  • STEVE SPANGLER: Welcome to Toy Fair 2012.

  • So look at this.

  • God, that's amazing.

  • Oh, and it doesn't take much of a squeeze at all.

  • You are now compressing some of the air

  • that's in that packet.

  • So I bet you think this is the part of the show where I'm

  • going to say, don't try these experiments at home.

  • And you're right, except there is one experiment

  • we want you to try.

  • Just look for the graphic that's right here

  • that says try it.

  • That's your signal that you can try that

  • experiment at home.

  • Everything else off limits.

  • Look, I've already given you homework, and the show hasn't

  • even started.

  • I'm Steve Spangler, and I'm all about making science fun.

  • For the last 20 years, I've been teaching ways to turn

  • ordinary science experiments into unforgettable learning

  • experiences.

  • I have an amazing team who will do whatever it takes to

  • affect the way people think about science.

  • And to do that, I live by one motto--

  • "Make it big, do it right, give

  • it class." All right.

  • Watch this.

  • There's a squid in the bottle--

  • seriously.

  • And you just take a hair like this-- it's a trained squid--

  • and you wrap the hair around the squid.

  • It's almost like a lasso.

  • Hard to see.

  • See I can kind of pull the little--

  • here let him go.

  • Just grab the hair, pull him down like this.

  • And you can take him to the bottom and just pull the hair

  • off, and he'll go right back up to the top, and--

  • OK, that's not how it works.

  • But it's the first science toy I ever invented.

  • And some people will ask, so how does a science teacher own

  • a toy company?

  • And the reason why is because of that dumb squid in a bottle

  • that goes up and down when you actually squeeze the bottle.

  • This is it.

  • It's the very, very first toy that started the toy company.

  • And it's nothing more than an eye dropper and a hex nut and

  • this little rubber piece that's the squid.

  • And let me show you how easy it is to make the diver.

  • Well, here are the pieces, parts that we're using today.

  • I've got just some 1 liter bottles filled with water, a

  • couple of deep containers, because we're going to need to

  • do some things that sink and float.

  • The original Cartesian diver, named after

  • Rene Descartes, used--

  • well, the original one, I'm sure used something other than

  • glass eye droppers.

  • The oldest one I can remember used a glass eye dropper.

  • And today, you can still find them at stores like Walmart or

  • wherever, a pharmacy.

  • Let me show you how to do it with the original one.

  • The whole idea is this.

  • You have to get a container of water like this here, and you

  • drop the eye dropper inside.

  • And you say float or sink, and, of course, it floats.

  • And it floats because there's air inside that eye dropper.

  • Even though it's a glass eye dropper, there's air.

  • If I hold it up like this-- here, take a look at this--

  • I can squeeze some of the bubbles out like this, and

  • pull some water in.

  • So in essence, I'm changing the mass, right?

  • And now it just barely bobs there.

  • See how it bobs up and down that way?

  • OK, so that's perfect.

  • When you make a Cartesian diver, you've got to have that

  • kind of set up there, so it just barely bounces around.

  • Now we've got a 1 liter bottle.

  • And I'm using a 1 liter.

  • You could use a 2 liter.

  • It's just easier to squeeze with a 1 liter.

  • Remove the label.

  • It's almost full to the top.

  • And one of the secrets of a Cartesian diver, to make it

  • easier to squeeze, anyway, is to make sure there's just no

  • air inside the bottle.

  • The only air that we want--

  • if you take a look at this right here-- the only air that

  • you want is the air that's in that Cartesian diver.

  • All right.

  • So now, here's what happens.

  • You take a cap and put the cap on like this.

  • And now, we're ready to go.

  • So the way it floats and it sinks is if I can change the

  • mass, ultimately changing the density-- if I can change the

  • mass, because the volume is going to stay the same, then

  • density equals mass divided by volume.

  • I know it's nerd fest here, but I've just got to change

  • the density so it's greater than 1 and so it will sink.

  • So watch-- as I squeeze it, you can actually see the water

  • level going up.

  • You see this here?

  • So I'm just barely squeezing it.

  • So water's being pushed up into here.

  • The air compresses, because the water cannot compress.

  • And when it gets heavy enough, it finally sinks.

  • Isn't that nice?

  • And as you let go, it will float.

  • So we've got a perfect way to be able to make something

  • float or sink.

  • And of course, we're just using our fingers to be able

  • to squeeze it.

  • You can do all the magic that you want to.

  • You pretend like you have the magnetic finger.

  • And when the person comes up, their finger follows.

  • And if you just don't want the person to have the magnetic

  • finger, then you just don't let them make it work, right?

  • But that's the classic Cartesian diver.

  • I was introduced to a new style of Cartesian diver by a

  • man by the name of Bob Becker.

