Jo completes the task with plastic cups
Jo starts out by adding a wooden platform to the scale (which only weighs 10.405kg), and then fetches a collection of bags (possibly belonging to the production crew) to add.
He removes the platform and piles on the bags, followed by a collection of other small objects, reaching a total weight of about 32kg.
He then adds some other items, bringing the total weight up to 37.820kg, far in excess of his target.
Checking the task brief again, he realises his mistake.
Having removed some of the weight, he then makes it back up to the target of 31.770kg using individual small plastic cups.
In the studio, Antoine reveals that Jo took 4 minutes and 1 second to complete the task, securing second place.
