Hello, I am currently working on a small project that involves an led inside a plastic ball. I'm using epoxy to make the plastic. The only thing is I want the led to be turned on by touching the outside of the ball. I was thinking maybe mixing in some metal powider with my epoxy when making the plastic, but i don't know if that will even work. Is there some sort of spray or paint able conductI've material I can line the outside of the ball with? Or is the metal powder my best bet?

make a capacitive touch sensor the TTP223 SOT23 IC is what you need
You need a piece of PCB or metal foil close to the surface basically make a small capacitor and when it is touched capacitance would change.
