On Sunday, August 23, 2026, the grand finale of Australia's National Science Week took a delightfully absurd turn at the Newcastle Museum in New South Wales. As part of the annual Hunter Science Festival, hundreds of curious families queued up not for standard lab demonstrations or rocket displays, but for an immersive trip inside a massive, walk-through intestinal attraction known as the HMRI Poo Palace.
Designed by researchers at the Hunter Medical Research Institute, the vibrant inflatable structure invites young visitors and adventurous adults to step directly into the mouth of the digestive tract and follow the exact path of food from "lips to lavatory." Along the squishy, cushioned passageway, participants encounter interactive exhibits explaining stomach acid, gut bacteria, nutrient absorption, and the biological mechanics of bowel movements.
Organizers noted that the Poo Palace has consistently proven to be the festival's most popular exhibit, leveraging humor and tactile fun to demystify complex gastrointestinal science. By turning body functions into an engaging bouncy-house-style adventure, scientists hope to spark early interest in biology and health sciences without any of the usual squeamishness.
