A glass tube is enclosed inside a black paper box. The glass tube has wiring in it that runs inside-like a light bulb. Now the electrical currents can build up inside the glass tube. An electrical apparatus can now travel into the tube because it was connected with an induation coil apparatus. A faint green light showed up across the room. Lighting a match will help appear a small screen across the room that has chemical coated on it. Blow out the match and the same light appeares. This became known as the first x-ray picture.
