Mehdi sucks on a tube

Mehdi identifies that the flexible tube attached to the foot pump can be removed.

However, instead of using it as a siphon to efficiently move all of the water from one bowl to the other, he repeatedly sucks water up into it, and then releases that water into the second bowl.

In total, he transfers 3,044ml of water, which earns him second place (despite the fact that Matthieu, who would have earned first place, received a deduction of 5 points).
