Is it possible to rain indoors?

Hangar One at Moffett Federal Airfield in Mountain View, CA. Built in 1930 to house military dirigibles.

It has been a skeleton for 12 years or so (it was stripped down, after asbestos was discovered), but back in the day, thunder storms can form inside. They were planning on restoring as a historical site.

Sure. I remember when I was a kid we made ‘rain in a bottle’ science projects

Yes... That's how I found out that the boiler in the property upstairs had blown.

Yes. That's when you call a roofer.

It could be raining inside the Tennessee aquarium it’s a big building and there’s a tall nasa building that has rumors that it rains in the building on very humid cool days. Moisture can condensate and become foggy clouds and fall down as precipitation.

Darn tooting!

I think they call it sprinklers.

{@laffytaffy] 😆 yes if you have a hole in your roof

I suppose if your roof is leaking.
