Science Experiments for kids Liquid Nitrogen part 2 with Dr. Shnitzel's Wacky Science

Heat. Heat. Here we are on the floor in Dr. Schnitle's house. We have a beautiful Dr. Schnitzell logo picture. What we're going to do is we're going to put this on the floor. And because we have over here this dark background, I wonder what would happen if we take some freezing cold liquid nitrogen and pour it on top. We should see little balls going all around. Let's see what happens. Here we have a whole bunch of beautiful colorful candles. Not just the candles are colorful, but even the fire is going to be colorful. Have you ever seen colorful fire? That's going to be for a Dr. Schnitzle video coming up very soon. Stay tuned. I wonder what happens if we take fire on a candle and we put it inside liquid nitrogen. Do you think it's going to make a big explosion? Or do you think it's going to catch on fire? Remember, anytime you're doing this, you have to have your parents watching, helping you. Never do this on your own. So, we're going to take a look at all these beautiful candles. What color should we do? Should we do yellow, purple, green, pink, blue, or orange? I think we're going to do green for Dr. Schnitle's here. Okay. So, let's open it up. Just like that. And here we have this green nice candle. Okay. So, we're going to light it carefully. Ooh. And let's see what color the flame is. Let's see. Oh, let's see the color. Here it goes. Let's see what happens if we put it inside. And it goes out. Why does it go out? Because fire needs oxygen. But in here, there's a whole bunch of nitrogen. Because remember, this is liquid nitrogen. It's the gas that's all around. There's no oxygen inside. So every time we take a fire and we try to light it here, there's a whole bunch of oxygen. But if we put it inside, let's see. Watch this everybody. Just like that. Here we have a whole bunch of pennies, quarters, nickels, and dimes. Can anyone guess what pennies are made out of? Well, it used to be made out of copper. But 1982, that's the year Dr. Schnitle was born, they swapped from copper to 98% zinc. So these pennies over here, if they're old, like let's see what year this is. Oh, this over here is 1990. This is mainly zinc with a little bit of copper on the outside. But if we can find a penny that's very, very old from before 1982, it actually is made out of copper. But why should we care? Well, what happens if we take pennies and put them in the liquid nitrogen? So, let's see. This one over here is made out of hm from 1990. Let's put them inside. And let's see what happens if we put this one here is from 19 79. We're going to put a whole bunch of pennies inside. Look at all these pennies. Oh, yeah. Yeah. Yeah. We're going to put the pennies. You know what? Let's also put a quarter inside. And we're going to put a nickel inside and a dime inside. And let's continue to put a whole bunch of pennies cuz this penny over here is shiny. It's made. It's 2019. Let's see how the pennies are cooking. They're cooking inside. I was told that copper is a lot stronger than zinc, which means that if we take a hammer and we hit the pennies that are old pennies, they should be very, very strong and not crack. But what happens if we take the newer pennies? They should crack in half. Should we try that? Ooh, they're so cold. So, let's see what pennies we have. This one over here is from 1979. So, we're going to take this here and h they're not working. Hey, but look here. We have a penny from 19 from 2019. Let's see. Oh, did you see that? It cracked in half. But let's go back to this one from 1979. The old one. Oh, no matter what I do, let's try this penny over here. It's so cold. This one here is from 2017. Let's see if it cracks. The zinc pennies, the newer ones are cracking. Let's try. This is What year is this? This one over here is from 1997. Let's see. This one also should crack, I think. Yes, it's zinc. Let's find a old penny. Ooh, this. Look how old this one is. This one here is really, really old. You see that? Let's see if it cracks. It's from 19. Hm. I can't even tell. Doesn't crack. What about a quarter? Do you think a quarter will crack? Nope. Doesn't. What about a nickel? A dime. Let's try a dime. Doesn't crack. But an old penny. Old penny doesn't crack. New penny. Here we have a whole bunch of bubbles. If it's true that this beaker is full of nitrogen, when we blow the bubble, it should float on the top for maybe one or two seconds. Let's see if that works. But wait, what's this? Let's see. Oh, maybe this is going to make a big bubble. Watch. Hey, stuck. It popped. Let's see what happens again. Let's