 Welcome back to Kids Fun Science. My name's Ken. Today's experiment is the negative picture illusion, also known as the after-image illusion. This is where we're going to look at a negative and you're going to see color. If you're new to the channel, please remember to click thumbs up and to subscribe. It does help the channel. Thank you. So here are the instructions. Stare at the dots on the woman's face for 30 seconds. I'll count for you. Two, immediately look to the right of the white area and then three, start blinking several times and you should see this woman in color. It's pretty amazing. One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty. Look to the right in the white area and start blinking several times. You should start seeing this woman in color, which is pretty cool. Keep doing it, it'll slowly fade away. That's pretty cool, huh? You should have been able to see this picture in color. Most some people aren't able to though and this comes down to the way our brains interpret imagery and colors in this case of the negative afterimage of illusion, right? So the reason some people are able to visualize this woman in color comes down to the cells in the in our eyes in the back of our eyes called ganglion cells, right? So they're the ones at which sends coded messages to our brain that identify pairs of primary colors. So these codes and colors that come in, there's three different pairs of those and I'm going to go over those. So of the three, there's a black and white, there's a red and green and a blue and yellow, which is the one that comes into play here. Because you stare at the background, right, for a prolonged period of time, as soon as you shift your eyes to the wall or the unified background, the white space, right? In this instance, the cells decline and start to project the opposite color. It being a negative, it goes from the dark colors to color. So those yellow cues, for some reason, as it reveals the woman in the original negative into full color. Pretty cool experiment, huh?
