Hidden Voids and Silent Doors: Our Weekly Picks

Why these picks

I’ve spent years looking for things that aren't on the map. It's funny how much we miss when we just look at the surface. This week, our partners are looking at what’s happening in the dark spaces under our feet or behind the scenes.

One story looks at the actual holes hiding under our roads. Another talks about maps for water you can't even see. I even threw in a piece about how things can move without making a sound. It’s all about finding what's hidden. Ever wonder what's right under your boots?

The Art of the Silent Move

Secret doors are cool, but they aren't very secret if they squeak. This story is about making machines move with air so quietly you wouldn't even know they're there. It’s a bit techy, but it’s the kind of stuff that makes hidden rooms work. Plus, it’s just neat to see how artists make things move like magic. Source: diynewsmagazine.com
