Work You Explained Clearly

Is there magic, uncle? Not magic. Amazing! So, how does it work? Sorry, it's a secret. Cool! Maddy, you need your goggles. Got them. Wow! Awesome! Super fun! Wow! How does it work, uncle? Uh secret. Oh, sorry. Secret again? Let me show you another trick. Woohoo! Wow, that's so cool! Cool, how does it work, uncle? Let me guess, secret. You got it. It's a secret. Uncle, please tell us.

What's the point? He's never going to tell us. Science isn't fun if you don't know anything. I guess you're right, Maddy. Let's go home. Wait, stop. Uh if you girls answer my science questions correctly, I'll tell you how it works. Deal. The floating paper clip challenge. Cool, how's it doing that? What? The challenge is to make the paper clip fall without touching it. I'll go first. Not so fast. You have to do so by choosing one of these objects.

Hmm. Oh, I'll choose the stick. It's not working. Uh sorry. Aw, I didn't get it right. Who's next? I'll choose the water bottle. Your turn, Eva. Well, it's not working. Sorry. Aw, it didn't work. Maddy, have you made your choice? Which one should I choose? Ow! Maddy! Yeah! Looks like I'm telling you all the secrets. Yay! By placing the opposing pole onto the other magnet, it neutralizes it.

Wow. Amazing. This is ferrofluid. The spikes are formed by phenomenon known as normal field instability. It happens because of the fluid is trapped in a tug-of-war between three competing forces. Wow. Magnetism, gravity, and surface tension. The fluid gets pulled towards the magnetic field lines, and that's why it looks like that. Oh. The magnetic force passes down the chain is keeping them together. Aha. That's why only the bottom one will spin. Even with a lot of effort, the force is too strong at the top. It won't spin.

Now, who wants to try? Me. Super fun. Yay! Woohoo! Yay! Good job, Bella. What about the magic slime? That we'll have to make. Wow. The slime reacts to the magnet because of one secret item, iron filings. We'll put the iron filings into the slime. Ooh. Awesome. Huh? Why? It's not working. It's because we're missing the secret ingredient. The magnetic force attracts the iron filing, which pulls the slime with it.

Amazing! Cool! Thanks, Uncle. Yep, and now you know my secret. Awesome! And it's not over yet. Wow! [screaming] Check it out. Let's go. Check it out. My cool experiment. What's the experiment, Uncle? Check this out. Why is the coin not drop? Because the coins are magnetic. That's correct. But, check it out. Yeah! I love it. Yeah, this is my best experiment. Oh. Oh, little Mike, I got to close. Sorry. Sorry, I guess we'll have to go home now.

Aw. I really wanted the magnetic slime. I want the coin experiment. I think I could do an experiment for you. Oh, I love slime. Woah! Now we put some sprinkles. And now we add some blue. Yoohoo! And now we add the magnet. Only do experiments with adult supervision. Is the slime magnetic yet, Uncle? Not yet. Watch. Huh? We add iron filings to make it magnetic.

The iron filing will make the slime magnetic. Huh? Awesome! Woah, that's interesting. Uncle, do magnets attract to everything, like wood? Let's try it, Alex. Nothing's happening. Magnets don't attract to glass, plastic, or wood. Uncle, can you do the coin experiment? Sure. Hmm, this should be easy. Connect the coins right here. Uh-oh. Don't worry, I got it this time. Yay, it works! Cool!

Wow, does it work, Uncle? Hmm, actually, I don't know. Huh? I know. I'm Uncle Jason, remember? From the science fair, magnetic experiment master. Yeah, we remember you. Can you explain this experiment, Uncle? Sure. The closer you are to a magnet, the stronger the pull is. That's why this coin is so tough. However, the further away you get, the weaker the pull is. That's why this coin over here can spin. Yay! Can you do more experiments for us, please? Sure, no problem. And now, let's see what happens. Why is it floating, Uncle? So, we have two magnets of the same pole, they'll repel each other. That's why you can see that the magnets are floating.

Can the car move, Uncle? Woah. Once again, the same poles push each other. That way, the car can move. Let's see what happens when we change the poles. Opposite poles will attract each other. This is really fun, Uncle. So, remember, fun fact, two magnets of the same pole will repel each other, while two magnets of opposite poles will attract. Hmm, that's pretty cool, but is there anything more exciting? You bet. I'll show you a trick. The magnet can work through your hand? That's another fun fact. Magnets can work through our bodies, as well as through water.

