The quirky exhibit is among a host of activities the public can get involved in during an event designed to let people see behind the scenes of one of the busiest hospitals in the country.

Discovering how dance helps the elderly recover from illness, getting your teddy bear’s health checked and trying your hand in a mock surgery are also on the list of not your usual Sunday activities.

The milestone open day is on Sunday March 20 from 11-4pm.

Staff achievement, patient care, research and teaching are all being marked.

Addenbooke’s Hospital was officially opened in 1766 and the day is designed to let people explore the story of the hospital’s past, present and future.

Staff will be on hand to share their knowledge and experience.

Visitors can browse the archives at the people and events that have made the hospital what it is today and can also look to the future with the development of the Cambridge Biomedical Campus and the future for science, research and innovation.

Among the talks, activities, and displays are lectures on 3D neurosurgery, biomedical research, the history of the hospital, learning how to take blood, getting to grips with being a neurosurgeon, finding out how medicines work and learning about infection control.
