BUCKFIELD – The lab-coated duo who created spectacular, fizzy fountains by dropping Mentos candy into bottles of Diet Coke has a new experiment brewing.

This one involves sticky notes.

The Buckfield-based performers plan to create waterfalls using the ubiquitous office supply.

On Friday, Fritz Grobe and Stephen Voltz plan to unveil a teaser video of their new creation at the Comic-Con International gathering in San Diego.

Next month, they plan to host a Los Angeles film crew in Buckfield to document the new experiment. That video is scheduled to debut Sept. 5 on cable’s ABC Family network for the premiere of “Samurai Girl.” The video will be unveiled at the same time on the pair’s Web site, EepyBird.com.

The teaser is already posted there, offering only vague hints of what Grobe and Voltz are planning.

“It’s going to be a little fancier than our other videos,” Grobe said Wednesday in a phone interview from the city of Edmonton in Alberta, Canada, where he and Voltz are performing.

But it will be the same guys in the same white coats that have been featured around the world.

“It’s still us,” Grobe said.

The first video, posted on their site in June 2006, became a phenomenon.

Titled “Experiment #137,” it showed the deadpan pair setting off geysers of soda in choreographed streams that resembled the fountains outside Las Vegas’ Bellagio.

“There’s a little comedy in it,” Voltz said in a 2007 interview with the Sun Journal. “There’s a little science in it. There’s a little dance in it.”

The combination seemed to work at a moment when videos – rather than jokes or photos – were first being passed along the Internet.

Within days, they were called by producers for “The Late Show with David Letterman.” Within weeks they’d performed on the “Today” show.

Since then, they have been invited to perform with the Blue Man Group. They were featured in videos by the Barenaked Ladies and Weezer. And after the sale of Mentos took a leap, the company hired them to perform at a factory in Holland. There were also company dates in Paris and Istanbul.

They’ve exploded 4,000 bottles of Diet Coke and drenched over 24,000 Mentos.

And they’re doing more.

On Wednesday, they were in the middle of a week-long gig at a festival in Edmonton, spilling more candy-coated soda.

Perhaps Grobe and Voltz came up with a new gag so they could perform without the mess.

“It takes two-and-half hours to set up, two-and-a-half minutes to set off and one hour to clean up,” Grobe said.
