 Welcome back to Kids Fun Science. My name is Ken. Today's experiment is CSI strawberry DNA. As always adult supervision is required. What you need for this experiment is three strawberries, rubbing alcohol, measuring cups, salt, water, dish soap, bowl, funnel, skewer, zip lock bag, and a test tube. Welcome to Kids Fun Science. Today we're going to be extracting DNA from a strawberry. All right, and we have our helpers are. All right, so what do we need to do first? We're gonna make a solution, right? All right, so we need to mix one half tablespoon of salt and one third cup of water. Okay, one half tablespoon, one third cup of water, and one half tablespoon of salt, and we're gonna put that as a mixture, right? We're gonna use later, so we have to prep this first, so he's getting the salt going there. It doesn't have to be exactly perfect. There we go, that looks good. I got the water. Okay, go ahead and pour those in. One third cup water, and then we also need one tablespoon of dish washing, dish soap. So extracting DNA from a strawberry. I've never done this before, so as all experiments. This might take a few tries. Okay, there you go. One thing, at least the salt would be clean, right? Because we have soap in it. All right, so we can stir that around a little bit. There you go, nice and gentle. We don't want to get in bubbles just like that, perfect. And we kind of make sure the salt, you see any salt crystals in there? We want to make sure they. You do? Okay, we'll keep stirring that until they're all gone. I'm gonna stop for a second. So what we're mixing right here, Hayes is mixing is the extraction liquid that we're gonna use later. Okay, so it looks like it's almost there, still kind of there. Yep. Okay, all right, so once we get that done, we'll step on to the next step. All right, so now we're going to the next step. What are we doing? We're taking off the tops of the strawberries. Okay, go ahead and take those off. Nice, perfect. Two strawberries, one hand, good. All right, now what are we gonna put them? We're gonna put the strawberries in the bag. Okay, go ahead and put them in a zip lock bag. And then we have to make sure what comes out of the bag. Yeah, so kind of almost, yeah, squeeze it all out, there we go. Now for two minutes, we are going to smush the strawberries. You don't want to break the bag, but we want to smush them. Nice, squeezing you. I'm not timing it, but I'm looking on the recorder here, so I'll watch how long. I could, huh? That's good, I think I'm gonna have a strawberry now. So we're gonna do this for two minutes, and then we'll come back. So now we are gonna be putting three tablespoons of this mixture into the bag. Okay, the ones we made earlier, the extraction liquid we made earlier, right? Yes. There's one, two, and three. Now, this time, how long do we, after we get the air out of the bag, how long are we gonna squeeze it up? One minute. Okay. All right. I don't think I've ever squeezed strawberries this much my entire life. All right, so we'll come back. We're gonna let you do that for a minute, and then we're getting ready to filter out all the excess of the strawberries. We'll be right back. All right, so now we're gonna be pouring all this liquid into the funnel so that the solids will stay on top, and the liquids will go down. Okay, so let's go ahead and maybe might have to hold. So we're pouring that in there. It's all the three minutes of squeezing. Oops, I spilled. It's not an experiment unless we get messy. There's some drops leaking down there. Is it coming through? Yeah, it's starting to come through, huh? Yeah. Very slowly, though. Yeah, that's fine. It'll go through. There's a lot of liquid there, so we'll check back in a second. So, into the bag. Okay. Take the funnel out. Okay, so we can see how much juice got in there. Yeah, there we go. So it's all strained out. Good, good. And now I'm gonna get some rubbing alcohol and fill it half cup, and that's good. One second. Now we're gonna be using the pipettes and taking out the rubbing alcohol and slowly putting it in on the sides of the strawberries. Perfect. Yeah, because we just wanted to rest on top of the strawberry, right? As you can see, it's going, you guys are going perfect. It's going right on top, and it's extracting the DNA. We're gonna make a strawberry monster. Good job, guys. That does look cool. I feel like it kind of looks like a lava lamp. Good job. Go a little bit higher. We probably won't use the whole half a cup, but... You know, strawberry lava lamp. Okay, one more. Finish both of those and then we'll stop. Go. All right, now we are going to be examining the strawberry juice and putting the bamboo skewer into it. And we see some stringy white stuff that's probably the DNA. Okay. So let's extract it, but don't put it in. Yeah, try to grab some of that. Scoop it up. Can you scoop? Try to scoop it in. But don't try to get any of the strawberry. Let's see. You're getting it. There you go. Oh, cool. So we extracted some DNA from a strawberry. All right. That's awesome. It's a little too close. Cool. Now you guys want to try to pull more out? That's cool. Nice. It doesn't really look like DNA. But that's pretty cool. I thought I'd see some like cool like spiral stuff. Yeah, well maybe under a microscope, which we don't have unfortunately, but that's pretty cool, huh? Yeah. So you're able to pull it all out. It's just on the bottom and sitting there, huh? I wonder if we try to get some of the strawberry, what will happen? I don't know. We can try that in a second, but we want to make sure we can do more. I want to try it. Let me see what it feels like. I can't really, it doesn't really have a feel. Oh, there. It's a little solid. As I say, after I squeeze, I can feel a little bit. I get a little bit of it there. Okay, let me cut it. But now we're putting it, trying to put it into the red stuff, and we're going to see what happens. Okay. And it looks like we're getting more of a reddish DNA. That's so cool. Like you get it, and then once it comes out of water, it just goes down. Yeah, because the mass is more heavier. All right. So you guys ready to have strawberries later? No. All right. So the observations and the results were we were able to see the DNA in the test tube when we added the cold rubbing alcohol, the DNA mostly layered in the alcohol in between the layers of the alcohol and right above the strawberry liquid that we added. When we added the salt and detergent mixture into the smashed strawberries, the detergent helped pop open the strawberry cells, releasing the DNA into the solution, whereas the salt helped create the environment where the different DNA strands could gather and clump, making it easier for us to see them. When we added the salt and detergent mixture, you probably mostly saw the bubbles form. It's in the bag because of the detergent. After we added the cold rubbing alcohol to the filtered strawberry liquid, the alcohol should have participated the DNA out of the liquid, while the rest of the liquid remained in the solution. That's when we were able to see the white, clear, gooey DNA strands in the alcohol layer as well between the two layers of the strawberry liquid. Single strand of DNA is extremely tiny, too tiny to see with the naked eye, but because of the DNA clumped in this experiment, you were able to see how much of it in the three strawberries we had when all the cells were combined.

I'm in the logging and I love your videos and I also want to make a shout out to Lance Stewart. Hope you're doing good man with that car crash and hope you feel better. All right. Also check out my channel. It's minecraftgamerb. It will probably be in the link below. And shout out to my friend at M&M. All right. All right guys. Thanks for watching.
