The Mentos and Diet Coke geyser was one of the first videos to go viral on YouTube, and it showed millions of people how to turn a bottle of soda into an eruption in their own driveway. YouTube noticed. The company funded 60 episodes of The Spangler Effect as part of its original-content program, back before “YouTube creator” was a job anyone could name. Steve’s catalog has since grown to more than 1,800 videos, and across all his channels and platforms his science videos have passed 4.5 billion views.

Steve grew up in a family of magicians, and he rarely gets the chance to talk about how sleight-of-hand shaped the way he teaches science. This PBS conversation on Side by Side, taped in the theater at High Point University, is the exception. It digs into how a magician’s instincts carry into a classroom that kids don’t want to leave.
