Sebastian uses a power tool to unravel the string

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

Sebastian uses an angle grinder to cut through the reel of string, to remove it faster. Towards the end of his attempt, he switches to using a manual hand saw to remove the final few coils. He manages to remove all of the string in 49 seconds, earning second place.
