8. Mark It on Tickets

The colorful plastic and paper wristbands used at concerts, festivals, and other big events can be customized to show a designated hashtag. To encourage guests at its Party in the Garden fund-raiser to upload photos via Instagram, the Museum of Modern Art in New York handed out entry bracelets printed with the hashtag #PitG2012.
