Wallace & Gromit's World of Invention S01E04 - Come to Your Senses

Wallace and Gromit experience the world through the five senses, exploring the fact and fiction behind invisibility cloaks, bomb-detecting bees and the top sensory inventions.

In London, scientists are creating prototype invisibility cloaks using metamaterials to bend light around objects, and we discover the science behind new technology allowing the blind to 'see' through taste using hi-tech sunglasses.

In Kentucky, USA we visit the small town where a local farmer invented wireless telephones over 100 years ago. Or did he? Finally in Tasmania, we meet our Inventor of the Week who, after being told it was impossible, invented and made his own unique prosthetic arm.
