1. A pop up device for forming a curtain, comprising: a box, having an inside portion; andan extendable assembly, having a connection part that is connected to the box, and having an extending part that in a retracted position where said extendable assembly fits completely within the box, and said extendable assembly extends to an extended height that extends above the box,wherein said extendable assembly includes first and second legs which fold to said retracted position, and extend relative to said box between said retracted position where said first and second legs fit inside the box, and a fully extended portion where said first and second legs are fully extended where they are at a fully extended height, and a spring that spring biases said first and second legs into said fully extended position, and where at said fully extended height, said springs have minimum tension, thereby assisting extending to said fully extended position, said extendable assembly including crosswise ribs extending between said first and second legs at multiple locations between said first and second legs, said crosswise ribs including clips thereon and holding a sound deadening material. 2. The device as in claim 1, wherein said sound deadening material is at least 10 ounce draperies or thicker which forms an acoustic curtain in said upright position, and folds to fit fully within the box in said retracted position. 3. The device as in claim 2, wherein said legs lock in at least one position, and further comprising at least one pull string which unlocks the legs from their locked and fully closed position. 4. The device as in claim 2, wherein said legs are each formed of multiple leg segments, each leg segment which hinges at opposite ends thereof, and where said hinges causes said leg segments to fold relative to one another with each leg moving in an opposite angular direction to each adjacent leg. 5. The device as in claim 2, further comprising a top to the box, which closes to hold said extendable assembly therein, fitting completely within the box in said retracted position. 6. The device as in claim 5, wherein the top to the box is hinged at two different locations, allowing the box to open including both the top of the box, and a portion of a side of the box. 7. A method of temporarily acoustically shielding an area, comprising: storing an acoustic curtain in a folded position inside a box, said acoustic curtain made of a sound deadening material;extending said assembly by pulling an a release holder, and pulling said assembly to a first height using said release holder;wherein said pulling on said release holder causes first and second folded legs to unfold from said retracted position, and to extend relative to one another from said retracted position where said first and second legs fit inside the box, to said first height;whereby a spring bias on said legs causes said legs to automatically extend to a fully extended portion where said first and second legs are at a fully extended height after reaching said first height, and where at said fully extended position, said spring bias has minimum tension, thereby assisting extending to said fully extended position,wherein said acoustic curtain is connected to crosswise ribs extending between said first and second legs at multiple locations between said first and second legs; andwhen in said extended position, using said acoustic curtain for carrying out an acoustic shield. 8. The method as in claim 7, wherein said legs lock in at least one position which is a fully retracted position, and further comprising at least unlocking the legs from their locked position using said release holder. 9. The method as in claim 7, wherein said legs are each formed of multiple leg segments, each leg segment which hinge at opposite ends thereof, and where said extending comprises unfolding said leg segments relative to one another with each leg moving in an opposite angular direction to each adjacent leg. 10. The method as in claim 7, further comprising using a top to the box to close the box with said acoustic curtain therein, fitting completely within the box in said retracted position. 11. The method as in claim 10, wherein the top to the box is hinged at two different locations, allowing the box to open including both the top of the box, and a portion of a side of the box. 12. The device as in claim 3, wherein said pull string extends outside a perimeter of the acoustic curtain when the extendable assembly is in the retracted position, and said pull string fully within the inside of the perimeter of the acoustic curtain when the extendable assembly is in the extended position. 13. The device as in claim 1, wherein the springs are biased to automatically extend the extendable assembly into the fully extended position once the extendable assembly has been manually brought to halfway extended. 14. The method as in claim 10, further comprising locking said legs in a closed position, and further comprising using at least one pull string which unlocks the legs from said closed for extending said box, said pull string extends outside a perimeter of the acoustic curtain in the retracted position, and is held within the inside of the perimeter of the acoustic curtain in the extended position. 15. The method as in claim 10, wherein the springs are biased to automatically extend the assembly into the fully extended position once the assembly has been manually brought to halfway extended. 16. The method as in claim 10, wherein said sound deadening material is at least 10 ounce draperies or thicker, which forms an acoustic curtain in said upright position, and folds to fit fully within the box in said retracted position.
