[00:00:08.03] Now we need your help, [00:00:10.05] and every dollar you donate will be doubled. [00:00:13.06] Sustain the wonder. [00:00:15.01] (upbeat music) [00:00:19.08] - Welcome to the Exploratorium, this is Storytime Science. [00:00:24.04] My name is Viv and today's episode is magnets. [00:00:29.05] We're gonna be reading "Mr. Pack Rat Really Wants That" [00:00:34.05] by Marcus Ewert, and it's illustrated by Kayla Stark. [00:00:39.04] (upbeat music) [00:00:42.03] This book is about a magical magnet, [00:00:46.01] and we know that magnets aren't really magic, [00:00:49.00] magnets are part of the real world, they're science. [00:00:52.04] Let's get reading. [00:00:53.08] Mr. Pack Rat felt so good, he thought he might explode. [00:01:01.01] He had just built his first midden. [00:01:05.00] What's a midden? [00:01:06.09] It's a nest pack rats build out of whatever's lying around. [00:01:12.08] Mr. Pack Rat's midden had a theme, brown. [00:01:17.09] He gathered brown pine needles, brown sticks and leaves, [00:01:22.02] brown acorns, pine cones, and chips of bark. [00:01:25.08] "Brown is such a cozy color," Mr. Pack Rat said, [00:01:30.08] "and my midden is the brownest midden ever." [00:01:36.03] "Whew, I need a break." he said. [00:01:39.04] So he walked to his favorite meadow. [00:01:42.08] The wild flowers were all in bloom. [00:01:47.01] "Oh, these colors!" he gasped. [00:01:50.03] "Juicy reds, perky oranges, and lemony yellows. [00:01:55.02] It's like a rainbow fell from the sky [00:01:58.07] and broke into a million pieces." [00:02:02.06] He thought of his midden, [00:02:04.08] "Argh," he cried. [00:02:06.09] "A one color midden is so boring, [00:02:10.03] only these colors can make me happy." [00:02:13.07] Mr. Pack Rat had an old metal bar [00:02:18.01] that had been in his family a long, long time. [00:02:21.01] The bar didn't look like much, [00:02:23.05] but with the right words it worked like a magnet, [00:02:27.09] a magical magnet. [00:02:31.03] He pointed the bar at the flowers and said, [00:02:34.07] "All these flowers that I see, [00:02:37.07] magnet, bring them home with me. [00:02:40.00] Mr. Pack Rat, Mr. Pack Rat, Mr. Pack rat really wants that." [00:02:46.05] Klinnng! The bar rang like a bell. [00:02:51.03] The magic jumped out [00:02:52.08] and pft, pft, pft plucked every flower. [00:02:58.05] Mr. Pack Rat marched home [00:03:01.01] with the flowers bobbing behind him. [00:03:04.07] Mr. Pack Rat was delighted with his colorful midden [00:03:08.04] for about a week. [00:03:10.02] But then the flowers did what flowers do, [00:03:13.05] they withered and turned brown. [00:03:16.05] Mr. Pack Rat was back to a one color midden [00:03:21.03] and the dead flowers kind of stank. [00:03:25.03] "Eew!" He cried, "I'm going out." [00:03:30.00] He walked to his favorite beach. [00:03:33.02] That day the waves had pushed their most beautiful shells [00:03:38.02] onto the sand. [00:03:40.03] "Such glittering shapes and forms," Mr. Pack Rat gushed. [00:03:46.09] "It's like a million pirates emptied their treasure chest [00:03:51.07] onto the beach, [00:03:53.03] and shells don't wilt." [00:03:57.01] Pointing the bar, he said, "Seashells that the ocean gave, [00:04:03.08] magnet draw them to my cave, [00:04:07.03] Mr. Pack Rat, Mr. Pack Rat, Mr. Pack Rat really wants that. [00:04:13.09] The bar rang, klanngggg! [00:04:17.04] The magic jumped out and rackle, rackle, rackle, [00:04:20.08] scooped up every shell. [00:04:23.07] Mr. Pack Rat strode home, [00:04:26.06] the shells jostled noisily behind him. [00:04:30.03] Mr. Pack Rat was truly happy for a couple of hours. [00:04:35.01] But away from the sun, sand, and sea, [00:04:38.07] the shells didn't dazzle. [00:04:41.08] And what can you do really do with shells anyway? Sort them? [00:04:47.03] "Argh," Mr. Pack Rat shouted, [00:04:50.02] "you shells are so boring, I'm going out." [00:04:56.00] He walked to his favorite store. [00:05:00.00] Everywhere he looked there was something cool. [00:05:04.02] "Toys, and tools, and games," he cried, [00:05:08.01] "telescopes and fishing rods. [00:05:10.02] It's like a million scientists invented [00:05:14.01] every fun