25 Superb Optical Illusions For Kids
An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality.

There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, color, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences. These optical illusions for kids help them in increasing concentration power and sharpen their focus.

CAE Reading Part 3: free practice test The Sahara Film Festival After a bumpy 225km drive from a meagre airstrip in Tindouf, south western Algeria, a sprawling single-story town begins to emerge from the desert’s dust.

But despite the energy and excitement, the background to the film festival is a serious one, as the Sahrawi people have been living for thirty years in this isolated desert outpost, having been forced to flee their native Western Sahara.
