It's the classic "guess my age" trick. I stripped this effect down as best I could. It uses their phone, requires no apps, they do all the work, so you can focus on your presentation and reveal. It's one of those effects, that's basically impromptu, ready to perform when you are, with minimal prep. I broke it down to it's core, included the slightly extended version, and some additional suggestions.
