– Dah, oh! – It worked! – This is scary, guys.
Don’t try this at home. ♪ (upbeat intro) ♪ – (FBE) How do you feel
about science experiments? – Um, I’m excited!
– I love science experiments! – (FBE) So today, we’ll be giving you
everything you need to complete several
science experiments. However, we won’t be
giving you any instructions. – No way.
– Oh no! – That’s so sick! – (FBE) If you can explain to us
what you’re supposed to do to trigger a chemical reaction,
you’ll get a point. If not, we’ll give you some help, and if you can then complete
the experiment correctly, you’ll be able to get another point. – Okay.
– Alright. – Okay, yeah.
– Yeah. – Let’s do it.
– I feel like we’re gonna blow something up on accident anyways
by like mixing the wrong chemicals. – I think if we like
went to school together, and we were assigned
a project together, we’re your last two brain cells,
you know? We’re gonna get it done.
– I probably wouldn’t have been there. I probably would copy off him. – (FBE) We’re going to start you off
with the easiest one. Do you know how to do
this viral challenge? – I’ve done this before. – I haven’t done this.
– You haven’t done it? – I’ve just, I’ve seen it done before. – I think we just put in the Mentos
and shake it. – (laughs) You don’t shake it. I know from experience. – You don’t shake it?
– You don’t shake it. – I don’t know why
the index card is there. – Do you put it like here?
[Bleep]. (laughs) – I don’t know, do we have
to use all of it? – (FBE) Mm-hmm.
– So we have to use the index card. – I’m guessing you have to
use the card to stop the Mentos, and then pull it
out at the right time. – Oh! – Flip this over.
– Open this vial, flip it over,
remove card. – You do this, basically. And then we just
let it rip. – Do this, and go pah! Ope!
– Oh, I’ll hold it. – Not that. – (FBE) So you guys
got this one right! – Yeah!
Let’s go! Thanks Jordan!
(laughs) – (FBE) Let’s do the experiment. – Alright.
I’ll open this one. – Cool.
That’s step one, and then… – Ooh!
– Step two. Okay, I’ll let you do the honors
of pulling the notecard out. One, two, three, go.
– (Ary) Ooh! (bell rings) – (Brandon) Yeah baby!
– (Ary) Oh my God! – Okay, ready?
– Yeah. (Izzy yells)
(Jordan screams) (bell rings) – (Izzy) Yeah!
– (Jordan) Woo! (bell rings) – (Chelsea) Whoa!
– (Noah) That’s so sick! – (Chelsea) Yeah, this is so cool! It’s so satisfying to watch, too. – Three, two, one. – (Michelle) You’re an idiot!
– (Carson) No, no, no! – (Michelle) Get it in there!
– Just get in there, just get in there.
Hold on, oh gosh! – One of us should have
held the bottle down. – Oh, so yeah! – That was your job. – No yeah.
– I blame Carson. – Yeah, I’ll take it.
I’ll take the heat on this one. (whispers) No, it’s her fault. – I think we did it, I think.
– I think so. – I think, this is an A,
would we have gotten an A? – (FBE) Yeah.
– An A, see? – Perfect, yes. – (FBE) We’ve given everything
you need to make a rainbow volcano. (both gasp)
– (Izzy) Ooh! – (FBE) But can you figure out
how to make the colorful explosion? – (Jordan) Oh my gosh. – That’s great.
– (FBE) Tell us the steps you think. – I don’t know!
– So we got foil. I feel like these have to combine. – The baking soda in first,
then the vinegar? – I’m gonna assume you put
the vinegar in the baking soda, and not the other way around, ’cause that doesn’t make sense. So what is the aluminum
and the cup for? – Foil and the cup. This could be just for
aesthetic purposes. – So this could be our volcano. – Right.
– And we could just cover it. – Oh, we could pour
baking soda in here. – Yeah.
– Wrap it, and then pour…
– Yeah. – (FBE) That’s essentially
what you do. – Aw [bleep]!
– (FBE) I’m gonna give you this point. – We did it, alright, alright!
– (FBE) Make your volcano. – After you.
– Let’s make this. – I’m just gonna take a nice little scoop
of baking soda there. – You’re doing great!
– Just gonna, you know what? Volcanoes are not perfect. – Professional science
engineer here. – They’re gonna use this
for the science videos for elementary school,
hope you know that. – Poke a hole, there we are. Good stuff, great stuff. This is mount Brary. Now we’re gonna add
the food coloring. – To the vinegar?
– Yeah. – Do you wanna grab the other two? Ooh.
– (Brandon) Ooh, that’s cool! – (Ary) Grab the other two.
– Okay, okay, okay. – Okay.
– Let’s explode, explode! Yay!
(bell rings) That was way more satisfying
than the Coke. – (Noah) That was very,
that was satisfying. – Voila!
