Jenni uses a hose to make the sauna stones hiss
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jenni brings a hose up to the second story window and squirts the stove from there.
The distance is measured at 10 metres and 60 centimetres.
