 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is the Smithsonian crime scene fingerprint kit and it comes with three different experiments. Ink pads, magnifying glasses, brushes, everything you need to do fingerprint and the forensic scenes, which is pretty cool. What you need for this experiment is the Smithsonian crime scene fingerprint kit, which I have in the description where I got mine, but I also have a couple different areas in case you don't want the whole kit where you can just actually buy the ink pads and get a little bit of information and do it that way. So check the description. So this kit does come with lots of interesting information. Fingerprints are formed five months before you were born and they never change and no two humans have the same fingerprints. So one of the things of the experiment is to be able to document your fingerprints on the detective card that comes with the kit. So I'm using their blue ink pad and I'm doing my fingers where I got my pointer finger and my middle finger and then I will do my ring finger and so you can do right and left hand and then you're able to, with their magnifying glasses, to analyze them. But you can see here the blue was a little bit hard to get off and even when I washed it, it was still there. Now this fingerprint pad, which I have in the description, it just wipes right off. So this is the one I bought. This is not with the kit and I have a link in there. I really like it. It comes off very easily and it doesn't stain your fingers and so that was one of the advantages though. The blue didn't wash off but you can see right here all I do is wipe my fingers together and it's all off your hands and you basically don't have to wash them in any way. So I really like the fingerprint pad ink and that's the one I use. So to analyze your fingerprints, according to the Henry classification system which is used by the FBI, there are eight different basic fingerprint types as you see here. The chart's going to help you compare your fingerprint types with different types. So there are three main fingerprint patterns, arches, loops and whirls. Arches are found in only five percent of the fingerprint patterns. Loops are found more in the 60 to 70 percent of the fingerprint patterns and whirls are found in 25 to 35 percent of the patterns. Besides these eight patterns, there's a lot more classifications from crossovers to cores to deltas and islands which I'm not going to cover in this video but just wanted you to be aware there's a lot more ways that they do analyze fingerprints. So here are my prints on the left hand here and we're going to see I fall into the most common patterns of loops right which is 67 percent and so you're going to see most of mine here are looping right up and you can see almost every finger it's right there so I'm definitely a loop and if I were to compare that against some of my family it'd probably be similar though your genetics don't take over all your fingerprint patterns. So here it is using the Henry classification system by the FBI you can see that I am a left loop so out of the eight that's the one I'm classified at and I could totally see on most of my prints that's exactly what it is so I hope you enjoyed this video if you did please remember to click thumbs up and to subscribe and thanks for watching.
