Banana, water and human touchpads

Two students at the Massachusetts Institute of Technology (MIT) have developed a banana piano.

Jay Silver and Eric Rosenbaum were looking for a way of turning everyday objects into touchpads.

They have developed a kit that can turn fruit, animals and even humans into keyboards.

Mr Rosenbaum told the BBC the idea was to enable people to "see the world around them as a construction kit".
