disclosing too much info to a stranger is not deviant. it's a general rule of common sense...which many break anyway, so ...nothing exceptional; i think it's a little risky because your teacher may disagree with your approach.
there are much simpler things you can do to break a norm, and which would generate tons of reactions. such as: pretend you are a beggar (dress accordingly), and people will probably tell you things. or, acts AS IF you were taking drugs, as if you were drunk - suppose you are age 16-18 so they'll be outraged. or better yet, have someone do this and you stay on the side and record reactions - it's more useful for you as observer.
some colleagues of mine got on a bus, dressed as bride&groom, with guests, singers etc
it's not deviant, but it was funny