try that again. Yeah. So, let's see what happens if we blow a bubble in liquid nitrogen. Let's see what happens. Oh my gosh, look at that. Did you see that? Another amazing experiment we can do with liquid nitrogen is what happens if we take a little needle. Oh, very, very sharp is to be careful. And we poke a hole in a pingpong ball and then we take the ping pong ball and put it inside a liquid nitrogen. The liquid nitrogen will go inside the little ball. And I wonder what happens as the gas wants to expand. It's going to come out. And if it's coming out this way, cuz the hole is here, it should shoot the ping pong ball that way, right? Cuz if it's push, if the gas is pushing this way, the ping pong ball will go that way. But what happens if we don't make a hole straight? What happens if we make a hole on the side? Oh, perfect. And now we're going to take this and we're going to hold it down and try to get as much liquid nitrogen as we can inside the ping pong ball. And let's see what happens. Now, let's take it out and see what happens. Look at that. It's spinning. There you go. Look at that. as the ear is trying to come out because it's on the side. It's making it spin. Come back over here. It's like a little drrele. A look at that. The spinning ping bong ball dr. OH MY GOSH, LOOK AT IT. IT'S going on its own. Amazing. Hey, is it going to land on a nun, a gimmel, a Hay or Shin? But there are no sides. I guess nobody can win. Look at that. It goes faster and faster and faster. The gas is going out this way, so that's why it's making it spin the other way. What are we going to do with the leftover liquid nitrogen? Well, I have an idea. Let's pour this inside and quickly say 3 2 1. Ready, set, ready, go. AND AMAZING. Look at that. Oh no, now we have a mess. Who's going to clean up the mess? Dr. Schnitzel. Everybody say no. Oh my gosh, look how awesome this looks. Isn't that amazing? Look. Isn't that awesome? Let's see what happens if we take popcorn and Froot Loops, put them in the liquid nitrogen, and then put it in our mouth and then we begin to talk. I wonder what's going to happen. Hm. Let's start with the popcorn. So, we're going to take some beautiful golden float popcorn. Just a little bit. Yeah. Just like that. Yeah. Yeah. Yeah. We're going to put it inside. Who knows what braha we make on popcorn. That is right. By prima. Good. Now, what we're going to do is we're going to take some of it out. We're going to shake it around so it doesn't so there's nothing left inside. And then we're going to put it in our mouth. Hi. How are you? How are you? It looks like you're breathing in the cold with a whole bunch of smoke coming out of your mouth. I wonder what happens if you do it with Froot Loops. Let's take a whole bunch of Froot Loops. Now, we know that we're not allowed to talk when we eat, when we have food in our mouth. So, don't talk when you have food in your mouth. But we're just doing this now just for the science experiment. We just want to show what happens when we talk with some liquid nitrogen cereal in our mouth. Oh, look at these amazing colors. Yes. Yes. Yes. Okay, I think we're ready. We're going to take a whole bunch of this. We're going to put it over here like this. Just like that. And how are you? How are you? Buffalo pickle. Buffalo pickle. So yummy. Should we do that again? Let's go like this. I could do this all day. It's such yummy breakfast. Hi. How are you? How are you? Hi. I love eating sil. Let's do it with our boys. Yeah. Okay. Here. Let me try some of this. Look at this. Let's put this in our mouth. Hold on. Hi. How are you? How are you? How are you? >> Does anybody want some? >> Yeah. >> Okay. Hold on. You're going to put it in your hand. When I say go, you're going to put some in your mouth. Okay. How are you? >> Let's try cereal. Look at that with the spoon. >> Should we eat it for breakfast? Okay. Look, look, look. Watch. You go like this and you go. for you. For you. Is it too cold? Wait. Don't put it in. You have to wait a minute. Let it cool a little bit. Look at that. It's so yummy. Put it in your mouth and talk. Put it in your mouth and talk. Okay. >> How are you? How are you? >> Mayor, we had so much fun with all the liquid nitrogen. But should we make a flying liquid nitrogen rocket? >> Yeah. >> Yay. Okay. The first ingredient we're going to need is some water. We're going to pour a little bit of water. Just like that. Yes. Good. Then what we're going to do is we're going to take our liquid nitrogen and we're going to pour it inside. Are you ready? Okay. Watch here. Oh yeah. We're pouring more, more, more, more. Just like that. It's