I'm recreating a prop and I'd love for one of the pieces to be a translucent green when I'm through with it. For reference, it's the emitter bulb at the end of the Sonic Screwdriver from Doctor Who: Notice the marble swirls and translucent look to it. One thing I'd love to do is incorporate an LED into this prop, inside the bulb, and from seeing FD and FUD in regular lighting, it seems quite translucent already with thinner walls, so making this piece hollow would make it relatively see-through. My question is, has any one had any success dying this material? And if so, does it appear translucent afterwards? I figure if I can find a dye that works, I can water it down to varying degrees to get the swirl effect and then insert a green LED to complete the look.