  • Bob is a chemistry teacher in Kirkwood, Missouri, and

  • actually showed me this version using plastic eye

  • droppers called pipettes.

  • And they're very, very prevalent in

  • the chemistry classroom.

  • A lot of teachers use these pipettes.

  • They may be a little bit harder for just the average

  • person to get their hands on, but just befriend a teacher,

  • and for sure they know about pipettes.

  • This one is special, because it's graduated.

  • Do you see this one here?

  • And when you're picking one, just make sure that you can

  • find one that the hex nut will go over the top.

  • So if I drop this into the water like this-- so here's

  • our container.

  • Let me drop this into the water.

  • Of course it floats, right?

  • I want to weight it down.

  • So here's what we're going to do.

  • We're taking a regular quarter-inch hex nut.

  • And I use these brass ones, because they don't rust.

  • This goes on the pipette like that.

  • So here's what it looks like.

  • It's just right there on the pipette.

  • And then I'm going to twist and turn it into place like

  • this, so it kind of holds it into place.

  • And that's what it looks like.

  • It's held into place.

  • A pair of scissors will help us cut the end off.

  • And now we have the makings of a modern-day Cartesian diver.

  • So the same thing-- of course it floats.

  • So watch.

  • When we drop it inside, it floats.

  • If I squeeze some of the air out and pull some of the water

  • in, I can make it so it just barely floats.

  • Of course, of we have too much water in altogether, then the

  • whole thing will sink.

  • So I want it so it just barely floats.

  • So I'm going to just continue to play with it.

  • That seems to be a pretty good buoyancy there.

  • Again, that whole idea is so it just barely floats.

  • So now that we have it adjusted, you just have to be

  • careful that you don't get any of the water out.

  • It goes down inside.

  • Notice how it's full almost to the very, very top.

  • That's exactly what we want--

  • no air inside the bottle.

  • And now we cap it off.

  • Again, just as it happened before, that we saw with the

  • glass eye dropper, when you squeeze, notice how the water

  • goes up inside.

  • This systems just works perfectly.

  • Bob's a genius.

  • And there is the making of the modern day Cartesian diver.

  • We had to find a way to disguise

  • this diver right here.

  • I was working in television in the early 1990s for a program

  • called News for Kids.

  • And so on the set, we had a whole bunch of kids.

  • And they were squeezing this.

  • And the director kept on commenting that she couldn't

  • see the diver very well inside.

  • So we found other ways to be able to glue things on, for

  • example, or use a Sharpie pen to color on them.

  • Again, Bob Becker had a bunch of great ideas.

  • But I wanted something that was just a little

  • bit easier to see.

  • So I'll show you how we changed everything.

  • It looks like a fishing lure.

  • It's not really a fishing lure that would catch a fish.

  • These were specially made, because the regular fishing

  • lure just wouldn't go over the pipette.

  • Remember coming back and trying to find a way to be

  • able to use this and put it over the pipette.

  • So here, watch.

  • This is Squiddy.

  • So you just open up the little opening here like this.

  • And then this slides over the workings of

  • the squid like this.

  • And this is the new squid.

  • All right, so this is in place.

  • Enough history.

  • As you squeeze, the water goes inside, the little squid falls

  • down, and as you let go, the squid goes up again.

  • And that was Squiddy.

  • So let's say you don't have a squid and you don't have

  • pipettes and hex nuts and everything else and you'd like

  • to do the Cartesian diver.

  • I'm going to show you how to do one.

  • This is ingenious.

  • It's done out of a condiment.

  • It's just ketchup.

  • So you're going to start collecting

  • some ketchup packets.

  • This is an interesting Cartesian diver.

  • And it's interesting because, in this style of Cartesian

  • diver, there was an open end.

  • So when you squeeze, water would go inside.

  • You would increase the mass, and it would sink.

  • But when you use something like this, these ketchup

  • packets have never been opened.

  • And so this means that the mass has to stay the same.

  • We would have to possibly change the volume if you want

  • to change the density.

  • So here's what you need to do.

  • Not all ketchup packets work.

  • Collect a whole bunch of different ketchup packets and

  • in a container of water, just drop them inside.

  • Some will float, and some will sink.

  • You're hoping that a couple will float.

  • And pick the ones that will float.

  • OK, so this is a good one here.

  • This one may float just a little too much.

  • And this one right over here, this Carl's Jr. one might do

  • fairly well.

  • So you want the two of them that just barely float.

  • All right?

  • The other ones are out of the question.

  • So again, here's our bottle.

  • Let's try that Carl's Jr. one.

  • Let's see if this one works fairly well.

  • So you're going to take the ketchup packet.

  • Don't open it up.

  • Just kind of fold it and push it down into the bottle.

  • And you're going to lose some water, so you're going to have

  • to fill it back up again.

  • Ah, so there it is.

  • Bingo.

