Young Stratford theatre-goers enjoy grotto magic

If you take your family along to a performance at the Discover Centre in Stratford this Christmas you will not be allowed to just sit and watch.

The Punchdrunk theatre group's show takes place in a magical snowy grotto and the children in the audience are invited to get up and take part.

BBC London's Wendy Hurrell talks to some of the children in the audience to get their reviews of The House Where Winter Lives.
