Keith & Russ welcome K.W. Hipps, Professor of Chemistry and Materials Science at Washington State University. Hipps tells us some of the childhood "mad scientist" experiments that inspired him to become a scientist. He also introduces us to "tunneling," in which electrons "slide" through an electron cloud without losing any energy. Visit the Hipps Tunneling Group at WSU: http://public.wsu.edu/~hipps/
