Janne uses strangers to distribute his clothing

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

Janne chooses driving as his initial mode of transportation, and drives into the city.

He then approaches strangers in the city and gives them his socks to take with them.

One takes a sock to her house, and another takes the sock onto the subway system with them.

Janne then places his trousers on a boat at the docks.

It is not disclosed what his fourth item was, or where it was placed, but the total area defined by the items is revealed to have been 1.13 square kilometres.
