Gilmário empties the bathtub
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Gilmário decides to siphon the water from the tub, and puts Nuno to work holding the other end of the hose in the tub while the water drains. Gilmário uses a helmet to help empty the tub while the siphon continues its work. To get the last dregs of water, Gilmário uses what appears to be a tangled mass of cloth ropes from the shed. Gilmário empties the tub in 6 minutes 10 seconds and earns second place.
