Like Orson Welles did in the 30s here! Scared the poop out of a lot of people with an excellent presentation.
My daughters were quite young at the time 9 and 11, we let them stay up to watch it because there were a lot of kids TV presenters in it and they had been pluging it during childrens TV. At no point did they hint that it was going to be a scam. They went to bed shitting them selves. It was a great bit of TV.
