A Blue Peter presenter will be revealing the inside of his stomach live on the famous children's TV show by swallowing a pill.
Radzi Chinyanganya will be undergoing a capsule endoscopy on the long-running series, once famous for making anything and everything out of sticky-backed plastic.
The technology uses a pill to capture live video footage of the gut through a tiny camera.
Chinyanganya will swallow the capsule cam one hour before the CBBC show goes live tomorrow, so that viewers can watch the pill's journey through his body.
He said: " This is the first time we'll see inside any of the Blue Peter presenters' internal organs. I just hope I can stomach what I see..."
Specialist Dr Adam Haycock will use the footage to give a lesson on digestion for the show, which is broadcast every Thursday at 5pm.
Broadcaster Michael Mosley previously swallowed a tiny camera transmitting live pictures of his body digesting food for a BBC4 documentary.
