"Art is a medium that has been used to portray societal issues since the beginning of time; and Tomas Saraceno&amp;#039;s bubble sculpture demonstrates the effect humans have on the environment. Stationed in Milan, Italy, Saraceno&amp;#039;s sculpture entitle &amp;#039;On Space Time Foam&amp;#039; is a perfect analogy in the balances that need to be achieved in life. The top of the piece is a bubble-like material that moves as people walk on it. The movement then acts as though this is a living, breathing organism.  Physics was used throughout the piece in order to obtain the perfect consistency on the bubble, and to make sure it retains its shape. The underlying message in this piece is the effect that humans have on the earth, and how the people walking on the top of the sculpture affect those below. Saraceno creates an analogy for how everything is connected, and this bubble sculpture is the perfect medium to demonstrate his ideas."^^<http://www.w3.org/2001/XMLSchema#string>
