Quote: Ames' original design also contained a groove that was positioned such that a ball in it appears to roll uphill, against gravity. Richard Gregory regards this apparent "anti-gravity" effect as more amazing than the apparent size changes, although today it is often not shown when an Ames room is exhibited. He speculates that "magnetic" hills or "gravity" hills can be explained by this principle. For a magic mountain at an unnamed location in Scotland, he found that row of trees form a background similar to the setting of an Ames room, making the water in a creek appear to flow uphill.[1] For Gregory, this observation raises particularly interesting questions about how different principles for understanding the world compete in our perception. The "anti-gravity effect" is a much stronger paradox than the "size change" effect, because it seems to negate the law of gravity which is a very fundamental feature of the world. It seems counterintuitive that the expectation "rooms are rectangular" can override such a fundamental experience. In contrast, the apparent size change is not such a strong paradox, as we do have the experience that objects can change size to a certain degree (for example, people and animals can become smaller or larger by crouching or stretching).
