If I were to tell you that you can get a complete, worldwide patent search conducted on your invention idea for $9.99, you would think I just swallowed a whole lot of advertising bull. I thought it was too good to be true too, so I went to the source, the company that owns and offers the ideaAPP for Apple and PC products, and asked the founder an irritating amount of questions. He answered.
O-rings. They're those small, looped elastomers that mechanics and photography hobbyists always seem to say they need when they're in the middle of some project. I was pretty much blown away by how useful these little buggers were, which led me to think about what the world would be like without o-rings--and let me just say, it wasn't pretty.
