Quicksilver Matches

It's Magic 101. Can you mimic the master?

Effect: Taking two matches from different matchbooks (one black, one brown), you cause them to visibly switch places...right under their eyes. It's demonic; it's the Quicksilver Matches.

Method: Both matches have one light side, and one dark side (kind of like jedis). Two matchbooks are prepared so that one shows the dark side, and the other shows the light side. Remove a match from both books keeping the different sides facing up. Hold the matches by the head, and when you turn the matches over to show the backs, roll your thumb to flip the matches over. Essentially, you're showing the same side twice, but it looks like both sides are being shown. After showing "both" sides, quickly execute this "pop move" to turn both matches over, showing each match's opposite color. It looks exactly like the matches have instantly changed places
