Place it at the moment of the reveal, then follow with the shocked reaction before the laugh takes over and closes the joke. That order keeps the surprise first, the reaction second and the payoff last, so the edit builds instead of peaking too early.
关于此声音
This is a short popping sound effect lasting just over four seconds, built around a crisp pop that repeats and stretches out in a playful, exaggerated way. It feels light, silly and a little surprising, like a small burst going off at exactly the wrong moment, which makes it easy to use for a quick laugh or a sudden reaction.
