No one has tested our insurance policies more than this guy.
He's Steve Spangler, everybody.
[MUSIC PLAYING]
Thank you, thank you, thank you.
Host of "DIY Sci."
I have things in front of me but I don't
think I'm going to do them.
So what are we doing today?
No, you are.
In fact, since this quarantine I've
been putting so much stuff online.
Teachers have got to teach, parents have become teachers.
And so we're still trying to do science.
So I found this little thing in May.
I had zero followers, zero videos on TikTok.
We just tried it and it exploded.
So I brought you my favorite TikTok demos.
All right.
Fair enough?
Yeah.
So it's like a duet.
OK.
All right, so you're drinking your morning coffee.
OK, so just take the water and--
it's vodka.
Just pour it in.
Yep, OK.
Just-- there you go.
All right.
About half full.
Yeah, good.
Oh, well you didn't say that.
That's OK.
Yeah that's good.
All right there.
And then let's say that you add some sugar and some cream.
Then you'd have to take a spoon and stir it.
That's a lot of work.
It sure is.
So that's why you need to carry around this board
wherever you go.
So you see the board?
Uh-huh.
OK.
So now just take the cup, and you set it right here
in the middle of the board.
Right.
[CHUCKLES] And now-- like get it in the middle.
Get it in the middle, good.
OK, good.
Yeah, it's good.
OK so now, just kind of pick it up like this
and meet me out front.
Come on out front.
Like this, oh yeah that's perfect.
So now instead of a spoon, we're just
going to use centripetal force.
So you're right handed?
You're right handed?
Yes I am.
So hold it with your right hand.
So now here's what you're going to do.
You're just going to kind of swing it back and forth
to mix the coffee.
There you go.
And then, to really get it mixed, a little up and over.
Hey-o, come on you can do it.
Yeah, yes!
Wow.
Yes, very, very nice.
Look at that, if you're feeling good.
Look at that, look at that, look at that.
Around here like this, wah.
OK, hold on, hold on.
OK, no, no, no, no no.
Oh gosh, that was amazing how you did that.
You told me to.
Holy moly, wow.
OK, well you've mixed the coffee.
Take a bow, you did a great job, ta-da.
Uh-huh.
OK, back to your station.
All right.
Back to your station.
Wow, you scared me there, I didn't think--
All right, so come on over here to the cups.
You see your cups are right there?
We asked the entire studio audience
if they would get their solo cups.
So if you'll get your solo cups, that would be great.
So this is a TikTok favorite, here's what happens.
You take the 1 cup and put it inside the other cup like this.
And then the third cup you hold with your other hand.
So you have two in one hand, one in the other hand.
Here's the object, is you've got to get this cup here
to fly up in the air and go over into this cup.
And you can't do that.
You're going to use your breath.
So you blow fast moving air at the cup.
The darn thing will pick up here, fly through the air
and land in this cup.
Watch this, ready?
[BLOWS AIR] Ta-da, look at that.
Try it, try it.
Thanks.
Thank you-- Go, you ready?
Go.
Yes that's it.
Yes, go, go.
You ready?
Go.
Oh, there's another one for you, Ellen.
Just [BLOWS AIR].
Look at that, fast moving air, we--
[BLOWING AIR]
Yeah, look at the studio audience is doing it.
[BLOWING AIR]
Oh yes.
No, no, Ellen, you did--
No, no, no, no.
Oh my gosh she's scary.
Just going to go back-- no.
I've just had a lot of time to [BLOWS AIR]
to do this forever, so.
Yeah.
Nice job you guys.
Bernoulli's principle, he would be so proud.
Fast moving air creates--
[SOLO CUPS FALLING]
All right, all right.
You know how you love magic?
Oh I do.
Watch this, ready?
Like a magician, ready?
Pick up the Mason jar, show it to the audience, nice.
And now take the water, good.
And now pour the water into the Mason jar like this,
with a little flourish.
Nice.
Yes that's good, keep going, good, good, good.
Yeah keep going, keep going, keep going.
Now show everybody the instruction card, nice job.
Put the card on top, all right.
Now this is a-- you've got to hold the bottom here like this.
Put your finger on top.
Good, now watch this.
Turn the whole thing upside down.
[CHUCKLES] OK hold it up, be brave.
OK so now watch this.
If you slowly take your finger away, watch
the card will stay there.
Try it, so turn it upside down.
Good, now slowly pull your finger away.
Look at that.
Hold it a beat.
Now watch this, ready Ellen?
Take that card and pull it away.
Yes, would you look at that?
It's because of magic powers, ladies and gentlemen.
Now watch this, ready?
Just tip it like this and it will all pour out.
Wow.
Take your bow, thank you very much.
Thank you.
Let's show them the secret, ready?
I'm going to show them the secret.