  • Got it.

  • And now, cap it or top if off this way.

  • And we need a cap.

  • So this will go on the top.

  • So now, look at what we have.

  • This is fairly cool, because this now doesn't get ruined if

  • you turn it upside down or anything like that.

  • It just kind of sits in here.

  • While you can't see it, as you squeeze--

  • and it doesn't take much of a squeeze at all--

  • you're now compressing some of the air that's in that packet

  • and changing the density or the buoyancy.

  • And that's the simplest of the Cartesian divers.

  • Now that you know how Squiddy works-- a simple science toy--

  • there's a big jump from having an idea like this to actually

  • getting it into stores.

  • And the best way to do that is a convention called the New

  • York Toy Fair.

  • It attracts thousands and thousands of people.

  • These are people who own educational stores, regular

  • toy stores.

  • And that's the best way to be able to show people.

  • Well, the product line has grown from just a couple

  • products that we started with the 1993 to now over 75

  • products in a company called Be Amazing!

  • Toys.

  • So I want to give you a behind the scenes glimpse of what Toy

  • Fair looks like-- the normal public isn't allowed in-- and

  • what happens when you walk the aisles and ask other people to

  • show you some of their best toys, as well.

  • Take a look.

  • Well, it's cold for a reason.

  • It's February in New York.

  • It can only mean one thing--

  • Toy Fair.

  • And we'd like to have you help us out a little bit.

  • So we want to comment below and tell us which toys we're

  • going to show you are the great ones and which ones are

  • kind of-- eh.

  • Well, you be the judge.

  • And welcome to Toy Fair 2012.

  • All right.

  • This is a sneak peak of Toy Fair.

  • We're actually in the exhibit hall, because we're exhibitors

  • today with Be Amazing!

  • Toys.

  • It's wonderful company they carries so many of the Steve

  • Spangler science items.

  • But they carry it for things like Target and Walmart and

  • mass-market stores in addition to small ma and pa stores.

  • Those brick and mortar stores are there as well.

  • And this is where I get to hang out for

  • the next eight hours.

  • And I have a feeling-- see these hands?

  • They are going to be coke-covered here in no time,

  • because it's my job to launch as many geysers as I can.

  • I have 780 bottles to get through.

  • And it'll be a successful day if I get it.

  • See ya.

  • Now, when I pull the pin, the Mentos will fall, just like

  • the model here, right?

  • The secret is that those little pits on the outside of

  • the Mentos, all the carbon dioxide rushes to that--

  • they're called nucleation points-- and it

  • shoots the soda out.

  • We're just going to turn it sideways, see if Isaac Newton

  • was correct.

  • And if he was, we get a little shot.

  • All right?

  • So this goes in here like this.

  • All right, normally you're outside or you're sneaking in

  • some place that has great floors like Home Depot.

  • You'd shoot it all past plumbing and down the--

  • don't do that.

  • This pulls like this when it falls.

  • It starts to flow.

  • And as you let go, bam!

  • Isn't that a good shot?

  • That was.

  • It'll go about 150 feet at about 30 miles an hour with

  • what you saw there.

  • Now that we're done at the booth, let's go check out some

  • of the cool toys at Toy Fair.

  • Who doesn't like a severed hand that runs around on a

  • wall and scares the crap out of kids?

  • That's perfect.

  • You know, of anybody doing science kits today, Thames &

  • Kosmos has got to be one of my favorites and one of the best.

  • You look at this-- they're doing real science.

  • The materials that you see here are not watered down.

  • So if you're looking for chemistry along the way, this

  • Thames & Kosmos place is great.

  • MALE SPEAKER: Straw with flavored beads in the middle.

  • STEVE SPANGLER: Lobster?

  • Is it lobster?

  • MALE SPEAKER: That's it.

  • STEVE SPANGLER: Shrimp?

  • MALE SPEAKER: Taste it again.

  • Maybe let the beads dissolve a little bit more.

  • You're not quite getting the flavor.

  • Now what do you think?

  • STEVE SPANGLER: Strawberry.

  • MALE SPEAKER: Strawberry, you got it.

  • STEVE SPANGLER: Strawberry lobster.

  • It actually tastes like strawberry lobster and shrimp.

  • Well, we're at Insect Lore.

  • These are people that I've known for years

  • and years and years.

  • And there, they manufacture this wonderful thing called

  • the butterfly pavilion.

  • And so I would stand in their booth years ago and tell

  • people that the butterflies were good to eat, and they

  • were just raising them for salads.

  • And a lot of people would believe that.

  • And then I got kicked out.

  • Do not eat the butterflies.

  • I thought it was just all about buying bugs.

  • And now it's a campfire.

  • MALE SPEAKER: Now it's all about camping.

  • STEVE SPANGLER: OK, go away.

  • I need to get in the camp.

