I can finger whistle!

I feel like a child. 🤣 I've wanted to do this all my life and, along with a couple of my kids, we decided to look up tutorials and make it happen. And... I can finger whistle now! And I can't stooop! 😗🎶

There's multiple ways to do it and they're all pretty similar, but the keys seem to be rolling back the tip of the tongue and making sure to close off extra spaces so the air has only one route to travel.

What's something silly you've learned recently that's brought you joy?
