“Cutting it Down” is a cart demo that communicates scale through a hands-on activity. Visitors learn that the nanometer size scale is very, very small—and that we can’t use macroscale tools to manipulate nanoscale materials. During the program, visitors are challenged to cut a small strip of paper in half as many times as they can—or until they reach the nanoscale, which ever comes first.
