The four of you are now in a room with a giant scale. It seems that the giant has left his lair for now and the scale is free to use. However, it is a very tricky scale. But first, I shall describe the win conditions for this task.
The team members must guess which player is the heaviest. Well of course, I wouldn't ask people their actual mass/weight, so you all have been assigned hypothetical values. The team will get ONE guess, and that is it.
Before you make this guess, you are allowed to step onto the scale on either side A or side B. Once players are set, the scale will tell you which side is heavier. The catch, however, is that only one player must not be on the scale at any time. The other catch, however, is that if a player is on the heavier side twice, on the second time, this player will fall off the scale and can't get back on the scale for the remainder of the challenge.
To step on the scale, just announce that you will step onto side A or B. When you are in place the player off the scale must announce that the scale should start balancing. At that point, the scale will show that either side A or B is heavier.
