partially defining fluid paths extending from a common point within the fitting to the inside of each balloon container of the at least three branch assemblies;

simultaneously introducing water into each balloon of the at least three branch assemblies; and

detaching from the apparatus one or more of the balloons, each detached balloon automatically sealing responsive to detachment.

14. The method of claim 13 , wherein the detaching further comprising simultaneously detaching two or more of the balloons using a force comprising gravity of each detached balloon and the fluid contained therein.

15. The method of claim 13 , wherein the detaching further comprising simultaneously detaching two or more of the balloons using a force comprising an acceleration manually applied to at least part of the apparatus.

16. The method of claim 13 , wherein each balloon is connected to the respective tube by an o-ring fastener.

17. The method of claim 13 , wherein the at least three branch assemblies comprises at least ten branch assemblies.

18. The method of claim 13 , wherein each balloon has a neck portion defining an air gap that separates an inner surface of the neck portion from an outer surface of the tube, the inner surface of the neck portion extending around an inner circumference of the balloon, and the outer surface of the tube extended around an outer circumference of the tube.
