Creed calls the installation “Half the air in a given space“, and, as he explains, the situation is normal, because, “as usual, the space is full of air; it’s just that half of it [is] inside the balloons.” Interestingly, visitors say that they often get lost in the balloon-filled room and then all of a sudden run into someone as awe-struck as they are; or how they think they’re moving towards the center of a room, but end up hitting a wall.
First created in 1998, the installation since then was presented in a number of different museums. Every time the installation ends, visitors are allowed to take a balloon home, which works out nicely as a partial deconstruction.
