Have you ever wondered what it would feel like to walk on clouds? Well, now you can. Argentine installation artist Tomás Saraceno's new exhibition entitled, "On Space Time Foam," lets you feel like you're breaking the laws of gravity. Composed of three levels and constructed out of thin clear film, the colossal 1,312 square foot installation is suspended 65 feet in the air at the HangarBicocca in Milan.
