In the UK we have some sticky stuff used to hang up pictures etc, we call it ‘blu-tak’, it’s usually blue.

We got some here, different name but we still call it Blu-tak. Except Max, who has mis-heard.

‘Daddy, where’s the Blue Tang, I want to stick up a picture?!’

I guess only a kid who’s been snorkeling tropical reefs would come up with that one.
