Bill Nye the Science Guy was a 1990s children's science television show hosted by Bill Nye, known for fast experiments, catchy songs and energetic explanations of everyday science. Its opening became one of the most recognisable TV intros of the decade, and short clips from it later spread through YouTube edits, TikTok videos and online soundboards. The intro still works because it instantly signals a fun, confident science lesson, even when creators use it ironically for a failed experiment or a joke that has nothing to do with science.
