Siri hopes for an explosion

Siri drops the reel of string into a cement mixer, and also pours in a large quantity of various flammable liquids from the garage.

She then drops in a pair of matches and, while this does ignite a fairly aggressive fire, it doesn't create the explosion she was hoping for.

After Siri's time is up, Olli puts the fire out with a fire extinguisher, covering himself with powder in the process.

Despite all the flames, the reel appears largely untouched at the end of the task, since the fire had been consuming all of the fuel she'd added, rather than the string itself, which had merely been acting as a wick.

Having removed zero metres of string, Siri finishes in a clear last place.
