He’s a bestselling author, STEM educator, and television host who has spent thirty years turning science into something nobody wants to miss.
He’s the guy behind YouTube’s first viral science video — the one that taught the world what happens when you drop Mentos into a bottle of Diet Coke. His videos have since generated more than 4.5 billion views across social media. That’s billion. With a “b.”
His books and experiments have become go-to resources for parents and educators worldwide — the kind of stuff that makes kids actually want to know what happens next.
If you’ve seen the enormous mess he repeatedly made on The Ellen DeGeneres Show, you already know why Ellen calls Steve the science teacher you always wanted — because the fire department shows up twice a year.
Ladies and gentlemen, please welcome Steve Spangler.
Steve Spangler created one of YouTube’s first viral phenomena: the Mentos and Diet Coke geyser. His videos have since crossed 4.5 billion views.
He’s a two-time Emmy Award winner and the host of the nationally syndicated science series DIY Sci on FOX and CW affiliates, also streaming on Amazon Prime. He’s been a guest on The Ellen DeGeneres Show 27 times, where Ellen called him America’s Science Teacher.
Across more than thirty years on camera, Steve has logged over 2,100 television appearances. He’s delivered more than 1,500 live segments on KUSA 9NEWS Denver (NBC), with national appearances on the Today Show, Good Morning America, History Channel, Food Network, Fox & Friends, CNN, HLN, the Weather Channel, and others.
Steve specializes in hands-on, on-camera science that lands in under four minutes: kitchen chemistry, holiday and seasonal demos, weather science, viral experiments, and the science behind everyday things. He’s the producer’s call when a segment needs something visual that won’t fail on live TV.
Steve serves as STEM Educator in Residence at High Point University and is the bestselling author of nine books, most recently The Engagement Effect (Simon & Schuster, 2025).
