This short video is an update from our current Mould Experiment Scientists Leigh and Keegan from Room 8. As regular followers of this site will be aware on February of this year the students from this class created a series of sandwhiches with various ingredients and then sealed them in plastic bags. That was two monts and four days ago. Today the scientists update you on the progress. They are joined for this by Tim from Room 17 who happened to be in the room when we filmed the presentation.
