Roni unravels the thread by foot
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Roni attaches one end of the thread to the flag pole in the front yard and then holds the spool in his hand and runs away from the pole.
He unwinds 177 metres of thread from the spool.
