I have attempted to complete a project where the participants do not know they are participating. I have placed a piece of tranferable graphite paper underneath my friend's notbook pages while they were taking class notes and collected them from different people. This created a mess of different handwritten notes and ideas from different student's classes. It took me a very long time to accomplish this becasue not only did I have to sneak the graphite peper under their notebooks, but I also had to retrieve them without the participants noticing. I cut out only small squares of the graphite paper so that it would stay hidden behind their actually page to keep the secret intact and also to semi-control where there notes would be taken. Because the paper is transferable, anything writen on the page above would be tranferred to my placed page underneath. Another interesting effect I got form this is that since the notes are being transfered, all of the words came out backwards!