– (Michelle) Too much, my guy! – What, it’s not too much.
Wait, wait. And the colors, there it is,
you got one, there we go. – Ya saw nothing.
– Fantastic! – You saw nothing.
– You saw nothing. – Yes, I have all of ’em. – Where is the other ones?
Okay, here we go, woo! – Science. Whoa, that’s gross!
I love it, more. Oh! – (Ary) Pretty. – This is Mount Brary’s
first eruption. Wow, that’s really ugly. – Dah, oh!
– (both) Whoa! – It smells bad,
but it looks so cute! That was fun.
– We did great! – That was a volcano, dude!
Thanks, friend! – (FBE) Now we’ve given you
what you need to melt this head
like the Wicked Witch of the West. So what do you think you do? – (sighs) I think these are important. – Umm… – Okay, I was guessing
you just pour that on, but I don’t know
what the Sharpies are for. – Just pour acetone
on his head? – That seems very straightforward. – I assume that acetone
will go right through Styrofoam. – I think so too.
– Just pour. – We’re gonna draw a face on it,
and then pour the acetone, and then it’s gonna look like
a little scary witch. – That’s it, you just pour
the acetone on the Styrofoam? – (FBE) Well you got it correct.
(bell rings) Go ahead and draw that face
and melt it off. – Can we do the honors?
– We need to turn this. – Let’s do blue eyes.
– Oh okay, she’s just going in. – You’re gonna give him eyeliner?
– No, he’s got demon eyes! – She’s obviously gonna have
a huge wing. – Uh huh.
– Like me. But no pupil.
– No pupil. – Because she’s like that.
– ‘Cause that’s spooky. And then she just, right?
– Aw, she’s wild. – She crazy. – Alright. (laughs)
Ew, yo! – I think we look alike. – Bowl cut and a soul patch. What a iconic look.
– (Noah) There you go. – I’m low key scared about this. – I can’t wait to see the…
– Let’s go, ooh! Oh, whoa!
(bell rings) (gasps) Are you ruining her face?
Oh my God! Whoa!
Yeah! (laughs) Whoa! – Gotta get the face.
– Goodbye! – (Carson) Whoa! – (Michelle) Your service here
was greatly appreciated. – (Carson) Holy crap,
that’s actually really, that’s really terrifying actually. – Heh.
– (Carson) That’s great, oh look at him now!
– Love that. Oh, my hand’s stuck to it.
– Aw, poor guy. – Let’s see it.
Oh my God! (bell rings) – (Ary) Oh my God.
– (Brandon) Yo! – (Ary) Her face is out of control.
– (Brandon) Oh! – Bye.
We didn’t even name her! – I’ve never seen that!
– That’s crazy! – (Brandon) Oh my God! – Oh gosh, I’m already scared.
– I wanna see how quick this is, of if it’s just gonna…
– (Chelsea) Oh my gosh! (bell rings) – (Noah) That is so cool. – This is so scary,
but so cool at the same time! It’s literally just melting
through the materials. – That is crazy.
– That’s insane! And look how the Sharpie
just comes off with… – (Noah) I’m literally from
Breaking Bad when he melts the bodies. – (FBE) Next, you’ll be doing
a carbon and sugar experiment with the items in front of you. – That sounds sick. – Now we’re lighting stuff on fire! – We take the sugar,
we take the baking soda, we take sand.
– Sand. – All across here,
then we light it on fire. Boom, yeah!
– No sir. – (FBE) Is that your final answer?
– No sir, that is not. – We lay down
a little bit of the lighter. – And let it dry. – And then we add
sugar and baking soda. And then we light it,
and then we’ll do a thing. – Which one of these
are like flammable? – Sugar will just burn. – Yeah, sugar will just
like burn and melt. But I guess maybe you’re using that
to catch the baking soda on fire? – The only guess I have, honestly,
is to put these with the sand, mix it, put the lighter fluid on it,
and light it on fire. – You’d put the baking soda
like in the shape you want, and then put the sugar on top of it
or below it? – (FBE) And then, what do you do
with the lighter fluid? – You trace it?
– Trace it around? – (FBE) That was perfect! – Oh my God, really?
– Yes! – (FBE) Yeah!
– Perfect! – (FBE) I’m gonna count this
as wrong. (buzzer rings)
– Okay, fine. – (FBE) First you’ll wanna coat
all the sand in lighter fluid, then you’ll mix together
the baking soda and sugar and dump it in the center. Light the lighter fluid all around it
and see what happens. – Oh, okay. – I really hope this works.
– Alright, let’s do it. – I feel like yeah,
goggles on for this one. – Okay, so the baking soda
and the sugar I’m gonna mix. – Love cooking.
– Mm-hmm. – Cooking’s so fun. – This is scary, guys!
