I've attended a few performances and demonstrations by this dynamic husband and wife duo. Dr. Friedman is a PhD chemist who offers really upbeat and exciting science programs for kids of all ages. I've seen their liquid nitrogen show and the CSI: Chicago forensic program and the kids had a blast using their newfound science skills to catch the criminal. I really liked the flash-frozen ice cream served at the end of the liquid nitrogen program.
Pros: Fun, fast-paced, intelligent
Cons: Not all programs work in all venues
