Caltech president Thomas F. Rosenbaum accepts the ALS Ice Bucket Challenge from MIT president Rafael Reif. Dr. Rosenbaum gets doused in the flume in the Earth Surface Dynamics Laboratory (http://geomorph.caltech.edu/earth-sur...) of Michael Lamb, Caltech professor of geology. Dr. Rosenbaum challenges Worcester Polytechnic Institute president and Caltech alumna Laurie Leshin (MS '89, PhD ’95) and University of Chicago provost Eric Isaacs. The water used in the flume's experiments is recycled; it gets pumped from the flume's floor back up to the top of the incline. No water was wasted in the making of this video.
