Test Tube's Brady Haran was a guest speaker at a special event in Northampton.

He was speaking at the STEM Student Journalist Media Workshop at Britannia House, with about 95 students and teachers in attendance.

Brady shared a few tips and stories about making science films - and showed a few video clips from Test Tube of course.
