Operation Ouch! Food, Poo and You

Dive headfirst into the digestive system for an unforgettable journey of super-sized science with Operation Ouch! Food, Poo and You.

Get ready for a special mission to find out what happens to food when we eat. 

Guided by videos and illustrations of our hosts Dr Chris, Dr Xand and Dr Ronx, prepare to be shrunk, swallowed and squeezed through Dr Xand's digestive system.

From the tip of the tongue to the end of the bum, explore the role of each organ in the digestive journey through interactive games and challenges, fun facts and fascinating objects from the Science Museum Group's collection.



  • Enter the mouth and play in a set of giant teeth to find out why our teeth are different shapes. 
  • Bop the bad bacteria as quickly as you can in the stomach.
