Research has shown that presenting a food portion in a smaller bowl creates the illusion of a larger portion. Conversely, presenting the foot in a larger bowl creates the illusion of a smaller portion. The quantity of the food remains the same. This phenomenon is known as the Delboeuf illusion. This illusion forces your mind […]
It certainly does not appear to be true, but the two monsters shown in this illustration are identical in size. It looks like the monster in the background is significantly larger than the one in the foreground (maybe even twice the size). This was originally published in Roger Shepard’s book “Mind Sights” in 1990. In […]
In this new twist on an old optical illusion, two spaceships can be seen flying through a wormhole. The spaceship in the front appears to be significantly smaller (maybe half as big?) than the one behind it. Surprisingly, however, both spaceships are the exact same size. The wings of the spaceship in the back are […]
The sphere that is placed closest to you looks to be about half the size as the sphere in the background. Surprisingly, both spheres are exactly the same size. If you don’t believe it, grab a ruler and measure them both to confirm. For a similar effect, be sure to revisit the SUV Illusion where […]
In this brief video from Scientific American, the Ames Room illusion is demonstrated and then completely revealed. If you are not familiar with an Ames Room, first have a look at this vintage Ames Room illusion photograph. Now watch the video and see exactly how this trick is done.
Perspective matters. The angled lines in the animation presented below give the impression that the floor is sloping downward to the left. As such, the man standing on the left appears to be much shorter than the man standing on the right. As the man on the left walks up the incline to stand directly […]
Have you ever looked up at the moon in the night sky only to think that it is bigger than normal? Is it possible that the moon is actually closer to the Earth on these nights? If you measure the size of the moon on any given night, it is always the same size. Our […]
