Squirt gun install...
 

OK, while this could be just an opportunity to get you in trouble, I thought it was kind of funny. That said, I think it wold be cool if there was a little motor so you could target it? Seems like it would be relatively easy? I don't know who completely watches video this long? But it's easy to skip to all the relevant parts.

Seems like a roof-mounted, swiveling water gun could be super fun...
