Calle takes a bike ride

Calle initially states that the 10 minutes of preparation time is "for idiots".

He then tests an elaborate system involving the cement mixer, a table, and a Norwegian flag, before seemingly breaking the mixer with just a minute and a half of preparation time left.

With Olli’s help, he then removes the seat from a bicycle, and places the reel of string onto the seat stem.

He secures the loose end of the string under a cinderblock, with Olli standing on top of it, and then cycles a lap around the house, before heading out into the street with 15 seconds remaining.

Calle ends up unravelling 176 metres of string, which earns him third place.