Don’t try this at home. – Alright, good luck!
– Are you ready? Ready?
– Let’s go! – Ope, there it is!
– Ope! – (Brandon) There it goes. – Oh my God.
– Whoa! – (Ary) I feel so powerful right now.
(bell rings) – (Brandon) Aw man, dude, look. It’s burning up
all the baking soda and sugar. – (Michelle) Oh, I see it.
Oh God, this looks like a cyst. – (Carson) Oh, I see, that’s so cool.
What are you talking about? This is awesome! – Oh, we only got like
a little bit of it to burn. (buzzer rings)
But the part that is burning is like going scoop! – (Chelsea) It’s like a fun
little rock creature. – (Noah) It’s very relaxing too,
I gotta say. – Yeah, it’s nice to watch.
– I’m very relaxed. – (FBE) So finally, YouTubers
David Dobrik, Mark Rober, and Nick Uhas are all known
for participating in viral world record
elephant toothpaste experiments. – Oh, dude!
I’ve been wanting to do this! – (FBE) Do you think you can
figure it out? – Nope! (laughs) – So the hydrogren peroxide,
if we’re talking science, has got to be the catalyst
to the experiment, is my hypothesis. That’s as far as I’ve gotten. – So I think this will be
the vessel that will carry everything. The yeast and the hydrogen peroxide
will have to be mixed, and then we’ll apply…
– The hot water? – Will the order mess it up? – Yeah.
– [Bleep]! Activate the yeast,
and then we’re going to put this, the activated yeast in the bottle?
– Mm-hmm. – Wait, if you put the warm water
in the soap, that’s just gonna make soapy water. – Yeah, so that’s not it.
– That’s not gonna work. If you put hydrogen peroxide
in the soap… – No. – Dish soap, yeast, water,
hydrogen peroxide. (laughs) – (FBE) So you guys got it
fairly backwards. (buzzer rings)
– Okay. – (FBE) So you failed this round. – Oh no.
– Alright. – Whoa!
– Why? It was the other way, huh? – (FBE) First you’ll mix the yeast
and warm water, and let it sit. Then you’ll combine
the hydrogen peroxide, dish soap, and food coloring
in the bottle. Add the yeast and water,
and you’ll have elephant toothpaste. – Oh! – Let’s do it!
– Let’s do the yeast and the water. – Yeah.
– And then you can prepare that. – Sure.
– While this is waiting. – There we go, nice and gummy.
– Moist. – Hydrogen peroxide, bottle.
I trust you with this. – Do you?
– I’ll hold the bottle. We learned from our first experiment. – What color do you want it? – Uh, ooh.
Similar to blue, what do you think? – Let’s do red.
– Food coloring in there. Oh, it’s green and ugly again!
– Wow, I like that! – Then you stir it.
Then we pour the yeast in. – The whole yeast?
– Here, I got this one. And ope, ah.
– (Michelle) Carson! – (Carson) What, here I got this,
we’re doing… – (Michelle) Oh my God,
what are you doing? – (Carson) We’re doing it,
we’re doing it! (buzzer rings)
And nailed it. It’s the exact same thing
as Mentos and Diet Coke, just a longer, more…
– Recycle! – Uh, it’s not going,
that’s not going in. – (Michelle) It looks like a slushy. – High five!
– No. – It’s so slow!
– Okay. – Wait for it.
– Give it a second. (bell rings) – Yay, we did something! – Ooh, go, go, go, go, go, go, go!
– (Chelsea) Watch out, watch out! (bell rings)
– (Izzy) Ooh, it feels so gentle. – It was so gentle. I thought it was gonna go wah! – There it is, there it is,
let go, let go, let go, let go! (bell rings)
– (Ary) No! – Brilliant. – I wanted it to
shoot through the roof. – (Brandon) We’ll make it
shoot through the roof! – Yay!
That’s what we wanted. – Yay, it worked!
– Party! – It worked! (slowed) It worked! – (FBE) You guys got six points
out of a possible 10. – [Both] Woo! – See, we did good.
– We did pretty well. – Not bad!
– Woohoo, let’s go! That’s a passing grade! – Okay.
– That’s pretty decent. – It’s alright, I’ll take it.
– It’s like more than half. – (FBE) How much did working as a team
help you in this challenge today? – A lot.
– Oh, it helped me so nicely. – I would not have figured that out. – No no, team was definitely… – That was definitely better.
– It was definitely better. Teamwork makes the dream work, guys.
(laughs) – I feel like I needed those
Ary approvals to like go forward
with what we were doing. – I just wanted you to put more. – Your last two brain cells
passed science. – Thanks for watching us
Try Not To Fail Science Experiments on the REACT Channel. – Bye guys!
Science is cool! – Hey guys!
