Jenni unravels a thread from a window
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jenni unrolls the thread on the stairs, but it quickly becomes tangled, slowing her attempt down.
She then abandons this method and starts instead unrolling the thread from a second story window.
Jenni unrolls 160 metres of thread from her spool.
