The players were led to a wall of holes with water gushing out, surrounded by piles of pipes in various sizes.
"To win your dollars, change the flow, by using all the facts you know," their instructions read. "Questions from your jungle lives answered right will win the prize."
Adam and Sam realised they had to solve the numerical teasers on the wall, and use the pipes labelled with the correct answers to fix the leaks.
However, it was easier said than done. Adam said: "The questions were so difficult, we were way off the mark."
Sam added: "I thought we communicated really well, but I'm not gonna lie, we were raging at one point."
After getting thoroughly soaked, the pair finally got the Dingo Dollars, spending them on corn chips and salsa.
Kiosk Keith gave the other celebs a quick call to ask: “What percentage of UK adults admitted to having their heart broken - 61% or 77%?”
Believing that most people will have experienced heartbreak, they settled on the higher option. Scarlett Moffatt commented: "It’s got to be the highest one, I mean, who hasn’t had their heart broken?
"Even if it’s just going to order a kebab and realising the kebab shop is shut!"
It turned out to be the wrong answer, meaning Adam and Sam had to return to camp empty handed.
However, more treats were up for grabs shortly afterwards when the campmates faced another challenge live on ITV’s This Morning.
