What we did
We thought to ourselves, when are students most likely to want to escape the UK? Probably right after one of their exams. And what symbolises escape? Probably a free ticket out of here.
So we printed thousands of 'boarding passes' - that is, a flyer, that looks an awful lot like a free ticket to Oz.
One of these tickets was real. Students were told to go online - and enter their details - to find out if their ticket was the real one.
