Contemporary art doesn't get much more fun than this! First created in 1998 with white balloons and then redone many times over, Half the Air in a Given Space is an interactive installation, by British artist Martin Creed, that's comprised of hundreds or thousands of balloons of the same color. As the name suggests, half a room's entire volume is filled with air-inflated balloons and then visitors are encouraged to walk through. SO NEAT. I want to go there!!!
