The Case of the Invisible Text
PowerPoint slide transitions are best left to the fourth-grade science fair crowd. But if you insist on using them (don’t say we didn’t warn you), make sure that your text doesn’t behave like a Cheshire cat.

, the slides leading up to this one (slide 18) are visually interesting and don’t overdo the text or graphs. But slide 18 contains three bullet-type points that appear and then disappear as the presenter clicks through it. The only thing worse than putting multiple paragraphs of text into a slide is putting up text that vanishes unexpectedly. It’s supposed to be a visual aid, not a magic show.
