Sure thing. First, pick a point where the opponent’s attention will naturally dip—maybe after they announce a move, while they’re checking their clock. That’s when you’ll switch a pair of pieces; make the swap look like a normal reshuffle, so no suspicion. While they’re distracted, flick the board lights a single second. The brief blackout will give you a second to trigger the confetti timer. Keep the timing tight—exactly 3.5 seconds between the flick and the pop—so the confetti explodes right as they notice the board reset. It’s a clean, controlled chaos.
