I'm in the USA and have about $50K, that I want to put to work.

I'm hoping some of the experienced, successful guys will suggest a hands-on idea, that perhaps includes buying a machine, a tool, a vehicle, or something in that price range, that I can work to make a better return on investment than could be gained from a hands-off, passive investment like stock, bonds, etc.?

Maybe there something else that I haven't thought of? Thanks in advance.
