A backyard science trick turns into a full-blown soda volcano once the shovels come out.

The channel My EXPERIMENTS built its latest upload around a simple dare: what happens when you dig pits into the dirt, sink bottles of Coca-Cola, Mirinda, and Pepsi down to their necks, and drop Mentos into all three at once? The video, titled “Experiment: Cola, Mirinda, Pepsi and Mentos Underground,” follows the well-worn DIY-experiment format that flooded YouTube in late 2019 and early 2020 — no lab coats, no scientists, just a hole in the ground and a phone camera pointed at it.

• The creators dig outdoor pits and bury or trench three separate soda brands — Coca-Cola, Mirinda, and Pepsi — before triggering the reaction.
• Mentos candies are dropped into each buried bottle simultaneously, producing rapid, high-pressure geysers of colored soda shooting out of the excavated ground.
• The effect is driven by nucleation, not a chemical reaction: microscopic pits on the Mentos surface release dissolved carbon dioxide from the soda almost instantly.

Current Developments Within the Pit

Despite the “underground experiment” framing, there’s no lab, no control group, and no research team. This is the classic Diet Coke-and-Mentos stunt relocated from a driveway to a dug-out trench in the soil. The physics is the same one that’s been demonstrated on countertops for over a decade: the rough, porous surface of a Mentos mint is covered in tiny craters that dramatically increase the surface area exposed to the carbonated liquid, giving dissolved CO2 bubbles thousands of new places to form at once.

That’s nucleation, not a fizzy chemical reaction between candy and cola. Drop enough Mentos in fast enough, and the gas escapes so quickly that the bottle can’t vent it through the neck alone — it blasts liquid out with it, sometimes several feet into the air. Burying the bottle up to its neck, as the video does, just channels that pressure straight up out of the hole like a makeshift geyser vent.

Three Sodas, Three Colors

The choice of Coca-Cola, Mirinda, and Pepsi isn’t random — it’s a visual trick as much as a scientific one. Cola’s dark brown spray, Mirinda’s bright orange stream, and Pepsi’s near-identical cola tone side by side give the footage contrast and let viewers compare eruption height and volume across brands, even though the underlying carbonation chemistry is nearly identical in all three.

Bury the bottle, drop the Mentos, and the ground itself becomes the geyser.

That side-by-side format is exactly what separates this clip from the standard tabletop version most people grew up watching: turning it into an outdoor dig gives it the same rough, homemade appeal you’d find in a video about building a shelter by hand in the woods — no polish, just a camera, some dirt, and a clear payoff.

Drivers of the Emerging Trend

Soda-and-Mentos content has been a YouTube staple since the mid-2000s, but the “underground” or “volcano pit” variation gave it new life heading into 2020. Channels leaned into the geological framing — pits, trenches, “eruptions” — to borrow visual language from actual volcanic footage, the same instinct that makes clips like unusual volcanic phenomena videos pull big numbers: viewers are drawn to anything that looks like the earth itself is reacting, even when the real cause is a candy’s surface texture and a bottle of soda.

My EXPERIMENTS didn’t invent the format, but the channel’s version leans hard into the multi-brand comparison, letting the three geysers erupt close enough together that the footage reads like a controlled test even though nothing about the setup is scientific. That’s the whole appeal — it looks like an experiment, plays like a stunt, and works because the physics never fails.
