What new invention should I invent to make a lot of money?

I need your ideas. If you're too unmotivated to market your invention, or if you don't have as much money as I do to produce it, maybe you can tell me about it. I'll create it, market it, and sell it, and then I'll tell someone years down the road that you gave me the idea on this website. You don't get any money, but you'll get the thrill of knowing that your idea is making me a lot of money.
