Fun Phantasy project "bad conscience"

Hi, this is a fun project, where you have to use your power of imagination. The payment is fix, please just bid 30$. The question is, how could an object or product look like that is able to clean/lighten/solve a bad conscience? Or in other words: How could something look like that can rehabilitate a good conscience? Its just an imaginary work, but I would love to see a designed object/product which can do that, so you can make a productdesign or logo or icon or concept design. It`s up to you. There is no right or wrong. If you want your bid to be concidered you HAVE to send a mockup first with some detailed informations about your imaginary product. Happy creativity! Cheers
