Is it possible to create indoor rain?

Question

would boiling heaps of water in a room, then imitating atmospheric systems on a small scale create indoor rain?

Answer 1

Yes.  In fact, you can even do it in a small container like a bottle.

Answer 2

Yes actually, if there is any amount of water that is evaporated that contacts cold air, it can come down again as rain. Many science classes do this experiment with a heat lamp, an ice pack, some water and a small inclosed area with high and low areas.

Answer 3

Yes, I've heard that the huge Vehicle Assembly Building at Cape Canaveral, where spacecraft are assembled before launch, requires special air conditioning because otherwise it would rain inside the building.  It's large inside volume and moisture from all the people at work allows a self contained weather system to form as the warm moist air rises and cools and the moisture condenses out.

Answer 4

As Suki Dee has stated VAB at Cape Kennedy (Canaveral) is the world's largest single storied building, a cube of fifteen floors on the side. When no rocket is inside it, it is a good idea to do experiments with indoor-rain-making. One can replicate it, scale down to ordinary room size.
