2006 / Video / Creator-led practical-effects spectacle

Diet Coke + Mentos

One hundred and one bottles, five hundred Mentos, and a backyard fountain that made the web want to try science at maximum volume.

The original is off-site. HAHrchives preserves the story and a route back to it.

What happened

In lab coats and goggles, the pair set off a cascading field of Diet Coke geysers with carefully timed Mentos drops. It was homemade spectacle with the precision of a miniature Bellagio show and the payoff of a very fizzy magic trick.

Where it came from

Maine creators Fritz Grobe and Stephen Voltz, working as EepyBird, spent six months developing a choreographed fountain experiment. They filmed Experiment #137 in one take and published it on EepyBird.com on June 3, 2006.

Why it mattered

EepyBird showed that a small, creator-owned experiment could become huge without pretending to be an ad or a television show. It is a pure early-web delight: practical effort, visible wonder, and exactly the kind of thing you had to send to someone.

How it spread

The official post drew thousands of viewers within hours; television invitations and NPR followed that first week. Its simple, repeatable premise set off a worldwide wave of soda-and-candy experiments and early viral-video remakes.
