Transcript for The author of 'The Dad Lab' teaches Keke and Michael about the properties of water
fun with at-home science projects. Please welcome the creator of "The dad lab," sergei urban. Sergei, experiments get a little messy. We have some protection on. What do you have for us? I'm going to show you this simple experiment that you can do at home and we'll learn about the properties of water and other objects. You need two glasses, sticky tape, make sure the string is wet and you put some water in one glass. I always prefer to use color so we can see the water from the outside. What you do now is basically pouring from one glass to the other. Oh, my goodness. The water just goes. Just like that. Now, how does that do that? It looks like something simple you can do easily. That's why, a challenge with helmet. This one goes on top of you. It does? Yeah, yeah. Let's put it on. Whose idea is that I'm the one wearing this? Mine. Yeah. Always buckle up for safety. Move right here. Keke, if you can just get on top of the ladder here. I want you to do -- you're a big guy, you have to sit down a bit. Let me get on this side. I'm going to fill the glass with water. Hey, man -- You should be all right. Don't worry. You're going to be all right, you're going to be all right. We need to make sure that the string is tight. The string is wet. It's wet and tight. Okay and doing it slowly -- slowly, slowly. It's going. Yeah. Wow. Yeah, how neat is that. Oh. A little bit of mess. A little bit. I forgot there was liquid in there. When you're playing with your kids, it's worth it. You know, that was something else. You're over here laughing. I got something for you, too. It's not over. For this one is basically bag of water -- plastic bag of water. Keke, do you trust science? Sometimes. Okay, sit down and relax. And if I were you, I would put my hood on just in case. And so what we're going to do now is, we're going to take those pencils. Don't worry. Okay, so what we're going to do now, if we're careful we're going to put the pencils through the bag and if we're doing it right the water should stay in the bag. The water should stay in the bag. If you're doing it right. Can you do one for me? To show me what's right. Do I go fast? Try your best and just be Try your best. Is it something slowly -- Slowly is fine, okay. Okay. Get a countdown. Three, go -- I'm going to say a prayer, I don't always trust science but I always trust the lord. I need a countdown, three, two, one -- whoa. Okay, let's try that again. Make sure you have a sharp pencil, though. Yeah. Anybody in the audience want to do this? Come on, come on up. Come on, man. Here we go. Here we go. Try that. Try that. Just be careful. Yeah. Wow. Thank you. Thank you. And you know, the cool thing about this experiment, when you take the pencils out the water still stays in the bag. It does? I'm just joking. Oh. You know what, that is actually really cool except for when you take the pencil out. You lied to me. All right, you guys, you can find all of sergei's experiments in his book "The dad lab," which is available in bookstores everywhere.
