Stewart Henderson presents another sparkling series of Questions Questions - the programme which offers answers to those intriguing questions of everyday life, inspired by current events and popular culture.

Each programme is compiled directly from the well-informed and inquisitive Radio 4 audience, who bring their unrivalled collective brain to bear on these puzzlers every week.

In this week's programme Stewart helps a listener who has long been mystified as to why bacon comes in rashers but everything else in slices. He finds out why so many Greek theatres were built close to the coast and about a strange seaside phenomenon, the mechanical elephant. And, with Buster Keaton in mind, he discovers how fast a car would need to go to lift you off your feet and fly you horizontally behind it!

Producer: Kate Taylor

A Whistledown Production for BBC Radio 4.

Stewart Henderson continues another sparkling series of Questions Questions - the programme which offers answers to those intriguing questions of everyday life, inspired by current events and popular culture.

Now in its nineteenth series, QQ has become something of an institution on Radio 4 providing informed and ingenious answers to questions such as, How do you know when a volcano is extinct? When was the conventional heart icon first drawn? How do woodpeckers keep their beaks sharp? What is a Siamese Blood Chit?

Each programme is compiled directly from the well-informed and inquisitive Radio 4 audience, who bring their unrivalled collective brain to bear on these puzzlers every week.

In this richly informative programme all manner of questions are looked into.

Some recent enquiries that sparked particularly large responses included: What happened to all the wrought iron fencing that was collected during the Second World War? Is it possible to create one sound, which completely cancels out another sound? and How was the direction of writing originally established?

Among the array of puzzlers we'll be tackling during this series of Questions Questions:

- Why does the height of a swallows flight vary so much ?

- Can you hear a bell ring under water ?

- What is the origin of the word 'Wingwoms' ?
