Ann Arbor, MI
My name is Larry Biederman, and I am a science and math teacher. I have been doing science shows for museums, schools, libraries, and other organizations since 1998. I even asked my wife to marry me during a science show at a museum. My liquid nitrogen show is my most popular show. Children and parents both love this show as I demonstrate the amazing properties of a super cold liquid which ends with the dramatic "big poof". My fee is just $250 per show.
