Julie makes Mark do pretty much everything
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Julie asks Mark to get her a step ladder, then tape to cover the holes, then a jug of water, then asks him to pour the water into the tube. She does do the taping over of the holes herself, and pours in the last of the water to extract the ball after 3 minutes and 44 seconds, winning the task.
