Kiell's balloon basket
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Kiell orders a "ball for golf", a balloon, a basket, a blue hat, and some bacon. He accidentally bursts his single balloon during construction, but Alex is able to replace it for him. He attaches the inflated balloon to the basket, where he says the egg will travel, wearing the small blue hat. While he is describing his plan, he realises that water is going to seep into the basket, and asks Alex the question "How heavy is the water?" (thus coining the title of the episode). Kiell's balloon has deflated considerably by the day of the boat race itself, but it remains afloat, and crosses the finishing line second, after 1 minute and 45 seconds. However, after Frankie is disqualified, Kiell moves up into first place.
