That was really very good - the mural finishes up very well.
The comments of the children showed a keen interest - I had to chuckle when the boy near the end starts to talk cosmological and context was quickly switched back to the mural.
The UNAWE website is impressive - even covering making a reflecting telescope out of cardboard tube and shaving mirror. However I'm a bit wary of the sugestion that kids focus an image of the sun onto a wall to determine focal length.
There is a lot of good material there to aid teachers present astronomy and space to children and to enthuse them - I enjoyed my brief visit.