  • MALE SPEAKER: It's time for bed.

  • STEVE SPANGLER: All right, so here's kind of a you choose it

  • an adventure.

  • You can choose what you want me to do.

  • I'll either A, go sneak into the tent at Insect Lore and

  • sleep there for the night, or B, I'll pretend like I'm a

  • sales person, and I'll sell butterflies, but convince

  • people that they're not real and they're animatronics.

  • All right, well, 3D is all the rage.

  • And these are 3D glasses here from Look3D.

  • And not only are they 3D glasses, they make you look

  • really sexy.

  • And watch this, I can look--

  • oh my god.

  • See that?

  • All contained in these classes here.

  • No batteries at all.

  • How many pounds?

  • MALE SPEAKER: This is 25 pounds.

  • STEVE SPANGLER: All right.

  • 25 pounds of Aaron's Thinking Putty.

  • It changes color.

  • This is a tremendous amount of fun.

  • I don't think he was a problem in school at all.

  • This is just what he does.

  • MALE SPEAKER: We're going to turn that

  • nice lady into a butterfly.

  • STEVE SPANGLER: All right, let's go see the butterfly.

  • How cool is that?

  • MALE SPEAKER: [INAUDIBLE].

  • STEVE SPANGLER: That is awesome and tasty too.

  • Tastes like that lobster stuff that I had at the other booth.

  • Look at this.

  • MALE SPEAKER: When you spread out your fingers, they weave

  • in and out.

  • Here, we'll show them his nose.

  • Oh, he's scared.

  • Put it on your shower door, it turns your whole

  • shower into a speaker.

  • STEVE SPANGLER: You're using the entire box to just

  • resonate the sound.

  • Here's a booth--

  • four million different kinds of dice.

  • So here's the deal.

  • This nice man right here said that I can go sneak a toy away

  • during a live shot.

  • So they wrote something like "Hello, Denver" or something.

  • But during the live shot, we'll go sneak it away and

  • just see how he reacts.

  • He's good.

  • So he'll react well.

  • CHRIS BYRNE: And you know who's running around here?

  • Steve Spangler's running around Toy Fair creating all

  • kinds of havoc.

  • And I-- wait, there he is.

  • STEVE SPANGLER: I'm taking this back to the station.

  • CHRIS BYRNE: He's taking it back to the station.

  • So we are having so much fun here at the American

  • International Toy Fair.

  • So great to see you.

  • STEVE SPANGLER: You too.

  • There's the regular--

  • there's six things on a die.

  • And then there's this one that's red.

  • And this one, it's another die, which looks a lot like

  • this one, but it's completely called the swirl die.

  • And this is the gator die and the pearl die.

  • This would be the cow die, the dog die, and the woodland

  • animal die--

  • not to be confused with the bison die, the beetle die, the

  • scorpion die, and the ladybug die.

  • One of my favorites--

  • the bat die.

  • There's the sided die-- the 16-sided die.

  • There's the hip dice, Chinese dice, Amish dice, regular

  • dice, Japanese dice, and another alien dice which is

  • probably a knock-off of that alien dice over there.

  • There's spotted, spotted, spotted, counting.

  • There's loaded dice, just in case you have a craps game and

  • you want to win--

  • loaded dice.

  • Nothing says I love you more, kids, than to give you a bowl

  • of dice for your birthday.

  • Happy birthday.

  • Here's a bowl of dice.

  • My all time favorite-- you can vote on it down below--

  • opaque die.

  • One question we never get to ask-- what do you think about

  • alligators?

  • And do you have any thoughts on the current debate over

  • endoplasmic reticulum?

  • MALE SPEAKER: I'll show you just a quick trick here.

  • You've got a ring now, right?

  • STEVE SPANGLER: Right.

  • MALE SPEAKER: If I squeeze them together,

  • now I've got a triangle.

  • If I fold up the tips, I've got an octahedron.

  • I can put it back down and smash it and it goes right

  • back into a ring.

  • STEVE SPANGLER: Nice.

  • MALE SPEAKER: Now, pinch here, fold it over, and I've got

  • myself a spinning top.

  • And if I add two, I get eight.

  • Eight's a cool number.

  • I known to be two times two times two, or two cubed.

  • Just like that.

  • Now, I'll show you a really cool trick.

  • It requires 12.

  • So I'm going to add four more here.

  • And 12's a really interesting number, because it allows me

  • to just wrap them around my fingers twice.

  • STEVE SPANGLER: Right.

  • MALE SPEAKER: Pinch here, and I pull these two to the side.

  • Now I've got myself a ball.

  • STEVE SPANGLER: God, that's amazing.

  • [STEVE, POORLY, PLAYING "CLOSE TO YOU" ON UKELELE]

  • STEVE SPANGLER: It's out of tune.
