Animated abstract images create a portrait of matter in perpetual decomposition. Aeolian Landscape is an exhibit in which a miniature wind-swept desert landscape is recreated by an electric fan and finely ground sand that mimics the process of wind picking up and depositing small particles. Visitors can change the direction of the fan, influencing the shape of the dunes. At the Balancing Ball exhibit, a plastic beach ball floats mysteriously several feet above a large plastic cone. Upon closer inspection, the ball is found to be floating on a stream of air blowing out of the cone; visitors interact with the ball, changing its position in relation to the air flow. The Chaotic Pendulum exhibit contains a deceptively simple set of pendulums in a steel and Plexiglas case. The visitor twists a protruding knob, expecting the resulting motion to be fairly predictable. But the device's motion is chaotic, extremely complicated and long-lived. Artist Sheldon Brown creates an urban/suburban/rural environment in which the visitor literally "paints" the flying landscape with highways, buildings, and automobiles. This exhibit was part of the Virtual Unreality exhibition. The Exploratorium's Ron Hipschman shows how a double disk with a string attached is a great way to study the physics of motion. Then Captain Yo and Doc Popular astound with amazing yo-yo tricks. An clip of the Aeolian Landscape exhibit by artist Ned Kahn. Blowing air sculpts sand into an ever-changing landscape. The concept of space-time--perhaps Einstein's most fundamental contribution to our understanding of the universe--will be explored using special red lasers. Using a simple ball-bearing model, Exploratorium Senior Scientist Dr. Paul Doherty demonstrates Brownian Motion and explains how it proves the existence of atoms. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient: Clothespins!
