Lava vs Lasers - Which Is More Destructive?

which has more destructive

power lava or lasers

well today we're going to answer that age-old

question with a bit of a scientific

faceof by testing each against seven objects

including a row of glass bottles

a bunch of popcorn kernels

a metal maze a can of beans

a bunch of matches

a canister of Highly flamable

butane and finally an actual

boat and since lava won the last showdown between Acid versus lava your questionable

safety method practicing Hawaiian sh

reigning Champion is back

Kevin the backyard scientist

and his laser wielding opponent in this matchup will be a former middle school

science teacher and a man who has appeared on Jimmy Kimmel Live possibly more

than Jimmy Kimmel himself

Science Bob flug Felder

but once again I'm not just going to be watching from the sidelines

cuz each of the seven objects will have to face my X Factor Method

Of Destruction that will be different for each object so for example that highly

flamable canister of utain gas might be dropped

into the path of two Katana spitting at 1500

RPM in a small room filled with open flames

and as expected the nerd Trash Talk

commenced immediately I love Kevin's cute little backyard builds you're going down Bob don't

go sleeping on The X Factor you got another excavator

hiding outside I'm basically Oprah

here because the winner of today's competition

gets a boat last time you said I'd win a car and we ended

up burning all the cars did you win a car

technically but well with that we

can Will William Will's back it smells like farts in here Mark somebody farted

I'll get you out Will

William don't you have better things to do yeah I do I've been planning

Open sauce is the world's greatest science and engineering

event featuring over 150

of your favorite YouTube creators you can meet in person

June 15th and 16th are the dates and you're supposed to fill out your

form that's why I'm here did you just advertise

on my channel yes so here is

money worth it so in exchange for once again crashing the party I sent

William off to find the official crunch Labs bin of

referee uniforms I forgot about that thing it was time to commence our seven

item showdown of Destruction

starting first with the row of glass bottles

what I have in my hand is a 3,000

W water cooled High powerered laser

this thing gets hotter than lava Kevin only a tiny spot it's all we

need I'm not even going to wear my glasses you have to wear your

glasses okay I'm sorry

here we go oh my goodness

W wa it's like a mini

volcano holy Bob slowly worked his laser through every bottle setting them up

oh so he could breezily

knock them down a so that's a good way to cut a glass in

half which was fair enough but could lava do better let's do it

nice and by the way if you've ever wondered how to make lava

all you do is stick rocks in a graphite Crucible

then heat them up to 3000°

F so that the Rocks just literally

melt and turn into their liquid form

look at that wow

that's actually hot hot lava

w wa I still got

up horrifying and amazing

that was also a lot faster than Bob's

can't argue with that and with the flame safely D it was now my

turn I would say Kevin

wins I I think I won that one right well they would soon live

to regret ever discounting

The X Factor cuz what they didn't know is when it comes to oversized

quadruple banded trigger lock slingshots

I'm a bit of a sharpshooter

what darn it darn it

it's harder than it looks all right

first try yes and uh yeah my slingshot

eventually handled all of them Mark you made this easy

it's Kevin let's go

next round so lava put the first points on the board as we moved

into the second event of the day to see which of us could most

effectively pop some popcorn

how did no one think of using a laser to pop popcorn

that's a no-brainer just like you

don't insult a guy with a military grade laser

3 2 1 wow

oh I see a colonel

look are they popping

yes what oh I may have set it on fire this looks repulsive

you haven't tasted it yet it's like a little bit burnt

see oh just needs more time but Bob's time was up do you have

a plan Kevin no

first just like this

man that's guy Fier

right there and then here we go

popcorn on top oh you really went for it oh yeah oh wow look

at the smoke is it off gassing and then burning

that's one of the