I want to go fishing, Uncle. Okay, go right ahead. [screaming] One. Experiments are so cool. Can we do some more? Sure, check this out. Wow, this is like a UFO trying to land somewhere on Earth. Yes, the swinging magnet is attracted to each magnet as it swings. But at first, it swings too fast for any magnet to capture it. After a while, its swing slows down, and finally, a magnet traps IT. YAY! NOW, this one is pretty cool. Watch. How is it spinning and floating at the same time? Because all of these magnets are facing the same direction, they're repelling each other. But, because these two magnets are pulling this one in the

middle towards each other, it's causing it to float. The same thing happens on the back side, too. These two magnets are pushing the back end upwards, which causes both sides to float. This is like magic, Uncle. Next up, I'm going to build a sculpture out of just a magnet and these. Huh? All right, let's get started. The nuts become magnetic when they're placed on a magnet. In other words, magnets can make other objects magnetic. We learned a lot today.

Uh-uh, it's not over. Cool! A globe? How does a magnet relate to a It's very related. The Earth is one big magnet. Earth is like a huge magnet, too, but way stronger. The Earth has something called a magnetic field that goes all around it. This magnetic field is invisible, but it's like a big force field surrounding the Earth. Just like how magnets have a north and south pole, the Earth has its own magnetic poles. We call one of them the North Pole and the other one the South Pole. They're not the same as the geographic North and South Poles where it's cold, but they're close. The Earth's giant magnet is created by something called the Earth's core. It's like the Earth's engine deep inside. The core is made of hot melted metal

and it's always moving and swirling around. This movement of the core creates the Earth's magnetic field. The magnetic field is really helpful for us because it protects us from the sun's harmful rays. It's like a big shield that keeps us safe. So, just remember the Earth is like a giant magnet with a magnetic field that protects us and helps us find our way. Isn't that amazing? Mhm. That's an amazing fun fact, Uncle. Mhm. Magnetism is real interesting. Thanks, Uncle. We learned a lot about magnets today.

Wow. [screaming] I lost. How about this? Is it going to pop? Not going to pop. It's going to pop. Oh, I lost again. How about this one? Is it going to pop? A lot of nails. It's definitely going to pop. Maybe it won't pop this time. Mhm. We'll see. Why it didn't pop? Yay, I won again. It's magic, Uncle. It's not magic. It's science. Eva, if you get this right, you can play in the balloon house. Yay. Wow.

[screaming] Yay. Ooh. It's not even fun. Now, let's move on to another experiment with balloons and pepper. Ooh. First, I rub the balloon on my hair. Woah! Woah, what's happening, Uncle? When you rub your hair with a balloon, you're moving tiny little things called electrons from your hair onto the balloon. Your hair loses electrons, making it positively charged, and the balloon becomes negatively charged. That's called static electricity. LET ME TRY. AWESOME! WOAH! I HAVE A LOT. My turn, my turn. Woah! This is like magic. Great job, Eva. Now, let's move on to another balloon experiment.

Now, for our next experiment, we're going to guess if the skewer will pop the balloon. Oh, no! Remember, always do experiments with adult supervision. Let's see. Woah! Mhm. How is it possible? Woah! Let me explain. Imagine your balloon is like a big stretchy spaghetti. When you blow air into the balloon, you're asking the spaghetti to stretch out to make room for the air. Now, think about the top and bottom part of the balloon, where you tied it and where it looks darker. Over there, the spaghetti pieces aren't stretching as much. They're more relaxed because they're not holding as much air.

So, if you gently push something sharp, like a skewer, you're asking some of the spaghetti pieces to move aside without letting go of each other's hands. They can do this because they're not stretching too much and have room to move. That's why the skewer can go through without popping the balloon. Wow, that's amazing. How did the balloon not pop in the first experiment, Uncle? If you push the balloon into one pointy thing like a nail, it's like putting all the pressure into one tiny little spot, and pop, the balloon can't handle it and it bursts.

What happens if we have more nails, Uncle? When there are more nails, the pressure gets spread between all the nails. It makes it harder to pop the balloon. So, what happens if we have a lot of nails, Uncle? Well, when we have a lot of nails, the pressure will spread out between every single nail. And here, also. So, it makes it harder to pop the balloon. Oh, now I know. Whew. Popping that balloon made me tired. The same thing happens when you step on a lot of eggs. Awesome.

They won't break. Ooh, I want to try. Me, too. All right, go ahead. It's not breaking. The egg won't break because Ellie's weight is spread between a bunch of the eggs. Okay, my turn. Yay. We learned a lot today. Now, you two can go play at the balloon house. Yay. Whee. Ah. Whee. Look at me. Wow. Whee. There's so much over here. Ice cream. Mhm. Ice cream. Kids, clean up, please. Sorry, Uncle. We'll clean up. We'll clean up, Uncle. The floor is clean now.

