Pranks with pens you can do include the old-school classic of whistling by blowing through the pen, writing on the wall using a pen that contains a special ink that only appears when exposed to ultraviolet light, making a homemade Ouija board with a pen and a piece of paper, writing on someone's mirror when they least expect it using a shiny pen, and drawing designs on a paper napkin with the cap of a pen.
