For thousands of years people thought we had 5 senses, now it's believed we have up to 33. In this ten-part series, philosopher Barry Smith and sound artist Nick Ryan take us on a journey into the extraordinary world of sensory perception.

In this episode we introduce the most multisensory experience on earth: Dinnertime!

Food keeps us alive, it makes us happy, it powers everything we do. So it should be no surprise that many of our senses are geared towards helping us find a good meal. With guest Heston Blumenthal, Philosopher Barry Smith delves into all the ways our senses are enhancing or changing the experience of eating, in some very unexpected ways.
