which has more destructive
0:01
power lava or lasers
0:03
well today we're going to answer that age-old
0:05
question with a bit of a scientific
0:07
faceof by testing each against seven objects
0:10
including a row of glass bottles
0:12
a bunch of popcorn kernels
0:14
a metal maze a can of beans
0:16
a bunch of matches
0:17
a canister of Highly flamable
0:19
butane and finally an actual
0:22
boat and since lava won the last showdown between Acid versus lava your questionable
0:27
safety method practicing Hawaiian sh
0:30
reigning Champion is back
0:32
Kevin the backyard scientist
0:35
and his laser wielding opponent in this matchup will be a former middle school
0:38
science teacher and a man who has appeared on Jimmy Kimmel Live possibly more
0:42
than Jimmy Kimmel himself
0:44
Science Bob flug Felder
0:46
but once again I'm not just going to be watching from the sidelines
0:49
cuz each of the seven objects will have to face my X Factor Method
0:53
Of Destruction that will be different for each object so for example that highly
0:57
flamable canister of utain gas might be dropped
1:00
into the path of two Katana spitting at 1500
1:02
RPM in a small room filled with open flames
1:06
and as expected the nerd Trash Talk
1:08
commenced immediately I love Kevin's cute little backyard builds you're going down Bob don't
1:13
go sleeping on The X Factor you got another excavator
1:15
hiding outside I'm basically Oprah
1:19
here because the winner of today's competition
1:21
gets a boat last time you said I'd win a car and we ended
1:24
up burning all the cars did you win a car
1:26
technically but well with that we
1:28
can Will William Will's back it smells like farts in here Mark somebody farted
1:33
I'll get you out Will
1:35
William don't you have better things to do yeah I do I've been planning
1:39
Open sauce is the world's greatest science and engineering
1:41
event featuring over 150
1:43
of your favorite YouTube creators you can meet in person
1:46
June 15th and 16th are the dates and you're supposed to fill out your
1:48
form that's why I'm here did you just advertise
1:50
on my channel yes so here is
1:52
money worth it so in exchange for once again crashing the party I sent
1:57
William off to find the official crunch Labs bin of
2:00
referee uniforms I forgot about that thing it was time to commence our seven
2:04
item showdown of Destruction
2:05
starting first with the row of glass bottles
2:08
what I have in my hand is a 3,000
2:10
W water cooled High powerered laser
2:12
this thing gets hotter than lava Kevin only a tiny spot it's all we
2:15
need I'm not even going to wear my glasses you have to wear your
2:18
glasses okay I'm sorry
2:19
here we go oh my goodness
2:22
W wa it's like a mini
2:24
volcano holy Bob slowly worked his laser through every bottle setting them up
2:30
oh so he could breezily
2:32
knock them down a so that's a good way to cut a glass in
2:36
half which was fair enough but could lava do better let's do it
2:40
nice and by the way if you've ever wondered how to make lava
2:44
all you do is stick rocks in a graphite Crucible
2:46
then heat them up to 3000°
2:48
F so that the Rocks just literally
2:50
melt and turn into their liquid form
2:53
look at that wow
2:54
that's actually hot hot lava
2:57
w wa I still got
3:16
up horrifying and amazing
3:19
that was also a lot faster than Bob's
3:21
can't argue with that and with the flame safely D it was now my
3:24
turn I would say Kevin
3:26
wins I I think I won that one right well they would soon live
3:30
to regret ever discounting
3:32
The X Factor cuz what they didn't know is when it comes to oversized
3:35
quadruple banded trigger lock slingshots
3:38
I'm a bit of a sharpshooter
3:40
what darn it darn it
3:44
it's harder than it looks all right
3:46
first try yes and uh yeah my slingshot
3:56
eventually handled all of them Mark you made this easy
3:59
it's Kevin let's go
4:01
next round so lava put the first points on the board as we moved
4:04
into the second event of the day to see which of us could most
4:07
effectively pop some popcorn
4:09
how did no one think of using a laser to pop popcorn
4:12
that's a no-brainer just like you
4:14
don't insult a guy with a military grade laser
4:17
3 2 1 wow
4:20
