"Germs" is the forty-ninth episode of Bill Nye the Science Guy. It aired on April 7, 1995.
This episode is notable for a "Nifty Home Experiment?" (with a black question mark appearing over the usual graphic) where Bill actually warns the viewer not to try it at home. After the experiment is done, he warns the viewer not to try it at home again...only to concede that this is due to the experiment's use of glitter, which makes things very messy. The ending music video is "Just Wast Your Hands" by "Dose of Soap", a parody of Ace of Base's Don't Turn Around.
