Register, Berg, and Turner WOW Students at University Science Expo

Almost 1,000 middle school students and teachers from Mercer County schools flocked to Princeton University to explore cutting-edge science and technology with university researchers during a campus-wide exposition on March 17. Among the presenters was Professor Rick Register, who explained to students the changing properties of molecules using bouncing rubber balls and dry ice. Also involved was postdoctoral student Steffen Berg, who used a soap bubble machine to illustrate some features of the research he's doing. Finally Anthony Turner, a senior in chemical engineering, manned an exhibit on alternative energy sources.