craziest things I've ever seen in my life

I think it's we got some

popcorn Kevin's popcorn was the clear winner in

quantity taste test but how is the

quality oh it's chewy

huh oh oh no that's not good

wow lacking severely lacking

just tastes like smoke that's

horrible which brought us to The X Factor

and this oddl looking Contraption

okay now I just turned

this should make popcorn

really really fast basic basically the way it works is you put the kernels

in the top of this mini chamber

and then you lock it closed

and heat it up over a small fire

which causes the air pressure to rise really high because the air can't expand

out like it wants to as it heats up this new pressure then pushes

back on each kernel

squeezing them in all around like a weighted blanket

to keep their kernel shape even though they're now totally hot enough to pop

into popcorn so after putting a liberal amount of butter and salt into this

bag here and then prying off the lid to the chamber

three two 1 you instantly

pop a th000 pieces of popcorn

as they're free to expand

now without all the extra air pushing them in

W wo and after a quick Shake

I'll be judge right pretty good it's really good actually if mine was covered

in salt and butter it would taste good too

yeah let's test it okay wait no winner is marked

and that meant the underdog X Factor was tied with lava as we moved

into round three the Metal Man

and science Bob's plan was to use a series of mirrors

to send his beam through the maze

straight to a balloon filled with flammable

gas o balloon fastest way to solve a maze is to use the speed

of light 3 2

1 powering and while it instantly got through the maze all of the mirrors

did too much to weaken the intensity of the beam Bob it didn't let

your flash paper can we just do it

manually only barely being

salvaged by the explosive ending and Kevin's take on the maze

was to turn it on its head you have to follow your own path

in life don't listen to the wall Society puts up for you you take

the Maze and you just melt it down

get him lava God

it's beautiful it already went through and the lava wasted no time in just

melting its way through every wall

W I might burn through this side too I can solve the maze 10

different ways but one was more than enough I think that was really cool

Kevin that's beautiful Kevin thank you I also think you didn't dis solve the

ma my submission for X Factor on maze

should be arriving now

right on time this

well there's no way she's fitting in that is my adorable

knes Kaye and Kaye what do we have in this box we have myet

squeaky squeaky can do the maze

yeah so we put a little motivation

at the end of The Maze and let squeaky

get to work and squeaky wasted no time in leaving the competition

in the dust come on

come on squeaky come on squeaky

turn around turn sque I can't believe this

worked oh that's so embarrassing for

you this is so bad Kaye can you tell him to go to the

Finish Line I can but I don't want

wait what come on there's something wrong with this mouse

okay okay okay okay

yes full body Out full body out

and what Science Bob attempted to console me with a scientific

explanation for squeaky cold feet mammals don't like being out in the open cuz

that's where predators are

so right now it's probably feeling a little more protection

so knowing this we gave squeaky

a nice protected VIP

line straight to the

cheese and soon enough

oh that's it go into science Bob's clothes that would be awesome yes

yes do it do it

so I set my adorable

needs Kaye off to wait it's your call how you want to play this

while we all waited for Williams's

final call I will say she cries easy

and while the judge deliberates

his final decision judge

you might have noticed

my backyard has once again sprung up in crunch laps and that's because to

help fight summer brain drain and make this your least boring summer

ever by popular demand

we're bringing back Camp crunch

labs and this year not only have we triple reinforced

the roof oh but we've also added

the fort nuts Treehouse

now just like last year it's a 12we

virtual Summer Camp featuring all new way bigger Mega experiments

that I do that look sort of like

this and then Super challenges

you do at home that look sort of like this and the best atome

super challenge submission of the whole summer gets a platinum ticket to come out

