I thought I'd let you know about a product that might be the next step up from the Room Defender you posted about. The Scarecrow is a motion-activated sprinkler. It's made as an animal deterrent but I expect it would work just as well in your bathroom or next to the front door with the convenient mounting bracket to keep away meddlers. On the web site they got some video of it being used on some poor dears, dogs and birds. I don’t know why they aren’t marketing this as a toy as well.
Link (don't miss the videos!) - Thanks Cliff!
