The “Chemists in the Library” program was coordinated by Phil Buhlmann, associate professor of chemistry at the Univ. of MN and chair of the Outreach Committee of the MN section of the American Chemical Society.  Other chemists who participated were Dave Blackburn, chemistry professor at Century College;  Wayne Haag, retired Century College chemistry professor;  and Linda Nanko-Yeager, a retired chemist at pharmaceutical companies on the East Coast.

Volunteers assisting were Keiko Buhlmann, Phil’s wife;  Kelsey Boyle, a U of M chemistry student;  Helena Qi, a chemical physics major at Wellesley College in Boston who is in the Twin Cities this summer doing research work with a U of M professor;  and Randy Siedschlag, a U of M chemistry graduate student.

The chemists and assistants demonstrated chemical reactions, including:
•       Color-changing chemical reaction using dry ice
•       Make your own super ball
•       “Balloon on a Stick”
•       “Chemistry in a Bag”  -- endothermic (cold) and exothermic (heat) reactions
•       A “CSI” (crime scene investigation)-type experiment with changing color
•       Make your own “hamster toothpaste”
•       Make your own play putty