right here with me to be in the 12th and final summer

episode on top of that usually the crunch Labs build boxes where we build

a really fun toy together where I teach you all the juicy physics of

how they work comes every month but to coincide with the weekly Camp crunch

Labs videos and challenges

we can ship them to you every week so if you want a 12-week

summer camp where you can learn to think like an engineer

with 0% chance of bug bites and poison ivy just set to campc Crunch

labs.com where you can reserve one of the limited spots

and I'll see you at

camp now where were we I think it's time to make a call William

easy choice to make one second

make eye contact with k

first okay fine everybody

wins you're a winner

you're a winner the points are negated no one gets any points

which was perhaps deservedly

a way to call us all losers on that round as we moved on

to the tastiest round yet beans

welcome to the crunch lab's

kitchen here we go

warm them up gently

then they will be delicious

it's like he's welding beans

once they're warmed up gently

besides Bob you're leaking beans everywhere

this is a crime against beans

just like Grandma makes it smells like

Grandma it'ss like mildly room temperature beans

five stars so all Kevin's lava had to do was beat room temperature beans

this is going to be way better than your laser beans

Kevin you look like a chef from the

future thank you wa

oh oh my w

get away from the Kevin

okay okay cool Kev

I have never seen that happen before

it's like a alien egg omelet you are a futuristic

Chef look at that look at that but to be kind

and the floor is lava

we gave him the Mulligan

all the power of a volcano

versus these my wait that can of beans is going to explode

that's what I'm kind of worried about wait

Kevin Kevin I would put that down and get away from the bean get

away get away get away get

get away get get away from the bean Kevin join us it's getting bigger

it's going to explode bro well I know I want to get covered in

beans so we waited to see if these were truly some ticking time beans

this is horrifying the second I let my guard down it's going to explode

you look like a

muppet oh is that it

okay it punctured I knew you wouldn't do it and with these beans being

more bust than boom

we had to grab a can opener sing us out Kevin's

whoa never mind we

rolling oh my God my

steing they'll come back down any minute now that is quite possibly the biggest

loudest explosion we've ever had at crunch labs

and we've had a lot dude the floor is

slippery dude there's no beans

wait there's no more beans

what fortunately we found just enough for a taste

test oh go before moving on to the X Factor

there's more than one way to boil a can of beans

with a Twist they never saw coming because that clear container is actually a

vacuum chamber and by sucking out the air on the chamber I would lower

the pressure on the beans

causing them to boil you might have noticed this effect when you're at higher

elevation in the mountains where the air pressure is lower and it takes longer

for something like your ramen noodles to become soft even though the water is

boiling with less air pressure

the boiling point of water is as much as 10°

lower so the water just can't get as hot before it turns to steam

oh yes they're like rising out with the foam this disgusting

Mark looks like a root beer float wait till you taste it and once

it had been given enough time to really boil

I switched off the vacuum

letting the air rushed back in

as I prepared to

judge they colder than room

so you get negative points cuz you made the beans colder there's only one

of these that was memorable

and it was Kevin's Bean bomb

yes so Kevin pulled ahead by one point but it was still anybody's

game going into the matches round all right arguably

the most expensive way to light a match

oh oh my gosh

W the laser worked great although thanks to Bob's protective eyewear

basically missed the entire

back half so hard to see don't tell him don't tell him I mean

you're doing great Bob but even with his helmet handicap

Bob got the rest quickly

wow and now for Kevin's Contraption

a spaghetti pot with slots

he had cut in the bottom and then bolted it to the end of

a router motor hoping the cental force would fire the rapidly spinning

lava into the matches

3 2 one yeah nice

it was quick beautiful

and left a ton of flames

I can't believe it unfortunately for Kevin the Flames just weren't on the

no oh you're burning it with a crucible it's not even lava anymore

it got kind of sad here we go for the xfactor I filled a

squirt gun with acid in the hopes it would create an exothermic

reaction on the match heads causing them to ignite

I can have the minions bring you some lava I don't need your big

lava wa fire chemistry

I think you need a time lapse instead of highs speed mark

That's nerd trash talk

right there and so we did put it to a time lapse and we

found out that if we gave it enough time

it still burnt out

Science Bob had the most effective method of letting the fire

laser no way so Science Bob was finally on the board as we moved

into the flammable butane

cans we've been trying to answer some important science questions here and the world

