- After his gargantuan, record-breaking elephant-toothpaste experiment in David Dobrik’s backyard shot to viral fame, the science YouTuber Nick Uhas told Insider what it was like to clean up the aftermath.
- Uhas said he and Dobrik decided to triple the size of their previous attempt, which became the most viral TikTok of 2019, to secure their title ahead of the fellow YouTuber Mark Rober’s experiment.
- The two are “kind of hoping it turns into a little bit of a foam arms race,” Uhas said, but a contender hasn’t arrived – yet. In the meantime, Uhas is planning more practical science collaborations for 2020.
- Uhas described the jaw-dropping foam volcano as environmentally friendly and said the team recycled the plastic wrap it laid down afterward. Dobrik’s house, however, is still stained.

Surprisingly, the neighbors didn’t seem to notice when the science YouTuber Nick Uhas exploded a massive blue-foam volcano in David Dobrik’s backyard.
“Every time I pull into David’s house, I swear by happenstance the neighbor is pulling out and is always waving and smiling, so I feel like we’re off to a good start,” Uhas told Insider. “The thing that I was actually most surprised about is we did not get a phone call.”
The world record-breaking elephant-toothpaste experiment that Uhas uploaded on Thursday has millions of views across platforms, but it hasn’t elicited a response from either the neighborhood or the pair’s competition – yet.
Uhas and Dobrik first tried the experiment earlier this year, and the resulting TikTok took off, becoming the most viral clip on the short video-sharing platform of 2019. It was an attempt to dethrone the YouTuber Mark Rober, who filled a swimming pool with multicolored foam earlier this year.
But there was some contention over whether the pair’s red-foam attempt actually produced more cubic meters of foam than Rober’s. So Uhas and Dobrik redid the stunt with three times the ingredients, and the resulting mass of foam spilled over Dobrik’s backyard balcony and rose above the roof of his California home.
“We’re kind of hoping it turns into a little bit of a foam arms race but we don’t know, nothing has happened so far,” Uhas, who has performed the experiment hundreds of times in his career, said.
Some viewers wondered whether the experiment was wasteful, so Uhas clarified that it was environmentally sound
The video ends with Uhas and Dobrik celebrating their gargantuan foam payoff. But how did they clean it up? Well, Uhas told Insider the reaction was “self-cleaning.”
“The foam bubbles start to pop, and what happens is the oxygen is released back into the air,” he said. “You end up with soapy water that’s on the plastic wrap. They get towels, they sop up the soapy water that has the potassium iodide in it, that gets washed – and that’s all drain safe – and then we recycle the plastic.”
The only thing that’s difficult to clean up? The blueish-green color that covered Dobrik’s white couch, along with the plaster on the outside of his house that the foam touched. The iodine that gets created in the chemical reaction makes for a pervasive stain, which Dobrik is well aware of, because it stained the ceiling inside his house.
“We did this inside once,” Uhas said. “They repainted it something like eight or nine times and it kept bleeding through the paint. What happens is the iodine just keeps seeping through the paint. That’s where I throw my hands up and go, ‘I don’t know dude, I’m the chemistry guy, not the paint guy.'”

Here’s a time lapse to show how we clean up the worlds largest elephant toothpaste experiment! The foam actually “cleans itself” by decomposing back into soapy water (with blue food coloring dye). We then recycle all the plastic and attempt to scrub out the color from David’s walls ???????????? – – – #science #sciences #scienceart #sciencefacts #edu #educational #education #stem #steam #chemistry #chem #chemicals #youtube #youtuber #video #videos #experiment #experiments #nickuhas #elephanttoothpaste #foam #worldrecord #record #blue #elephant #toothpaste #giant #reaction #largest #daviddobrik
Uhas uploaded a time-lapse video of the cleanup job to his Instagram page, but as far as he’s aware, Dobrik’s house still has a “minimal paint job” from the iodine stain.
Now that Uhas’ part in the experiment has concluded, he’s looking forward to his next projects. As the host of Netflix’s “Blown Away,” a glassblowing competition show, he’ll be filming season two early next year. He’s also gotten a lot of other YouTubers interested in practical science videos, and he says he has collaborations planned throughout 2020.
“I thought it would do well, but I didn’t think it would do this well,” Uhas said. “Some people were like, ‘This is CGI,’ and I was like, ‘Wow, we created something so impressive that people literally think it’s computer generated.’ That’s kind of awesome.”