oh I see a colonel
4:22
look are they popping
4:23
yes what oh I may have set it on fire this looks repulsive
4:27
you haven't tasted it yet it's like a little bit burnt
4:30
see oh just needs more time but Bob's time was up do you have
4:35
a plan Kevin no
4:37
first just like this
4:40
man that's guy Fier
4:42
right there and then here we go
4:43
popcorn on top oh you really went for it oh yeah oh wow look
4:48
at the smoke is it off gassing and then burning
4:51
that's one of the
4:52
craziest things I've ever seen in my life
4:55
I think it's we got some
5:00
popcorn Kevin's popcorn was the clear winner in
5:06
quantity taste test but how is the
5:09
quality oh it's chewy
5:11
huh oh oh no that's not good
5:14
wow lacking severely lacking
5:18
just tastes like smoke that's
5:19
horrible which brought us to The X Factor
5:22
and this oddl looking Contraption
5:24
okay now I just turned
5:26
this should make popcorn
5:28
really really fast basic basically the way it works is you put the kernels
5:31
in the top of this mini chamber
5:33
and then you lock it closed
5:34
and heat it up over a small fire
5:36
which causes the air pressure to rise really high because the air can't expand
5:40
out like it wants to as it heats up this new pressure then pushes
5:44
back on each kernel
5:46
squeezing them in all around like a weighted blanket
5:48
to keep their kernel shape even though they're now totally hot enough to pop
5:52
into popcorn so after putting a liberal amount of butter and salt into this
5:56
bag here and then prying off the lid to the chamber
5:59
three two 1 you instantly
6:05
pop a th000 pieces of popcorn
6:07
as they're free to expand
6:09
now without all the extra air pushing them in
6:12
W wo and after a quick Shake
6:15
I'll be judge right pretty good it's really good actually if mine was covered
6:19
in salt and butter it would taste good too
6:21
yeah let's test it okay wait no winner is marked
6:25
and that meant the underdog X Factor was tied with lava as we moved
6:28
into round three the Metal Man
6:29
and science Bob's plan was to use a series of mirrors
6:32
to send his beam through the maze
6:34
straight to a balloon filled with flammable
6:36
gas o balloon fastest way to solve a maze is to use the speed
6:40
of light 3 2
6:41
1 powering and while it instantly got through the maze all of the mirrors
6:46
did too much to weaken the intensity of the beam Bob it didn't let
6:49
your flash paper can we just do it
6:52
manually only barely being
6:56
salvaged by the explosive ending and Kevin's take on the maze
6:59
was to turn it on its head you have to follow your own path
7:02
in life don't listen to the wall Society puts up for you you take
7:05
the Maze and you just melt it down
7:07
get him lava God
7:12
it's beautiful it already went through and the lava wasted no time in just
7:16
melting its way through every wall
7:22
W I might burn through this side too I can solve the maze 10
7:26
different ways but one was more than enough I think that was really cool
7:30
Kevin that's beautiful Kevin thank you I also think you didn't dis solve the
7:33
ma my submission for X Factor on maze
7:37
should be arriving now
7:41
right on time this
7:43
well there's no way she's fitting in that is my adorable
7:45
knes Kaye and Kaye what do we have in this box we have myet
7:49
squeaky squeaky can do the maze
7:52
yeah so we put a little motivation
7:53
at the end of The Maze and let squeaky
7:55
get to work and squeaky wasted no time in leaving the competition
7:59
in the dust come on
8:02
come on squeaky come on squeaky
8:04
turn around turn sque I can't believe this
8:07
worked oh that's so embarrassing for
8:10
you this is so bad Kaye can you tell him to go to the
8:13
Finish Line I can but I don't want
8:16
wait what come on there's something wrong with this mouse
8:19
okay okay okay okay
8:21
yes full body Out full body out
8:24
and what Science Bob attempted to console me with a scientific
8:34
explanation for squeaky cold feet mammals don't like being out in the open cuz
8:37
that's where predators are
8:39
so right now it's probably feeling a little more protection
8:42
so knowing this we gave squeaky
8:43
a nice protected VIP
8:45
line straight to the
8:47
cheese and soon enough
