We ALL love a good optical illusion, so this one will challenge you.
The “Impossible Roof” video puzzle shows what happens when you place a ball on the roof of a model home.

But instead of rolling, the ball defies the laws of gravity and dances around the edges before landing, still on the ceiling.
Its creator, Kokichi Sugihara, a professor at Meji University in Kawasaki, Japan, explains to lainformacion.com: “The brain interprets that the two eaves have the same shape.” ‘Squaring’ is an example of symmetry, and in the case of an impossible roof, the symmetry is created by building the axis to be perpendicular to the side of the roof.
dr. Sugihara said that he works with computer software that uses two-dimensional drawings as three-dimensional objects.
He explained, “Sometimes the program would turn these objects into real objects, and that’s how I found out that some impossible objects aren’t actually impossible, they can actually be built as solids in three-dimensional space.”
This isn’t the first 3D optical illusion a mathematician has created to make fans question the laws of physics.
He’s after an awesome mirror puzzle called “ambiguous cylinders” that turns squares into circles.
In another clip, a set of plastic squares is placed in front of a mirror, but instead of reflecting what we see in front, the glass reflects a cylinder.
Interestingly, when the shape is rotated, the images are reversed.
To make matters worse, the video shows the addition of more symmetrical shapes, creating a whole new illusion.
A set of four squares becomes overlapping cylinders, and two interconnected squares become two separate cylinders.
The illusion earned the professor second place in the annual illusion of the year contest.
Fortunately, you can stop scratching your head because another clever scientist has discovered that the secret behind the confusing images is “reverse engineering.”
Devon, from 3D printing company Make Anything, demonstrated that one side of each cylinder is shaped like a square and the other is more circular.
