For over 20 years, I had the pleasure—and occasional peril—of sharing the 9NEWS stage with Steve Spangler. He brought science to life with explosions, laughter, and unforgettable moments, but what really made it great television was the connection he created with viewers. The Engagement Effect is the ultimate guide to understanding how he does it.

For decades, I’ve had a front row seat to Steve Spangler’s ability to turn everyday television into something unforgettable. He doesn’t just demonstrate science—he creates shared moments filled with wonder, laughter, and meaning. The Engagement Effect is full of heart, humor, and the kind of insight that turns information into inspiration.
Anchor, 9NEWS Denver
Over the course of 27 appearances on The Ellen DeGeneres Show, I saw Steve Spangler turn science segments into unforgettable shared experiences—moments that sparked joy, curiosity, and connection for millions. The Engagement Effect captures that same energy and breaks down the how and why behind it all. This book is Steve at his best.

We just finished Season 5 of DIY Sci and wow – that last episode was so poignant. I volunteered for the blind, visually paired, and dyslexic from when I was 14 years old. You captured the emotion of learning beautifully. Please let the producers and Steve know that this episode was by far the most memorable!
Steve Spangler is part teacher, part carnival barker, and part master magician… and he’s amazing at all three! When it comes to getting people to fall in love with science, no one does it better.
We just celebrated Steve’s 26th appearance on the show… if that tells you anything. Steve Spangler consistently produces amazing results every time he’s on the show. He understands television and how to show his passion for making science fun.
You’re a total pro on camera! Mentos soda geysers and exploding Pop Rocks made our Science of Candy segments over the top fun. I’ve never heard the crew so excited about a location shoot.
Liz Hostetler, Producer
If you are looking for energy and surprises on television, Steve’s the master at it. Who would have guessed that Steve’s original segment showing something fun to do with a roll of Mentos and a bottle of Diet Coke back in 2005 would make our 9News science guy an internet sensation? Steve Spangler’s approach to doing television is always fun and engaging both for our viewers and our on-air talent. Bottom line… Steve knows how to create fun and viral television experiences that viewers remember.

Take it from someone who has worked with Steve on live television every week for the last 15 years… Steve knows how to create TV moments that viewers remember. Things fizz, pop and explode and so does the e-mail I get when he lights me on fire.
Mark Koebrich, News Anchor
You gave us amazing television on Modern Marvels. One minute you’re talking about the science of super cold temperatures and the next minute we are all standing in the middle of a giant liquid nitrogen cloud. You’re a pro.

The Doctors show staff loved working with Steve Spangler. His demonstrations were the perfect illustration for what we were trying to show our audience… and the visual on camera was great.
Chelsea Wright – Producer
Steve Spangler’s segments on News 10 were great. Ratings were high throughout the entire week. Best of all, I really appreciate his ability to work with our entire on-air morning team. Steve made them look like rockstars… and the viewers loved it.