8:50
oh that's it go into science Bob's clothes that would be awesome yes
8:56
yes do it do it
8:58
so I set my adorable
8:59
needs Kaye off to wait it's your call how you want to play this
9:02
while we all waited for Williams's
9:03
final call I will say she cries easy
9:06
and while the judge deliberates
9:07
his final decision judge
9:09
you might have noticed
9:11
my backyard has once again sprung up in crunch laps and that's because to
9:15
help fight summer brain drain and make this your least boring summer
9:19
ever by popular demand
9:22
we're bringing back Camp crunch
9:24
labs and this year not only have we triple reinforced
9:28
the roof oh but we've also added
9:31
the fort nuts Treehouse
9:33
now just like last year it's a 12we
9:35
virtual Summer Camp featuring all new way bigger Mega experiments
9:39
that I do that look sort of like
9:41
this and then Super challenges
9:44
you do at home that look sort of like this and the best atome
9:47
super challenge submission of the whole summer gets a platinum ticket to come out
9:51
right here with me to be in the 12th and final summer
9:55
episode on top of that usually the crunch Labs build boxes where we build
9:59
a really fun toy together where I teach you all the juicy physics of
10:02
how they work comes every month but to coincide with the weekly Camp crunch
10:06
Labs videos and challenges
10:08
we can ship them to you every week so if you want a 12-week
10:11
summer camp where you can learn to think like an engineer
10:14
with 0% chance of bug bites and poison ivy just set to campc Crunch
10:18
labs.com where you can reserve one of the limited spots
10:21
and I'll see you at
10:22
camp now where were we I think it's time to make a call William
10:26
easy choice to make one second
10:28
make eye contact with k
10:29
first okay fine everybody
10:31
wins you're a winner
10:33
you're a winner the points are negated no one gets any points
10:36
which was perhaps deservedly
10:38
a way to call us all losers on that round as we moved on
10:40
to the tastiest round yet beans
10:43
welcome to the crunch lab's
10:45
kitchen here we go
10:49
warm them up gently
10:51
then they will be delicious
10:53
it's like he's welding beans
10:55
once they're warmed up gently
10:56
besides Bob you're leaking beans everywhere
10:59
this is a crime against beans
11:01
just like Grandma makes it smells like
11:04
Grandma it'ss like mildly room temperature beans
11:07
five stars so all Kevin's lava had to do was beat room temperature beans
11:12
this is going to be way better than your laser beans
11:14
Kevin you look like a chef from the
11:16
future thank you wa
11:22
oh oh my w
11:35
get away from the Kevin
11:36
okay okay cool Kev
11:41
I have never seen that happen before
11:44
it's like a alien egg omelet you are a futuristic
11:47
Chef look at that look at that but to be kind
11:50
and the floor is lava
11:51
we gave him the Mulligan
11:53
all the power of a volcano
11:54
versus these my wait that can of beans is going to explode
12:05
that's what I'm kind of worried about wait
12:07
Kevin Kevin I would put that down and get away from the bean get
12:09
away get away get away get
12:10
get away get get away from the bean Kevin join us it's getting bigger
12:15
it's going to explode bro well I know I want to get covered in
12:17
beans so we waited to see if these were truly some ticking time beans
12:22
this is horrifying the second I let my guard down it's going to explode
12:26
you look like a
12:27
muppet oh is that it
12:30
okay it punctured I knew you wouldn't do it and with these beans being
12:33
more bust than boom
12:35
we had to grab a can opener sing us out Kevin's
12:45
whoa never mind we
12:51
rolling oh my God my
12:54
steing they'll come back down any minute now that is quite possibly the biggest
12:59
loudest explosion we've ever had at crunch labs
13:02
and we've had a lot dude the floor is
13:05
slippery dude there's no beans
13:08
wait there's no more beans
13:10
what fortunately we found just enough for a taste
13:13
test oh go before moving on to the X Factor
13:17
there's more than one way to boil a can of beans
13:20
with a Twist they never saw coming because that clear container is actually a
13:24