wants to know what happens if we hit a laser

on a can of Highly flammable butane

what what what happens

well I don't know so we're going to find out oh 3

2 1 okay going down

going down I didn't think that was going to work

not what I was

expecting that's how you laser it was a strong start for laser

and now it was over to Lava to see see if it could be

toed Kevin I see we need bunker

protection for this oh why cuz it's going to be so good CU it's

going to be dangerous

that means it's good despite my best judgment I allowed Kevin to continue

as he attempted to ignite a butane

canister by dumping a bunch of lava on

it and the result was actually

gorgeous as the venting butane

forced the viscous flow of lava

streaming back up into the air

wo and when it was finally through look at the bubble on the floor

it left so much to see

wo look at the lava Spike on that obsidian

dagger and a lot to hear

that's W it's like lava ASMR

and even some stuff to wear I think we officially have the world's most

dangerous contact lenses but I could beat all that gentlemen

you'll find your butane

can attaches ceiling here with an electromagnet

if I push this

button it drops drops onto what well it drops onto

this helicopter that spins

these little arms they're not wooden arms

they are swords those are katas

I believe then what sternal

Flames all around in the container

to ignite the butane

so you took two swords and bolted them to a motor 1500

RPM Motor they're going to stay on

it in theory I lit the candles

as I prepared to say hello to VI Victory

and potentially goodbye to Crunch laabs

here we go spin her up

oh is that as fast as it can go

no oh no you should say stuff like

that okay I'm good there

okay here we go mark this is terrif

2 1 that was so

cool look perfect slice

I feel like The X Factor finally brought something interesting to the table

which put the scores

here headed into the final two-point

Showdown all right gentlemen

what do you think that one kind of looks like me yeah that's by

Design uh-oh I'm guessing this is not a race yeah your goal is to

sink a boat the lake had three boats in it each filled with a

self portrait mannequin and a few gas cans to make things more interesting

quite simply first to sink Bo winds

starting with Kevin who is resorting to some medieval

tactics Hey Kevin you know what I think of your a little catapult

what do you think

Bob I think it's really cool I hope it works

a Bob sorry I'm not good at Trash Talk bring in the lava

you guys don't have any minions

all right Kevin this better be cool oh we're locked and loaded here you

go you guys ready

3 2 1 fire

you didn't even get close to the boat I don't want to hurt myself

oh look it's sizzling

W all right more lava

3 2 1 fire

my God I should be splashing him with lava now water

fire I would have hit it but it missed

this is it Kevin launch lava at you

like normal people do

come on I think if we take the lava out of The Crucible it'll

go farther just straight projectiles

at this just a red hot Crucible

no Lava okay it was his last shot 3

2 1 so he gave it everything

oh and by sheer

luck he hit one of the gas can

triggers He Just Dropped a Bomb and kept going and we waited for the

ship to sink but alas

it did not wow cevin

my lava minions are

fired all right gentlemen

my strategy here is kind of simple Simple Man Simple strategy continuing with the

Medieval theme flaming Arrow

he doesn't even have a quiver he's just like strapping him to his back

by the way I got my archery mirror badge in Boy Scouts

is that why it's not catching on fire it looks like it's supposed to

catch on fire oh

yeah okay straight and

true oh my God

that was supposed to look

the x is back babbe

here we go got it

oh definitely the wind there is no

wind this is so

sad the lake is littered with arrows

oh people look up to you mark

oh yeah hey Arrow boy wait I thought you were good at trash talk

I was just going to say

good luck and I'm rooting for you well now I feel bad

quit being nice Bob

this is the last Arrow

all right I got to make this one count

okay here we go flaming

arrow dang it and then there was one

this game is rigged

and with my boat even less sunk than Kevin's

the stage was perfectly

set for Science Bob to steal away the victory

all right boys so now we have added an extender on here this is

a big moment because you're down by one but this is a two-pointer

I literally have to light myself on fire out there oh yeah sorry Bob

me and a Ryan C crested hair Doom I think it's a good look

it's way better than my regular hair

all right Bob Bob's about to pull a Titanic

two one okay firing

we got fire we got fire

hit it go cut the bone back Bob we have to let it cool

what the you still going still going oh yeah look at your you burned

yourself that's what I'm talking about

Bob you have no mercy

it's already dead Bob

I really want to win this it's sinking

I think it's sinking

Bob you animal Relentless

I mean I think you win so far but

and as the US

laser sunk into the watery

depths like any good Captain

Science Bob seest went down with the

ship look it can be anyone's game at this point will what's the call

it's golden hour you look incredibly handsome

but you're still the

loser Bob Bob did damage appreciate

you what you get a hug

and of course I promis you a brand new boat so there it is

oh that's my boat

but I don't want that boat

have you ever wanted to go ice skating without having to deal with all

that pesky cold ice or maybe fully investigate

the viscous effects of slime

or maybe use the power of science to make things go

boom in a bunch of different ways

well if so get ready for your least boring summer ever

what cuz Camp crunch laabs has you covered with the 12we

virtual summer camp now a big part of the fun are the weekly episodes

where we learn the really cool science behind Mega experiments

like this but I think my favorite part is seeing all the at home

super challenge submissions where you use your own creativity

and budding engineering skills to blow my mind in fact the best super challenge

submission of the whole summer gets a platinum ticket to come right out here

to be with me for the final episode

where as you can see we don't hold back any punches

on top of that usually the crunch flabs build box is where we build

a really fun toy together where I teach you all the juicy physics of

how they work comes every month

but to coincide with the weekly Camp crunch Labs videos and challenges

did it change anything

we can ship them to you every week for 12 weeks straight

so don't spend all summer

super bored as you forget everything you learned

last year and instead

attend Camp crunch Labs

where you'll have a

blast growing your brain in delightful

ways as you challenge yourself

and learn to think like an engineer

now cam crunch laabs is for all crunch laab subscribers

so if you haven't somehow subscribed

yet and head to campc Crunch labs.com

to reserve one of the limited spots and I'll see you at camp
