Ekspolsiv trappevask (explosive stair)

Ikke gjør dette hjemme

With a name like that - loosely translated as "Don't Try This At Home" or "Never Do This At Home" - a show is allowed to take a few liberties.

In this clip, the hosts have found a creative way to clean the stairwell quickly. They combine hydrogen peroxide (assumedly 30%) with potassium iodide (a catalyst promoting the quick decomposition into water and oxygen gas) in a soapy solution. To that they add a bit of (as seen in the original video - skip to about 24:25) n-heptane (though the translated captions call it 'gasoline') making for an explosive, highly theoretical dry finish to the 'clean-up.'

I'm thinking that the process goes about as well as they had expected it to.

For bonuses, I'll embed a video of the same folks showing how quickly an improperly-handled grease fire can get out of hand.
