Place it just after the reveal in your edit, once the surprise is clear, then follow it with Oh My God Wow to escalate the response and finish with Kids Cheering if the moment turns into a win.
關於此聲音
This is an 11-second vocal clip centred on one long, drawn-out ouu, delivered in a rising, expressive tone that stretches the sound out rather than snapping it short. It feels surprised and impressed at once, like a playful gasp you make when something unexpected lands, turns awkward, or suddenly looks better than you thought.
