This was the "electric fence" challenge. Simply put, the group had to get everyone from one side to the other without "electrocuting" themselves. Easy enough, you might think, but they also had to hold hands for the entire process. If anyone let go, or got zapped, the whole activity had to begin again. They got there eventually, but there was some head scratching along the way!
As you can just about see, the solution involved two lucky volunteers acting as "steps" which allowed the rest of the group to gain the necessary altitude to clear the deadly fence (I know it looks like a rope but use your imagination, folks!).
The fence was by no means the only cunning challenge our intrepid team had to face. A real stumper was the simple test of walking in a line from point "A" to point "B". The only rule was that the group's feet had to be touching for the entire journey. As you will see below, this is really quite tricky but Tia came up with a different approach in the end. Not dignified, I'll admit, but it worked!