vacuum chamber and by sucking out the air on the chamber I would lower
13:27
the pressure on the beans
13:29
causing them to boil you might have noticed this effect when you're at higher
13:32
elevation in the mountains where the air pressure is lower and it takes longer
13:35
for something like your ramen noodles to become soft even though the water is
13:38
boiling with less air pressure
13:40
the boiling point of water is as much as 10°
13:43
lower so the water just can't get as hot before it turns to steam
13:47
oh yes they're like rising out with the foam this disgusting
13:51
Mark looks like a root beer float wait till you taste it and once
13:54
it had been given enough time to really boil
13:57
I switched off the vacuum
13:58
letting the air rushed back in
14:00
as I prepared to
14:05
judge they colder than room
14:07
so you get negative points cuz you made the beans colder there's only one
14:10
of these that was memorable
14:11
and it was Kevin's Bean bomb
14:13
yes so Kevin pulled ahead by one point but it was still anybody's
14:17
game going into the matches round all right arguably
14:20
the most expensive way to light a match
14:22
oh oh my gosh
14:24
W the laser worked great although thanks to Bob's protective eyewear
14:29
basically missed the entire
14:30
back half so hard to see don't tell him don't tell him I mean
14:33
you're doing great Bob but even with his helmet handicap
14:36
Bob got the rest quickly
14:39
wow and now for Kevin's Contraption
14:42
a spaghetti pot with slots
14:44
he had cut in the bottom and then bolted it to the end of
14:46
a router motor hoping the cental force would fire the rapidly spinning
14:50
lava into the matches
14:52
3 2 one yeah nice
15:03
it was quick beautiful
15:05
and left a ton of flames
15:07
I can't believe it unfortunately for Kevin the Flames just weren't on the
15:12
no oh you're burning it with a crucible it's not even lava anymore
15:16
it got kind of sad here we go for the xfactor I filled a
15:19
squirt gun with acid in the hopes it would create an exothermic
15:22
reaction on the match heads causing them to ignite
15:25
I can have the minions bring you some lava I don't need your big
15:28
lava wa fire chemistry
15:34
I think you need a time lapse instead of highs speed mark
15:36
That's nerd trash talk
15:38
right there and so we did put it to a time lapse and we
15:42
found out that if we gave it enough time
15:44
it still burnt out
15:45
Science Bob had the most effective method of letting the fire
15:49
laser no way so Science Bob was finally on the board as we moved
15:53
into the flammable butane
15:54
cans we've been trying to answer some important science questions here and the world
15:58
wants to know what happens if we hit a laser
16:00
on a can of Highly flammable butane
16:02
what what what happens
16:04
well I don't know so we're going to find out oh 3
16:06
2 1 okay going down
16:11
going down I didn't think that was going to work
16:22
not what I was
16:23
expecting that's how you laser it was a strong start for laser
16:27
and now it was over to Lava to see see if it could be
16:29
toed Kevin I see we need bunker
16:32
protection for this oh why cuz it's going to be so good CU it's
16:35
going to be dangerous
16:40
that means it's good despite my best judgment I allowed Kevin to continue
16:43
as he attempted to ignite a butane
16:45
canister by dumping a bunch of lava on
16:49
it and the result was actually
16:54
gorgeous as the venting butane
16:57
forced the viscous flow of lava
16:59
streaming back up into the air
17:02
wo and when it was finally through look at the bubble on the floor
17:06
it left so much to see
17:08
wo look at the lava Spike on that obsidian
17:10
dagger and a lot to hear
17:13
that's W it's like lava ASMR
17:20
and even some stuff to wear I think we officially have the world's most
17:23
dangerous contact lenses but I could beat all that gentlemen
17:26
you'll find your butane
17:27
can attaches ceiling here with an electromagnet
17:30
if I push this
17:31
button it drops drops onto what well it drops onto
17:35
this helicopter that spins
17:37
these little arms they're not wooden arms
17:40
they are swords those are katas
17:43
I believe then what sternal
17:45
Flames all around in the container
