Mehdi heats his knife blade
Mehdi initially comes out of the shed carrying a blunt trowel.
He then thinks better of this, and runs into the house, returning with a craft knife and a gas stove lighter.
Inside the shed, he heats the blade of the knife with the lighter.
Then, for some reason carrying a wooden hand-shaker percussion instrument in his free hand, he quickly stabs all of the balloons with the hot knife, completing the task in just 15 seconds, and earning first place.
