How to make a fake thunderstorm outside your window?

Question

you're walking into the haunted mansion at disneyland and you go through the elevator. when you come out of the elevator you're in a corridor with portraits on one side and a couple windows on the left. outside there seems to be a huge thunderstorm going on outside.

i wanted to make something like this for one of the windows in my room. does anyone know how they get that effect? i dont want to use any water, just lights and sound. any ideas?

Answer 1

use a sprinkler on the end of a hose fixed to the up stars window, get a flexible sheet of steel, then get someone to go outside and flex the sheet of steel and turn the hose on at the same time, you could even get some one to turn a flash light on and off for more of an effect.

Answer 2

Sprinkler head and a bad recording of Hanson?????
