Thanks nick!
So by soaking it with the shower heads, I'm not moving the heat away as efficiently as if I would use a light spray, which would take less time to evaporate and have more cooling affect.
The mist would also look neat imo b/c then i'd have a fog comming out of my scoop instead of streams of water and an occasional wind moved nozzle shooting streams at traffic. LOL I sprayed one lady in traffic and it went into her car. She wasn't looking and it got her, she look outside the window at the clouds with a confused look on her face!!! HAHAHA