Good. You want ice cream? YAY. CHOCOLATE, PLEASE. STRAWBERRY, PLEASE. YAY. Thank you, Uncle. No problem. Mhm. Yay, delicious. Thank you, Uncle. You're welcome. This cone is yummy. Mhm. So good. I want more. I want it, too. No, me first. Me. No, ME. OH, NO. SORRY, UNCLE. Time out. Mhm. It works now. And by the way, time out is over. Yay. So, Uncle, can we have one more, please?

Please. No, sorry. Oh, I got to wash dishes. Ah, Uncle, wait for us. Yeah. I'll wash the dishes. I'll do it. And I'll do it, too. What? No, no dishes. Because I washed them already. Look. I saw they were dirty, so I just wanted to help. Good job, Pearl. You want ice cream? Sure. What flavor do you want? Chocolate, please. All right. One chocolate for Charlotte. Here you go, Charlotte. Thank you.

Yummy. I'm so hungry. Huh? Here you go. Oh, thank you. Mhm. Here you go, Uncle. Oh, thank you. Eat more, please. Let me wash the dishes for you. Yeah. We cleaned the table. Then, all done, too. So, can we have ice cream? All right. One for Ellie, and the other for Eva. Here's your ice cream, kids. What? It's too small. Why? Yeah. Well, too much ice cream is no good for you.

We want ice cream. Me, Me Yeah, me, too. And uncle's not here. YAY, ICE CREAM TIME. I'LL GO FIRST. Strawberry for me. Oh, no. Sorry, I'm being rude. What? Ice cream? I didn't make this. Oh, no. Our ice cream. Ah, follow me. Uncle, what's that? What is that? Ooh, what's that? What? Good. So, no more ice cream. Give it to me, please. Good. Thank you. Aw, no more ice cream. Ah, wait here. I'll be back.

Yummy. Ah, what are you doing, Ellie? Um, I just need water. Bye, uncle. Ellie, you got ice cream? No, just water. Ah, how about we make it again? But, we have no ice cream cone. Wait here. I'll be back. I got it. Yay. [screaming] Wow. ICE CREAM TIME. [clears throat] HI, UNCLE. I told you, one ice cream a day, no more. Sorry, uncle. Stop yelling. Aw. Now, go brush your teeth, please. Sleeping time. Good night. [snorts] BYE, UNCLE. HOW WAS SCHOOL TODAY?

GOOD. SO, who wants ice cream? ME, ME, ME. ALL RIGHT. COOL. YAY, ice cream time. Thank you, uncle. You're welcome. Remember, only one ice cream per day. Got it, uncle. My turn. Ooh, me, too. Kids, stop fighting in the car. I'm sorry, auntie. The plane side, please. Aw. Ew. WOO. SUPER FUN. OOH, CAN I TRY? WOW. [screaming] THIS IS SO FUN. LOOK. WOO. HEY, you're sliding. Sorry, auntie. Aw. Yes.

Amazing. Whee. Hmm, I should fill this with something. Ah, ping pong ball. Yay. Yeah. That's it. That's not enough. I've got ball pits. Ball pits? That's it. That's not enough. Ah, ha, look what I got. Woo. Ah, still not enough. Ah, listen to me. Ah, look at this, Charlotte. My turn. Huh? Sorry, auntie. Kids, no sliding. Hey, do you want cereal? Okay. Wait, I have an idea. Huh? Hm. Tada. Amazing.

Woo. Super fun. Hm. I have a better idea. Huh? Tada. Woo. Super duper. Woo. Ah, what is this? E, let's go get more cereal. Okay. Should we use the whole bowl? Should we? I don't know. I think we should. Let's go. More cereal, please. No sliding, especially with your cereal. Sorry, Auntie.

Look, I colored this. Wow, that's so pretty. I have an idea. Wow. I built us a slide. We can slide these down. We should KEEP IT DOWN. LET'S BE QUIET. WE HAVE TO BE QUIET. AUNTIE WILL hear us. No. Making your own slide. Sorry, Auntie. Aw. Auntie. What do we do? I have an idea.

Done. Kids, meet me in the backyard. Ta-da. Wow. Do you like it? Yeah. Did you build this? I did. Sorry for taking all the fun away. No, thank you for bringing the FUN BACK. YEAH. [screaming] SUPER DUPER. SLIDES ARE FUN but safety is number one. Toy colors.
