The Japanese museum that really rocks!

There's a rather unusual museum in Japan, called Chinsekikan - which is full of strange rocks.

Funny faces, scary faces, famous faces....even faces resembling our Outlook presenters. Our reporter Alessia Cerantola has been to find out more. (Picture credit: Alessia Cerantola.)
