I love the idea of this "Mystery box". The mathematics here is pretty abstract but it doesn't matter because the context of the mystery is what draws them in. You can try it here but @DDMeyer also takes you through how to create your own with this single slide @Desmos activity. And then he drops the challenge for you to make your own version and share itl

I think the process of doubling (or halving) is one of those skills that can be so useful for students.

This is not the first time I have shared this resource (and I will probably share it again) but I really love it and think it's good to get a reminder of it. It's an article titled "Never say anything a kid could say" and it basically about the different ways that you can stop telling stuff in your class and move to a classroom environment where kids do all the telling. It's a great read. Thanks to @RobertKaplinski for sharing this again.

So I don't know if you need to watch this whole video but the part that pertains to math is kinda neat. Though he doesn't say why this works. I think that you could use it as a way to show a specific practical connection to trig. You could start at 530 ish to get right to the math part.
