Emilia, Nathan find chili in the jam
The prank was chosen by viewers when they were asked to vote for one of three potential practical jokes.
The circus performer tried to open the jar as she prepared her breakfast, but when she found it too difficult she asked Nathan to help her.
"I'm not stupid, they've put something in it," Emilia said as Nathan opened the jam and smelt what was inside.
Amy announced: "They've put chili powder in the jam!" An unimpressed Anthony complained: "How old are you? Grow up guys, yeah funny, well done."