It's coming out. >> It's going to be a rocket. >> Yes. And this will be a rocket hopefully. Let's see. Let's pour a little more. >> Yes. Okay. Now, mayor, quickly go run over there. Run, run, run. Good. Good. Good. Good. We're just going to pour a little more. And we're going to close this. And are you ready? Say, ready, set, ready, go. >> Ready, set, ready, go. >> And whoa. in. WA. That worked, but it didn't go so high. Okay. One, two, three. Are you ready? And here goes. And Wa wa. Okay, here it goes. WHOA. WA! Where are my three frogs? Where are my three frogs? Are my three frogs in here? They're not in here. Where are they? Where are my three frog? Oh, there you are. Hello. Hello, my three frogs. Are you ready to see a big explosion? >> Yay! >> Who likes explosions? We're going to first take a whole bunch of liquid nitrogen. We're going to pour it inside this bucket. Then, when I snap my fingers, you guys are going to go run to that wall with that and hold it over there by that white wall. Okay? And then, Dr. Schnitle is quickly going to put on this cap on top of my head to protect Dr. Schnitle's face and then we're going to put the hot water inside very quickly and we're going to have an explosion. Are you ready? >> Yeah. >> Okay. So, the first thing we're going to do, we're going to open it up like this and we're going to pour some liquid nitrogen. How much should we pour inside? A lot or a little? >> A lot. >> And now, say after me. Ready, set, ready, go. >> Ready, set, ready, go. >> AND Isn't that amazing? AND come over here. Come over here, everybody. >> We're now going to make an explosion. Oh my gosh, it's going to be awesome. We're going to take liquid nitrogen, pour it inside this Coca-Cola classic bottle. We're going to close it up. It's going to build up pressure. We're going to put the bottle quickly inside over here. Then we're going to pour all the ping pong balls. 600 ping pong balls inside. And we're going to run away and we're going to see what happens. Are you ready? Okay. But wait a second. We have over here Coca-Cola Classic. We have to get all the Coca-Cola out. How are we going to get the Coca-Cola out? Look what we're going to do. We're going to put this over here. Just like that. Yes. Yes. And here we have we have Mentos. Who likes Mentos? Let's put some Mentos. Like that. Just like that. Yes. Yes. Yes. And hey, come back over here. We're going to go like this. And everybody say, "Ready, set, ready, go." Ready, set, ready. And let's see what happens. Look at that. Amazing. Now we have a nice empty bottle. Let's take some liquid nitrogen and we are going to pour it inside our bottle over here. Okay, I think that's enough. Let's see. Is it going? Cover your ears. OH, wasn't that awesome? It's now time for us to make a big explosion, but we're going to add some shape. Everybody say >> and we are going to add some paint. Are you excited? The first thing we're going to do is we're going to take the soap and we're going to pour it inside over here. The whole entire thing. Ooh, that's going to be a lot of soap over there. Yeah. And then we're going to take a whole bunch of paint. Ooh, that's a lot of paint over there. Okay, we're going to pour a whole bunch inside. Are you ready? Here goes. Look at that. Look at this big mess over here. A amazing. Look at this awesome cloud. It's floating and going and going. Oh, this is amazing. >> Ready, set, go. And Heat. Heat. Now we are quickly going to hold it like this. And it didn't work. blooper because I'm holding it. I think what we need to do is put more inside. Water and more. A third time will be a charm. It's making a lot of good bloopers. Hey. Okay, guys. This is it. This better be it. Are you guys ready? One, two. Say after me. Ready, set, ready, go. >> And >> I think that's called a fail. >> Ready, go. >> Okay. Oh, what happened? >> What? >> You ready? Okay, here it goes. 1 2 3 go. We are now going to take liquid nitrogen and we're going to pour them. Hold on. Let's put this over here. Okay. Okay. They switched from copper to zinc. Now pennies are made mostly zinc with a little Hey, it's not a penny, it's a dime. All right, let's try this again. Mo man, you guys did such a great job. Please pick up your hands and give yourself a big tap on your back. This was so much fun. You guys deserve special Dr. Schnitzle presents. Here we have for each and every one of you a Dr. Schnitzle water bottle. And here we have, would you like a color changing Dr. Schnitle cup? >> Yay! This is for you. This is going to turn blue. And of course, each one of you are going to get a whole pack of Dr. Schnitzle stickers.
