OK, I'd seen this thing working last summer at a kiddie pool in Alamo Ranch. Yesterday, I took a photo. These things work by filling up a cone, and then when the cone gets top-heavy, it dumps the contents. This could be relatively easy to make in acrylic, with a "V" shaped box. It can't cost more than a few dollars and a cheap pump. Maybe even a giant funnel?
