00:00I think I messed up my experiment, or did I just discover chromatography?
00:04Chromatography is like magic in science.
00:06Imagine you have a messy mix of colors, and you want to untangle them.
00:10You start with a strip of paper and a mixture you want to separate.
00:14Place a drop of this mixture near the bottom of the strip.
00:17Next, dip the bottom of the strip into a solvent, like water or alcohol.
00:21As the solvent climbs up the paper, it carries the colors with it.
00:25Here's the cool part.
00:26Different colors travel at different speeds.
00:29This happens because some pigments stick to the paper more than others.
00:32So, the colors spread out, creating a beautiful spectrum.
00:36This process is called adsorption and solubility.
00:39Chromatography is not just for colors.
00:42It's used in forensics, food testing, and even medicine.
00:45So next time you see a rainbow of colors, remember, that's chromatography in action.
00:49Stay curious, keep experimenting, and who knows what you'll discover next.
00:53Catch you later, science enthusiasts.
