Three Drops

Three Drops is a full body immersive simulation that allows visitors to interact with water at three size scales using their shadows. At each scale, different physical forces can be observed. At the macro (human) scale, where gravity is the noticeable force, visitors are showered with water drops from a simulated shower. At the microscale--one thousand times smaller--where surface tension becomes more apparent, visitors play with a beach-ball sized water drop.

Zoom into a Pencil Line of Graphene with an Atomic Force Microscope (AFM) - Illustration

This illustration shows how an Atomic Force Microscope (AFM) is used to image a line of graphene made by a pencil. The scale spans ten orders of magnitude, from the microscope and pencil to the atoms that compose the scanning probe and pencil line. As the viewer zooms into the line, graphite flakes, and eventually a single layer of graphene, become visible. On the AFM, a silicon cantilever with a sharp atomic tip and a laser with a photodiode measure the up and down motion as the probe maps out the graphene sample.

The Scale of the Universe Zoom

This interactive animation is a modern version of the classic powers of ten video. It takes you all the way from the (estimated) outer reaches of the universe down to the length of a Planck. Somewhere in the middle, the animation let's you explore the nano-scale. Click on different objects as they zoom by to learn more.
