I have an idea for an invention, and I’m willing to give up my intellectual property rights to anyone willing to develop it and market it. Here’s how it works. Imagine that someone, for example, a child, has just finished using the bathroom. My invention is attached to the toilet, and when the child stands up, a weight sensor will trigger a timer that will allow five seconds for the toilet to be flushed. If it has not been flushed by then, my invention emits a horrible piercing shrieking sound which continues until the toilet is flushed.
Simple, easy, effective. And, like I said, totally up for grabs — as long as you let me purchase the first three manufactured.
