Mahamad builds a potato tower

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

Mahamad spends the majority of his time carefully stacking slices of potato on top of each other. However, when Annika quickly steps away at the end of the building time, it (at least, according to Mahamad) creates enough vibration on that part of the floor that his tower falls over. Mahamad earns last place.