thing they could think of. [00:05:16.04] I want it all." [00:05:18.09] The bar was already in his hand. [00:05:22.04] "I have lots, but I want more, [00:05:25.03] magnet, empty every store. [00:05:28.06] Mr. Pack Rat, Mr. Pack Rat, Mr. Pack Rat really wants that." [00:05:35.04] Klongggg! The bar rang very loudly. [00:05:41.07] The magic picked up every item, [00:05:44.03] and schwizz, schwizz, schwizz, [00:05:47.00] threw it at Mr. Pack Rat. [00:05:49.07] This time he had to run home [00:05:51.05] to keep from getting clonked on the head. [00:05:54.02] Mr. Pack Rat's cave was so cluttered [00:05:58.01] that there wasn't room for him to play [00:06:00.00] with his new belongings. [00:06:02.09] There was barely enough room for him. [00:06:05.08] "Eeep!" He squeaked. "I can't breathe." [00:06:09.05] He just managed to squeeze outside. [00:06:13.08] "Stars flared against the jet black sky, [00:06:18.05] infinite space," he cried, [00:06:21.04] "majestic vastness, I want it, I want it, I want it. [00:06:27.00] I don't see a reason why I shouldn't own [00:06:32.00] the whole night sky. [00:06:34.04] Mr. Pack Rat, Mr. Pack Rat, Mr. Pack Rat really wants that." [00:06:41.07] Klungggg! The bar rang like a gong of doom. [00:06:48.06] The magic tugged at every star, moon, and planet. [00:06:55.03] A comet headed straight for Mr. Pack Rat. [00:06:59.09] "No, no, no," he shrieked. [00:07:01.08] "I take it back. I don't want the whole night sky, [00:07:05.08] please, magnet, I take back my wish." [00:07:10.02] The bar leapt out of his hands. [00:07:13.04] When it finally fell, it hit the ground with a thud. [00:07:20.02] Everything was quiet. [00:07:22.07] The moon, stars, and planets sat in their proper places. [00:07:29.08] The comet headed somewhere else. [00:07:33.08] Mr. Pack Rat threw himself on the ground. [00:07:37.01] "I was almost squashed," he wailed. [00:07:41.00] "How did everything go so wrong? I just wanted to be happy." [00:07:46.03] He cried and cried until he finally fell asleep. [00:07:53.02] When Mr. Pack Rat woke up the next morning, [00:07:56.04] the sun was as yellow as fresh butter. [00:08:00.07] Breezes chased each other in the grass. [00:08:04.02] Every leaf wore crystals of morning dew. [00:08:10.00] "Ahhh," said Mr. Pack Rat. He was smiling. [00:08:15.02] He immediately reached for the bar, but then he stopped. [00:08:20.08] "No, no, no Mr. Pack Rat," he said, [00:08:24.02] "what were you going to wish for? The sun? [00:08:27.08] Mr. Pack Rat sat down in a pretty glade. [00:08:32.00] Sunshine warmed his face, [00:08:34.00] breezes tickled his fur, [00:08:35.09] butterflies danced in the air around him. [00:08:39.04] Mr. Pack Rat was happy. [00:08:43.06] He looked at the metal bar, [00:08:46.04] "You know, magnet," he said at last, [00:08:48.05] "I've been using you all wrong. [00:08:50.08] I kept asking you for things to make me happy, [00:08:55.08] but I never knew when I was happy already, [00:08:59.01] and actually I'm quite happy a lot of the time. [00:09:03.05] What I need is a friend to remind me of that." [00:09:08.01] The bar began ringing merrily, klinga-ding, klinga-ding. [00:09:13.04] "What is it magnet? said Mr. Pack Rat. [00:09:16.06] "You sound so hap-" [00:09:19.03] Mr. Pack Rat stopped, then he giggled, [00:09:22.06] "I get it. Klinga-ding." [00:09:27.01] From then on the bar rang, klinga-ding, klinga-ding, [00:09:31.02] whenever Mr. Pack Rat was already happy. [00:09:35.04] Klinga-ding-ding, it rang, [00:09:37.03] when Mr. Pack Rat returned everything to the store [00:09:41.01] and he saw the smile on the shopkeeper's face. [00:09:45.04] Klinga-ding-ding, it rang, [00:09:47.03] when Mr. Pack Rat brought the shells back to the beach [00:09:51.04] and rearranged them on the sand. [00:09:54.05] Klinga-ding, rang the bar, [00:09:56.08] when Mr. Pack Rat spread the dead flowers [00:09:59.09] all over the meadow, [00:10:01.05] the dead flowers would become mulch [00:10:04.06] from which new flowers would spring. [00:10:09.08] And klinga-ding, klinga-ding, rang the bar very softly, [00:10:14.08] when Mr. Pack Rat curled up on his brown midden, [00:10:19.05] ready for a good night's