# Rent-A-Rainbow

Ever wanted a rainbow?
 (+7) [vote for, against]

That's easy, for an reasonable payment of \$799.99 you can request a rainbow be made for that special outdoor event of yours. Wedding? Funeral? Barbecue? National Holiday? Simply tell us where you are, and when you want it; then we'll do the rest. We send a fleet of planes with several hundred liters of water to spray an extremely fine mist over a pre-calculated area.

With some guess-and-test, simple equations can be made that take in all the factors that determine the perfect rainbow. ie. sun angle, humidity, wind, place, time etc. Voila, rent-a-rainbow is born.

A work of art, but it does what you ask. [DrCurry]

 Pretty easy to calculate where a rainbow falls, directly opposite from the sun. And rather than a plane, a high pressure water fountain will do the trick. But do you always want to douse the bystanders in that direction with water?

Either way, croissant!

Alot like the link but a whole lot bigger, and the crowd won't get doused if its a few km away (like normal rainbows)

[swimr] but the crowd a few km away will.

where do you live that you can guarantee the sun? nice thought though.
 — po, May 04 2004

"Where ... the sun"?  Process of elimination, and it's not shining here.
 — dpsyplc, May 04 2004

Here, we have on average 330 days of sunshine per year. That's pretty close to a guarantee.

Must be nice...

Come on by. We'll turn on the sprinkler in the back yard and make rainbows.
 — half, May 04 2004

There's still a 9.65092402464066% chance it'll be cloudy when I get there.
 — yabba do yabba dabba, May 04 2004

Not if you get here today.
 — half, May 04 2004

 I spent an afternoon in a friend's back yard with some fine sprinklers and some very bright spotlights. No joy for night-rainbows. :(

 So the night rainbow had to be faked by projecting a rainbow slide onto the mist cloud. It looked OK, but nothing like a true rainbow.

 If only we'd had a plane and a sunny day...

I wish I could, half.
 — yabba do yabba dabba, May 05 2004

I'll take a large quarter-rainbow with mist. Hold the yellow.
 — k_sra, May 05 2004

would you like a side order of green with that?
 — swimr, May 05 2004

 For the rainbow-challenged areas, this would be a hit. [+] Eat hearty on this croissant.

[ydyd] Come to the Pacific northwest, there's a 9.65092402464066% chance it'll be sunny when you get here. ;)

I'm south of Seattle. We get the "Gorge Effect" here
 — Klaatu, May 06 2004

 Thanks, klaatu, but I'm kinda stuck at work right now. There's a 99.99999999999% chance I'll be the Denver area next weekend. Any bakers there?

is the .00000000001 % the possibility of winning the lottery ?
 — po, May 06 2004

Sounds more like the odds of finding a winning lottery ticket on the ground. Or of the planet being struck by a meteor. (runs off to do math)
 — Worldgineer, May 06 2004

That's when the meteor hits the plane.
 — FarmerJohn, May 06 2004

Looks like it's less likely than 1 to 1E11 that a meteor will strike [yabba]'s house (or, I assume, airplane), but it's more likely that he will become a saint.
