Winter bugs: Hand sanitisers

With offices and schools set to a soundtrack of sniffles, science presenter and YouTuber Greg Foot is on mission to find 'The Best Thing Since Sliced Bread' to beat the winter bugs.

Joining him for this double episode is rapper, podcaster and actor Scroobius Pip, a man for whom protecting his voice is a professional priority. Under the microscope today are those handy hand sanitisers that promise to stop bacteria and viruses in their tracks.

Virologist Wendy Barclay from Imperial College London and microbiologist Lindsay Hall from the Quadram Institute in Norwich are both on hand to help separate the facts from the fads, to decide if these products really are The Best Thing Since Sliced Bread.