sleep. [00:10:22.06] Mr. Pack Rat, Mr. Pack Rat, Mr. Pack Rat really likes that. [00:10:30.03] (upbeat music) [00:10:34.00] All right, so we're gonna make a mini version [00:10:36.08] of an exhibit that we have here at the Exploratorium [00:10:39.06] called the Strange Attractor. [00:10:41.08] It's a magnet exhibit. [00:10:44.00] And for that, we're gonna need a piece of cardboard. [00:10:46.08] So you want some sturdy cardboard. [00:10:49.00] And I'm gonna use a hot glue dispenser and a glue stick, [00:10:52.08] but you can do this with Scotch tape too. [00:10:56.03] And I have magnets. [00:10:58.05] I have some pretty strong magnets here, [00:11:00.04] but you don't need super strong magnets, [00:11:02.04] you can do this with any magnets that you might have around. [00:11:05.09] I also have one magnet that's a donut shaped, [00:11:09.00] got a hole in the middle, [00:11:10.02] and that's because I'm going to tie [00:11:12.00] a piece of string from it, [00:11:13.08] but you don't need to have one of these, [00:11:15.06] you could just glue or tape a piece of string [00:11:19.00] to the magnet that you have, [00:11:22.04] that doesn't necessarily have a hole in the middle. [00:11:24.05] Okay. [00:11:25.03] So I am going to take my, [00:11:30.01] oh, first of all, what I'm gonna do [00:11:31.07] is I'm gonna mark the north and the south of the magnets. [00:11:35.02] Now you know that opposites attract. [00:11:43.00] So I know that one of these is north, [00:11:47.09] and what it's stuck to is south. [00:11:51.00] So I'm just with a Sharpie marker, [00:11:54.02] I'm just marking one end as north, [00:12:02.07] and the other end as south. [00:12:09.04] I've got four magnets, I'm gonna do five. [00:12:12.03] So one side will be an S and the other side will be an N. [00:12:18.06] All right. [00:12:20.06] Now I have my hot glue dispenser all set up [00:12:24.03] and I'm gonna do these randomly. [00:12:26.01] And I marked these [00:12:28.01] because I don't want the same side of each magnet facing up. [00:12:34.00] And I'm gonna spread them out a little bit. [00:12:35.06] Ooh, that just caught another magnet, glad I marked it. [00:12:40.03] Ooh, they're so strong, okay. [00:12:42.06] So I'm gonna put the south side, the S side, [00:12:46.01] down on the dollop of glue, [00:12:48.09] and I'm gonna do another one kind of next to it. [00:12:53.01] And this time, instead of the south side [00:12:57.01] going down onto the glue, [00:12:58.05] I'm gonna put the N side, the north side, [00:13:01.05] down on the glue. [00:13:03.09] Okay. [00:13:05.07] And another dollop of glue, let me do that here. [00:13:12.09] And again, let me do the N side facing up, [00:13:16.05] so the south side's stuck to the glue. [00:13:19.00] And again, you could do this with tape [00:13:21.07] because magnets are strong enough [00:13:23.01] to even go through cut Scotch tape. [00:13:25.05] And let's do another dollop, say, right there. [00:13:30.02] Ooh, I think I need another stick of hot glue, [00:13:34.07] I won't bother with it right this second, [00:13:38.01] but let's do an N side down. [00:13:42.03] Now, let me get my other glue stick, [00:13:45.07] and another dollop right there, [00:13:50.06] and, oh, it doesn't really matter, [00:13:52.08] let me have the S side down and the N side sticking up. [00:13:56.06] So that's gonna dry a little bit. [00:13:58.09] And in the meantime, [00:14:00.09] because I couldn't draw very well, I used rubber stamps, [00:14:05.08] and I have a rubber stamp of Frankenstein's face, [00:14:09.08] or his head. [00:14:11.03] And so I put those on the rubber stamp, and I cut them out, [00:14:14.08] and I cut two of them out because these are gonna go [00:14:20.02] onto this other magnet that's gonna be hanging. [00:14:23.07] I also had a rubber stamp of a box of Froot Loops cereal. [00:14:30.05] Or you could draw a bird, or a butterfly, or something, [00:14:33.07] but you want to draw it twice [00:14:35.07] so that you can glue or tape one picture, [00:14:40.01] the one side of the magnet, [00:14:42.01] and then the other to the other side of the magnet. [00:14:44.01] Now, I am going to tie a piece of string onto this