'Floor Is Lava' Creators Explain Why They Won't Reveal How They Make the Lava

Floor Is Lava is one of the latest sensations on Netflix and people are loving the competition series!

The show was filmed a whole year ago in the empty IKEA building in Burbank, Calif. because no studios wanted to have the lava inside their buildings.

“We asked all of the main studios and nobody wanted 100,000 gallons of lava on their stuff, which is understandable. Even the places with giant pools that typically hold water, lava is heavier than water so they didn’t want that in their pools either. So we ended up lucking out and we found this IKEA and it was huge,” series co-creator Megan McGrath told THR.

When asked what the lava is made of, the creators wouldn’t say. “It’s a proprietary blend,” McGrath said. Series co-creator Irad Eyal added, “It’s literally our secret sauce.”

“We tasked Hollywood’s biggest chemists and slime/goopy substance-makers to come up with our lava. We did a ton of research about what lava looks like and how it moves and how it glows and we tried to really create that in ours. We spent months testing different lavas and different formulas,” McGrath said.

Eyal said, “The reason we’re being so secretive about it is because it really did take a long time to nail this down. You want the lava to glow. ‘Oh, that’s easy,’ the chemists said, ‘we could just add in some glowing chemicals.’ Well, it turns out those things are carcinogenic. So you can’t have that in there. So it took a long time to figure out exactly how do you make this thing bubble, flow, be slippery, be viscous in the right way, and also be safe that people can be submerged in it for minutes at a time, hours at a time, whatever it is, and come out safely.”
