"A student left a camera on a picturesque mountaintop in Snowdonia in an experiment into human trust. Paul Bellis Jones, 24, left a note with the camera near the summit of Mount Tryfan, instructing walkers to take a picture then leave it for the next person. He was keen to know if the camera would be returned to his home in Glan Conwy, near Llandudno, as per his instructions, of if it would be stolen instead." - Anna Haro from Bookmarklet

"Thankfully for Mr Jones, over 30 ramblers took photographs of themselves at the beauty spot, which overlooks two large rocks near the summit. When the film ran out four days later, the camera was personally returned to his house by a National Park warden. The student, who left the camera and accompanying note in a sealed bag, launched the experiment in mid-May. He said: 'I was speaking to a friend who said you can't trust anyone, anywhere these days. 'I didn't want to believe that so I set up this experiment to found out what might happen and proved you can trust people.' - Anna Haro

Good thing it was in the UK. In the US, it's much more likely the camera would have been filched. - Spidra Webster