Show everybody, there's actually a screen in here like this.
So you just go to your in-laws home
and you cut a piece of screen and you put it in the jar
like this.
And then, watch this, Ellen.
When you put it in like this, the water
hooks together like this.
So adhesion and cohesion holds it in place,
and it stays there.
So when you pull it away air pressure was holding it.
It's adhesion and cohesion.
Adhesion and cohesion, those are my nephews names.
All right, wow.
Big finale.
That's amazing.
You ready?
Watch this.
OK, pick up the glass that has the water.
And show everybody the red cup.
So now watch, do as I do.
You've got to promise.
Say, I'll do it.
I'll do it.
All right, so pour the water in quickly like this.
Got it?
And now wave your hand over the top.
Bam, over your head.
Do it!
No.
Come on, do it!
No, no!
Trust me, trust me, go.
Ready?
And the crowd goes wild.
Now shake it out.
Ready?
Shake it out.
Remember these are all things that you can do at home.
So look-- look at this, it's turned to a solid.
It was a liquid, it was a solid.
It's slightly toxic to touch but-- no it's not, it's fine.
Look, it's this.
It's this super absorbent polymer
that it's in a baby's diaper.
That's the secret.
So I'm sorry that I didn't tell you that ahead of time.
So show everybody the clear cup again.
Yep.
So try this one.
No try the new one that's up top.
Yep, yep.
And take your water and show them how quickly it happens.
All right.
So this super absorbent polymer absorbs the water.
3, 2, 1, snap your finger and--
[INHALES SHARPLY] it stays there.
Wow.
Would you look at this, it's that fast.
All favorites from TikTok.
Wow, incredible, Steve.
All right, we're taking a break.
One more, after this.
Thank you.
One more.
We are back with the host of "DIY Sci," science guy, Steve
Spangler.
And now what are we doing?
Well it was 15 years ago that we first did this on YouTube,
dropping Mentos into Diet Coke.
It was a great way to teach people about carbonation.
So if you shake up a soda-- remember I showed you that?
If you shake up a soda and it goes all over the place,
unless you tap the can.
Well come to find out, if you take Mentos and you drop them
in, there's little imperfections in these Mentos
and all the carbon dioxide runs to them.
Not a bad idea.
So I'll just show you here is the original experiment.
So you just would takes some Mentos
and then you'd try to drop them in like this.
And then you'd try to get them in there as fast as you could.
The problem is, see how you can't get them in too fast?
So I wanted them to go higher.
And it was hard to get them in like this.
And it was a-- ugh.
So I invented this toy.
It's called a Geyser Tube.
And you just you put the Mentos in here and then when you pull,
then they all drop at once.
So instead of me doing this silly thing,
I made those for you, see?
So if you just reach over--
I am normally with you but I can't, so-- because we
have to be socially distanced.
So if you put your thumb there and just pull one,
watch what happens.
Just one.
Yeah it's fun.
All right.
All right so-- see, there you go.
Oh, see?
Good, now pull that one over there.
Pull the middle one.
You're-- at the other end, yeah.
That's good and the next one, fast.
Ready, go, and go.
Yes see.
Now, not bad, not bad, not bad.
Now, the fun part is that if you restrict the opening,
like this, it sprays out.
How fun would that be?
It'd be fun.
Yeah, so open the door and I'll show you,
I came up with a little something for you.
OK.
So, so do you remember the last time I was on?
Andy accidentally fell down, Ellen.
Do you remember that?
Yes, I do.
So you're going to make it up for him?
Well I just wanted to give him a front row seat.
Come here, you're going to help me with this.
So here's what we have.
We have all the bottles of the diet soda in here.
They're all loaded with Mentos and there's magnets.
So when we pull like this, Andy you get a front row seat.
OK.
You're kind of like on "Toy Story," Andy in the box.
OK, so if I pull here like this.
OK.
And Ellen pulls.
Then those are going to fall and you-- you shouldn't get wet.
It should be fine.
So it's just sideways?
Yeah, no you're fine.
They're aimed perfectly so you shouldn't get wet.
I'm going to put this on.
So here, you ready, Ellen?
OK.
See this one over here?
So we're just doing this one?
Want to give me a warning?
When I say this one here, just pull all the way.
Ready, 3, 2, 1, pull.
That's good, so you see-- oh yeah, so you got it, see?
Oh.
It looks great.
Oh that's cold.
Here let's do these at the front.
Ready, set, go and pull this one here, good.
And pull this one here, Ellen.
Grab, them again.
See?
You look good, Andy.
Oh my God, stop!
So cold.
You got a front row seat, Andy.
Oh my God, thank you.
Thank you.
Oh my God, Andy.
I think they were aimed maybe a little wrong, but--
Oh my God, that is horrible we did that to you.
I can't hear you.
Just do something.
