The third annual "Sanford Science Fair" is this Saturday at their research facility, just off I-229 and 60th Street North.

The event runs from 9 am until 5 pm, and is free of charge.  Various seminars and demonstrations are planned for the entire day.

Dr. Jill Weimer stopped by the Main Street Cafe Wednesday morning to visit with Chad about the event.
