Blue Peter Badge! Answered
It won't mean much (anything?) to non-UK readers, but #2 son's Instructable has earned him a Blue Peter Badge! On a whim, after he got so many favourable comments, I emailed Blue Peter and told them about it.
He got the badge in the post today (it's the blue one ), which probably means he was mentioned on the programme, and the site may have been as well (have we had a spike in young UK members?) (I've emailed BP to ask).
An absolute mystery to people outside the UK, but a major event in the life of any UK child.
