If you grew up in the ’90s then chances are at some point you’ve wondered what exactly Nickelodeon’s infamous green slime was made of.

Or even spent summers trying to recreate it for yourself – well now we have the answers.

In an interview with Tech Insider the man closest to the secret recipe, Nickelodeon game show host Marc Summers revealed the original recipe for iconic green slime – a secret that has been kept under wraps for many years.

“You know, it’s weird. Slime is hot again,” Summers says. “And there’s all these recipes online that have nothing to do with what we used as real slime. It started off with vanilla pudding, apple sauce, green food coloring and a little oatmeal.”

So while it looks radioactive, it’s actually pretty safe to eat.

The prank started back in 1979 with a Canadian show called You Can’t Do That On Television and if the contestants said “I don’t know” at any point they would be doused in the luminous substance.

It then became more mainstream when Summers presented Double Dare but more recently it’s famous for covering some of the biggest celebrities at shows like the Nickelodeon Kid’s Choice Awards – where the likes of Katy Perry, Justin Bieber and Will Smith have all been slimed.

However Summers then went on to shame the slime imposters of 2017: “The consistency of that was far better than the stuff that I see today. I don’t know what it is.”

Today’s slime seems much runnier and much brighter, making it all the better to cover celebs in.

The TV host explained that he got away with 65 episodes of not being slimed on the show however that all changed towards the end.

“So the next thing I know, all the kids are trying to trash me with either slime or pies,” he says. “And, you know, some days I’d look like a Smurf. I’d be head to toe with blue whipped cream, blue kind of icing, whatever was on the course.”

But he admits that it was all in good fun!
