In this series, materials scientist Mark Miodownik charts the journey of human progress through the sticky substances that have shaped us.

In episode five he explores how the sticking power of modern glues – in everything from phones to furniture and planes to wind turbines – pose a problem, because they can’t be UNstuck.

He hears how modern electronic devices contain more glue than ever before, making them harder to repair and more likely to end up in landfill. But new designs could make our tech more sustainable.

And he learns about research into reversible glues that can be turned off at the flick of a switch, and how they could change the way we make, fix and recycle our stuff.
