SciJinks

Johnny Galecki, best known for his portrayal of socially awkward physicist Leonard Hofstadter on "The Big Bang Theory," uses actual science to perform outrageous stunts and practical jokes as host of "SciJinks." Joined by partners in "prankology" Tamara Robertson and Jason Latimer, Galecki draws from chemistry, physics, technology, engineering and more to test science on unsuspecting marks. The pranks not only contain mind-blowing experiments, but also a heaping dose of chaos, fun and humor. The goal, Galecki says, is to celebrate students who envision a career in a science field and inspire other youngsters to follow in their footsteps.
