ELI5: why do only some materials work on touchscreen, and what is in touchscreen gloves that makes them work?

The basic difference is conductivity + surface area. A needle will not work because it has very little surface area that can directly touch. A cotton glove will not work because it is not conductive. A glove with a bunch of flexible little conductive fibers WILL work.
