Science Experiments for kids Solar Energy with Dr. Shnitzel's Wacky Science part 2

[Music] When it's sunny. outside. There's another activity we can do, but for this you're going to have to have your parents watching you very carefully because it could be a little bit dangerous. You're going to need a white and black paper. You have a magnifying glass. We're going to try to magnify, which means enlarge the light of the sun through the magnifying glass on the paper. We are going to see if the magnifying can make the light of the sun so hot that it actually burns a hole through the paper. The question is, what color paper do you think will light faster on fire? White or black? We are going to start first with the white paper. Let's take our magnifying glass and ooh, as you can see over here, let's bring it a little bit closer. As we get closer, it gets bigger. So, we're going to try to go further and make a very small little light source and try to be as steady as we can. And it seems like we are not. Did we do anything? Nope. Okay, let's try now the black paper. We're going to try to do the same thing. We're going to try to be as steady as we can and let's see what we get. [Music] Okay. [Music] Oh, look at that. You guys see that? We are burning straight away. It catches on fire. I'm going to place a rock down so we don't burn the wood of our deck. So, we're going to put this down over here and let's see if we can continue [Music] Look what I made. It says, "Wow." And if you turn it over this side, it says, "Mom, that was amazing. But is this big enough for Dr. Schnitzle?" Everybody say, "No, we have to do it bigger." But do not try this at home. For this, you need to have your parents watching over you because it could be very, very dangerous. I took this from a cover from an outdoor heater. You see, this is the cover of the outdoor heater. And look what I put inside. I put in mirrors. You see that? All these mirrors. And because all the mirrors are on a curve, they're going to flect back to one single point. So, I'm wondering if I take a black tissue and I put it over here, are we going to get a single point of the solar energy and then we could perhaps start a fire? Should we try to do that? Okay, let's see. This is a little hard. Got to get exactly the right part. Oh, I think it's going. [Music] Mendy and Mayor, do you guys ever like going camping? Yeah. Amazing. Dr. Schnitzer likes going camping. And we make a nice big bonfire and we have hot dogs. Who likes hot dogs? Yummy. And after a couple of days of camping, 1 2 3 4. Oh boy. we start to smell like Dr. Schnitzle smelly socks. So, what do we need to do? We need to take a shower. This is called a shower. We can use the sun not just for having a good time in the sun, but we could use it for warming up our water. See, because this is very dark, we fill it up with cold water from the stream. And look, we let it sit in the sun. And look over here. I've been letting this sit in the sun for already 3 hours. And look how warm it is. It says over there it is 98°. And look, you could take it, you could hang it up over a tree or something and then or a branch. And look what we have. You take this over here. And now you can give yourself a shower. Look at that. Here we have a shower. Hey, come back over here. Come back over here. Oh, look. You can turn it on and off. On and off. And if you need a wash for bread, what do you do if you have water to wash for bread? Oh, what happens if we take this off? Shall we see? Yeah. Let's see. I don't know. Is this a good idea? Oh. Oh. Oh no. Oh no. Oh no. Who here likes to have water fights? Look what I have. I have a Dr. Schnitzel water bottle. This is for you and this is for you. Have fun. [Music] We're going to do an experiment now to see if hot air rises. So, I have over here a whole bunch of tea bags. We are going to take these tea bags. We're going to open them up and rip open the top like this and pour out everything the tea substance that's inside. See? Just like this. Yeah, beautiful. Now, we are going to carefully tear this in half and we're going to open it up like this. Here we have our little teab bag material. It's going to go one here and one over here. See? Beautiful. Now, what Dr. Schnitle is going to try to do is I'm going to try to light it on fire. And if hot air rises, this should this tea bag should float up until it burns out. But of course, you have to have adults watching over you if you're doing it. And of course, fire safety, a fire extinguisher. So, let's see if it's going to go. Let's see. Is it going to go? Did you see that? Amazing. Let's try this one. Oh, is it going? Oh, look at that. It goes up with a fire. The hot air rises. Here I am in this beautiful field. Look at