Inventing something original.. not invented yet?

Question

okay. I need to invent something original and be able to convince people that it will make them money if they can mass produce it and sell

and of you like these how can i go about advertising them like what would i say?

fountain of youth

or

a tv that lets you change the channel by calling out the number

Answer 1

the fountain of youth is good. everybody wants to be younger and live for a longer period of time but with botox and cosmetic surgery around, i think that is already covered. you could try innovating something. your tv idea is really good. people lazy enough to press the buttons on the remote would love it.
