"Do-It-Yourself Science" is the eighty-seventh episode of Bill Nye the Science Guy. It aired on November 21, 1997.
The second of two clip shows, this episode consists of past "Nifty Home Experiment", "Try This", and "Clever Science Trick" segments, using Ritchie and his family as a framing device, ultimately leading to the post-episode music video being done by "Nye and the Family Crust". While the actual song is a parody of Hell, by the Squirrel Nut Zippers, the "band name" references Sly and the Family Stone.
