Chapter Nineteen through Chapter Twenty

In chapter nineteen through chapter twenty, Griffin describes what has happened to him since the last time the two met. Griffin got a fancy for light and physics, so he decided to study it in earnest. He made several huge discoveries, but he never published them because he wanted to keep them a secret. He thought that the only thing that managed to make people visible was the amount of surfaces to reflect the night. For example, glass is transparent because there are not many surfaces to reflect light. However, if you powder it and make more surfaces to reflect light, it will become invisible. But if you put it in water, it will again become invisible because the water has the same type of reflection as powdered glass does. He put this theory to work and soon made an invisible cat. He decided also to make himself invisible because he thouhgt it would benefit him in life.
