On Saturday 23rd October, over 300 visitors enjoyed an array of fun and hands-on activities at the annual Family Fun Day at Great Ormond St Hospital. INTENS consortium organised activities explaining how to create organs in the lab, skilfully led by the researchers themselves, opening up the opportunity for dialogue about the work of the consortium and being a scientist. Among the different activities the visitors enjoyed, there were a virtual reality tool allowing ‘to see the organs inside their body’, microscopes, a chance to make their own mini-intestine from stem cells using craft materials, and a breath-taking mock-up of a bio-reactor used to grow organs in the lab.