this. And there's one thing I like to do, especially if it's a little windy. I like to fly a kite. Here I have a fishy. What's the fish's name? Uh, let's call him Uchka Buchka. Let's see if when the wind picks up, we can start to fly this kite. So, let's go. Come on. Let's go. Go up, up, up, up, up. Come on. Oh, there it goes. There it goes. Yeah. Look at that. It's going higher and higher. Isn't that awesome? Amazing. I wonder how high we could have it fly. No, don't fall. Don't fall. Oh, there you go. Let's see how high we're going to go. Yeah, look at that. It's going. It's like 100 ft in the air. Oh, I could do this all day. This is so much fun. Flying a kite was so much fun, but I'm wondering, is it possible for us to have a black garbage bag fly up high in the sky using the energy of the sun? As we said before, black attracts the sun. So, if we fill this up with air, the sun will shine on it and it's going to make the ear inside very hot and slowly maybe it will fly up high in the sky. So, let's open up this bag. And where's the wind? Oh, there it is. Okay. Okay. Oh, yeah. So, we have a string tied to it. And let's see. Oh, I guess you don't need a kite if you want to fly something. You can take a garbage bag and a string. But the question is, will the sun make it fly up high in the sky? Because the kite had wings, so it's able to fly. But this has no wings. But if I let go, it falls. If it's windy, you can definitely have a good time with it. Look at that. But it's not going high. Looks like the bag is too thick and there's not enough hot air. So, let's get a bigger bag. Oh, it's going. It's going. Let's see. Let's see. Hey, up. Up. I said go up. Go up. It's not going. Let's try it with a bigger bag. Here we have It looks like a garbage bag, but is it a garbage bag? No. It smells like a garbage bag, but is it a garbage bag? Everybody say no. It's actually called a solar bag. That's right. Look at this. or a solar tube. See that over there? Solar tube. Now, what I'm going to do is we are going to tie this side over here a nice knot. And this is a very thin bag. So, we're going to see if we can fill this up with air. Sun shine on the black bag and make the air very hot and come like a hot air balloon and fly in the sky. Are you ready? So, we got to get the air inside. How are we going to do it? We got to run around. We got to run around. I think it's going. Yeah. Oh, there you go. It's going. It's going. It's filling up. Oh, yeah. Okay, good. We have our big tube. We are going to make a knot over here just like this. And we're gonna allow the sun to shine on our big black solar tube. Look what I have here. Should I let go? Let's let go. Oh, look at that. Oh, it's getting hot. And it's flying. I don't want it to fly away. Look at that. Yeah, it's getting very, very hot. As you can see, it's expanding. Oo, it's hot because it's dark. It's black. And black attracts the sun. And now, let's see. It's going to float. No, don't run away. We have our big solar tube connected to our kite stream. Now, the question is, will it start to fly just using the power of the sun? Oh. Oh, look at that. It looks like it's going. Yeah. How high do you think we can get it to go? Oh, the wind is making it go flying all over. Let's see. Hey, calm down, wind. Look at that. Look at that. A flying hot dog. A flying hot dog. But we want it to go up high. Come on. Oh, there you go. Whoa. Come on. Up. It's high. Float. Higher. Higher. No. Not down. Up, up, up, up. Come on. [Music] That was a 20ft solar bag. But look what I have over here. I have a 60 ft solar bag. And for this I'm going to need my helper. Actually, no. Uh, he's auntie as a soldier. Whatever. Hey. Hey. He's coming with me. No. Come back. Okay. You ready? Okay. Here it goes. It's very windy and this is 60 ft long. So, we're going to need your help here. Okay. So, let's open it up slowly. And it's very, very thin, which means if it has the slightest tear, we can't use it. Okay. So, here, hold on to this side very carefully and start walking that way. Walk, walk, walk, walk, walk more, more, more. Keep on going. Keep on going. Yes. More. More. More. That way. That way. This way. Yes. Keep going. More. More. More. More. More. more. Look how long this bag is. Oh my gosh. Keep on going. Run, run, run, run. Whoa. Come back here, Andy. Wait. Stop. Did you just trip? Oh, man. Over here, we got a 60 ft long tube. Look at that. Let's see if it's going to go flying up high in the sky. If I let go, how high can we get this to go? It needs a lot of sun. Oh, I think it's coming. Come on, go high. Yeah. Whoa. Yeah. Amazing. Look at that. The heat from the sun is warming up the black bag, making it float higher and higher. [Music] Oh, look at that. Yeah. [Music]
