Optical Illusions…

• Optical illusions happen when our brains wrongly interpret what we are seeing. This can happen in a number of ways. For example, on a hot day you might sometimes see a mirage which appears like a sheet of water. This is caused by the light from the sky reflecting off a layer or hot air, our brains think the blue colour of the sky is water!