magnet, [00:14:50.00] remember I have a hole in the middle of it, [00:14:52.05] and I'm gonna try the tie it quickly and securely. [00:14:56.08] So let me do a double knot. [00:15:01.01] Okay. [00:15:05.02] So that is pretty secure. [00:15:08.01] Again, if you don't have a hot glue dispenser, [00:15:12.09] and a hot glue stick, or a magnet with a hole in it, [00:15:15.07] you can just do this with Scotch tape. [00:15:18.05] Regular glue kind of takes too long to dry. [00:15:22.05] All right, and now I'm going to put some hot glue [00:15:28.02] on one side of this magnet, [00:15:35.09] and I'm going to stick Frankenstein's face on there, [00:15:41.08] making sure not to burn myself. [00:15:45.03] So, whoops, [00:15:47.05] here we have Frankenstein's face on one side of that magnet, [00:15:52.04] and now I'll do Frankenstein's face [00:15:55.00] on the other side of the magnet. [00:15:56.07] We'll do the glue. [00:15:58.00] Again, you may want an adult assistant [00:16:01.05] because grown ups are really good to have around [00:16:05.04] to do some of those things that might be a little bit scary, [00:16:08.06] like using hot glue. [00:16:11.06] All right, and there goes Frankie's face on the other side. [00:16:17.02] All right, so now there's double faced Frankenstein. [00:16:23.09] So now I'm gonna turn this upside down [00:16:26.02] so that you don't see the magnets, [00:16:28.01] and I'm just going to hold this above, [00:16:33.03] and move him around a little bit. [00:16:34.06] Ooh, it's like the haunted head of Frankenstein. [00:16:41.07] If you put a ton of magnets on the underside, [00:16:45.07] that would do this even more. [00:16:47.06] But this is what's happening. [00:16:50.04] This magnet that's on the string [00:16:53.06] is either being pulled by, [00:16:56.05] or pushed away from the different magnets [00:17:01.03] because some are facing north, and some are facing south, [00:17:04.04] some are facing positive, some are facing negative. [00:17:08.05] And that's just like a Strange Attractor [00:17:10.06] here at the Exploratorium, [00:17:12.06] and by the way, we're open again. [00:17:15.01] So you can go online and buy tickets, [00:17:17.08] or come on down to the Exploratorium [00:17:19.07] and experience it firsthand. [00:17:22.03] And like I said, [00:17:23.03] if you did a bunch of magnets on the underside, [00:17:27.08] there would be even more motion [00:17:30.05] for a haunted Frankenstein head. [00:17:33.04] If I had done the box of Froot Loops, [00:17:35.08] it would be the haunted box of cereal. [00:17:38.05] (upbeat music) [00:17:42.08] Time for Poetry Corner. [00:17:45.07] All right, I wrote some poems, [00:17:47.06] once again, I wrote three magnet haikus, [00:17:51.06] and then I wrote a longer magnet poem. [00:17:55.00] So remember haikus are counting poems. [00:17:58.08] The first line has five sounds, [00:18:02.00] the second line has seven sounds, [00:18:04.08] the third line again has five sounds. [00:18:08.03] Here are my magnet haikus. [00:18:11.08] North pole and south pole, [00:18:14.06] the earth is a big magnet, [00:18:17.02] compass, do your thing. [00:18:21.04] Opposites attract, [00:18:23.05] south to north and north to south, [00:18:26.05] it's a proven fact. [00:18:30.03] Batteries have ends, [00:18:33.06] positive and negative, [00:18:36.06] so a charge can flow. [00:18:42.00] All right, now onto the poem that I wrote, [00:18:45.04] that's called "What If People Were More Like Magnets?" [00:18:52.00] Let us pretend we're magnets, [00:18:54.06] and then we just might see the ones we think are different, [00:19:00.06] our friends who are meant to be. [00:19:03.09] Like north and south, or black and white, [00:19:07.06] will never be the same, [00:19:09.07] the languages we speak at home, [00:19:12.04] the foods with different names, [00:19:15.05] the holidays we celebrate, [00:19:18.00] the music that we listen to, [00:19:20.07] we seem to be so opposite in everything we are and do, [00:19:27.00] but differences are awesome things. [00:19:30.04] A welcome hand I will extend, [00:19:33.08] I'll be more like a magnet to my newest bestest friend. [00:19:39.06] (upbeat music) [00:19:42.01]