17:48
to ignite the butane
17:49
so you took two swords and bolted them to a motor 1500
17:52
RPM Motor they're going to stay on
17:54
it in theory I lit the candles
17:57
as I prepared to say hello to VI Victory
17:59
and potentially goodbye to Crunch laabs
18:02
here we go spin her up
18:04
oh is that as fast as it can go
18:07
no oh no you should say stuff like
18:13
that okay I'm good there
18:15
okay here we go mark this is terrif
18:18
2 1 that was so
18:38
cool look perfect slice
18:41
I feel like The X Factor finally brought something interesting to the table
18:45
which put the scores
18:46
here headed into the final two-point
18:48
Showdown all right gentlemen
18:49
what do you think that one kind of looks like me yeah that's by
18:52
Design uh-oh I'm guessing this is not a race yeah your goal is to
18:55
sink a boat the lake had three boats in it each filled with a
18:58
self portrait mannequin and a few gas cans to make things more interesting
19:02
quite simply first to sink Bo winds
19:04
starting with Kevin who is resorting to some medieval
19:07
tactics Hey Kevin you know what I think of your a little catapult
19:09
what do you think
19:10
Bob I think it's really cool I hope it works
19:13
a Bob sorry I'm not good at Trash Talk bring in the lava
19:17
you guys don't have any minions
19:19
all right Kevin this better be cool oh we're locked and loaded here you
19:22
go you guys ready
19:23
3 2 1 fire
19:42
you didn't even get close to the boat I don't want to hurt myself
19:45
oh look it's sizzling
19:48
W all right more lava
19:49
3 2 1 fire
19:55
my God I should be splashing him with lava now water
20:01
fire I would have hit it but it missed
20:03
this is it Kevin launch lava at you
20:06
like normal people do
20:14
come on I think if we take the lava out of The Crucible it'll
20:18
go farther just straight projectiles
20:20
at this just a red hot Crucible
20:22
no Lava okay it was his last shot 3
20:25
2 1 so he gave it everything
20:31
oh and by sheer
20:34
luck he hit one of the gas can
20:41
triggers He Just Dropped a Bomb and kept going and we waited for the
20:45
ship to sink but alas
20:47
it did not wow cevin
20:49
my lava minions are
20:51
fired all right gentlemen
20:53
my strategy here is kind of simple Simple Man Simple strategy continuing with the
20:57
Medieval theme flaming Arrow
21:01
he doesn't even have a quiver he's just like strapping him to his back
21:04
by the way I got my archery mirror badge in Boy Scouts
21:07
is that why it's not catching on fire it looks like it's supposed to
21:10
catch on fire oh
21:14
yeah okay straight and
21:21
true oh my God
21:23
that was supposed to look
21:25
the x is back babbe
21:27
here we go got it
21:29
oh definitely the wind there is no
21:32
wind this is so
21:35
sad the lake is littered with arrows

have you ever wanted to go ice skating without having to deal with all
24:03
that pesky cold ice or maybe fully investigate
24:06
the viscous effects of slime
24:08
or maybe use the power of science to make things go
24:11
boom in a bunch of different ways
24:14
well if so get ready for your least boring summer ever
24:17
what cuz Camp crunch laabs has you covered with the 12we
24:20
virtual summer camp now a big part of the fun are the weekly episodes
24:24
where we learn the really cool science behind Mega experiments
24:27
like this but I think my favorite part is seeing all the at home
24:30
super challenge submissions where you use your own creativity
24:33
and budding engineering skills to blow my mind in fact the best super challenge
24:37
submission of the whole summer gets a platinum ticket to come right out here
24:40
to be with me for the final episode
24:42
where as you can see we don't hold back any punches
24:46
on top of that usually the crunch flabs build box is where we build
24:49
a really fun toy together where I teach you all the juicy physics of
24:52
how they work comes every month
24:54
but to coincide with the weekly Camp crunch Labs videos and challenges
24:57
did it change anything
24:58
we can ship them to you every week for 12 weeks straight
25:02

25:03
super bored as you forget everything you learned
25:06

25:10
where you'll have a
25:12
blast growing your brain in delightful
25:15
