'It's like a secret language': School that teaches in Manx

In 2009 the Isle of Man's native Manx language was declared "officially extinct" by Unesco.
But the pupils at primary school Bunscoill Ghaelgagh in St John's are proof that the language is alive and well - at least for them, if not for their parents.
It is the only school in the world where children are taught in Manx.
