I would probably use a piece of string or fishing reel for extra stregth. it wouldn't move about because the string would be really tight. I'm not sure how to stop the black hole evaporating though...possibly a jet of water to keep it moist. I don't think it would suck in surrounding matter because of all the light we were 'feeding' it.

I am studying physics. A recent holiday found me in the lab with some laser equipment. Having been facinated with Star Wars from a young age I set about wondering how to make a lightsaber. The problem is not in the laser beam, but how to stop it at a certain point. One possibility was a mirror on a piece of wire that would be projected under the power of the light photons to the projected length of the retainer. The other possibilty would be using the same concept, but merely tethering a small black hole to the end to absorb the laser. What problems could this cause? Could it be done? Sorry if this is the wrong thread, but would love some input.
