Join Exploratorium Senior Scientist Paul Doherty and visiting scientist Alfredo Mateus for an exploration of hands-on demos. In today's webcast, Paul and Alfredo will be looking at a voice activated chemical reaction and what happens when you heat plastic in water! This is a time-lapse movie of a chain reaction activity presented at the Exploratorium booth during Maker Faire 2009. Participants were asked to build a portion of a collective chain reaction contraption, which was set off twice during the day. Photos were taken every 30 seconds and then joined in a 24 fps movie.

Cheer on the competitors in this zany science cook-off. This week's secret ingredient was nuts and bolts In conjunction with this summer's special exhibition Reflections, Exploratorium Senior Scientist Paul Doherty joins us for a hands-on Webcast. What effect does looking through two mirrors have on an image? Or three mirrors? Snow Mirror is the first in a series of pieces that celebrate slowness and black and white, in this piece the image of the viewer is created by the congregation and accumulation of white snow flakes in areas of the image that are brighter. The result is projected on a transparent silk fabric which creates a feeling of the flakes being suspended in space. Artist Daniel Rozin will be featured in the Exploratorium's 2009 exhibition, Reflections. Shaking Time Mirror is the forth of the "Time Series" Software Mirrors. This series of software mirrors examines notions of time, scanning, motion and stagnation. In Shaking Time Mirror only areas of movement on the screen are refreshed with current video, the rest of the screen ages and turns into a gray stagnant crust. When a viewer moves in front of the piece the crust flakes of and revels the full colored image of the viewer, which gradually grays back. Artist Daniel Rozin will be featured in the Exploratorium's summer exhibition, Reflections. Self Centered Mirror is an arrangement of 34 vertical panes of mirror. It has a retro-reflective behavior, this means that anyone standing in front of this mirror will see themselves reflected on all 34 panes, The mirror will also remove anyone else in the space from being reflected. This piece lifts the last obstacle from in the quest to total narcisism. Artist Dan Rozin will be featured in the Exploratorium's summer exhibition, Reflections. Mirrors Mirror creates the viewers' image by directing 768 small mirror tiles in a way that reflects different portions of their image. The piece is made of 24 columns of "pixels" that form a concaved curved surface that is aimed at the viewer. Brighter pixels reflect the upper body of the viewer and the wall behind him and dark ones are aimed lower. Artist Daniel Rozin will be featured in the Exploratorium's 2009 summer exhibition, Reflections. Join us for a live Webcast exploring eggs! Eggs are cells – the largest cells. We all come from eggs. Come explore the wondrous workings of eggs with staff biologists including naked eggs, de-shelled to demonstrate osmosis, sea urchin egg fertilization, life inside an egg using chick embryos, and other ova-vations to discover their amazing properties.
