Today I uploaded a second video about a student project at the University of Nottingham.
Three engineering students were tasked with building a roof rack which could be used by one person using a tandem bicycle.
I should emphasise it is a "student project" as part of their degree - they're not taking this to market. It was filmed for Test Tube.
Here's the latest video, in which the rack is tested on a crash track.
And here is the previous video when the rack was first fitted to a car.
