Explaining Optical Illusions: Part 4 - The Ebbinghaus Illusion and the Flash lag effect

In this video I take a look at 2 optical illusions and explain why they fool us. Firstly, I will look at the Ebbinghaus illusion which shows a central circle appear to grow and shrink as circles surrounding the inner one change in size. I will also have a look at the flash lag effect in which it appears that a flashing image lags behind a constant one.
