Inês retrieves the table tennis ball
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Inês pours half of a bottle of the provided liquid into the tube before she realises that the tube has holes in it. Inês wonders aloud how to get the table tennis ball out of the tube, before coming up with the idea that she’s meant to use a straw to suck the ball up the tube, using the holes in the tube to help position the straw. If she actually tries that idea, it is not shown. Inês finally realises that she just needs to cover up the holes, and uses her fingers to cover them up while pouring liquid into the tube. When the ball is halfway up the tube, she blocks it with a straw and shoves cloth into the bottom holes so she can use her fingers to plug the top holes, and finally successfully removes the table tennis ball by causing the pipe to overflow. Inês takes 12 minutes 45 seconds and earns last place.
