it's on sometime hmm
humans have already created a huge
garbage patch in the Pacific Ocean hmm
how big is the Great Pacific Garbage
Patch hmm it can't be bigger than me
you're unbelievable every year hum dum
around 8 million tons of plastic waste
in the ocean holy moley huh now since
plastic doesn't degrade easily whoo
it keeps floating in the oceans for
hundreds of years over time strong winds
and natural ocean currents caused this
plastic to gather in five massive
garbage patches the biggest garbage
patch of them all is the Great Pacific
Garbage Patch or a GP GP it is in the
Pacific Ocean between Hawaii and
California according to estimations
early 1.8 trillion plastic pieces are
floating in the GP GP which weigh about
90,000 tons also some people say that
the GP GP is twice the size of Texas hmm
environmentalists are actively trying to
develop alternatives for plastic
we should also contribute and reduce its
use on some is going to entertain you
with his 15 silly dance move watch one
move after every topic and give it a
super cool name in the comment section

topic latent heat of vaporization why
does steam cause more severe burns than
boiling water no it is because of latent
heat of vaporization latent heat of
vaporization is the amount of heat
energy required to change a unit mass of
liquid into vapor at atmospheric
pressure at its boiling point whoa whoa
whoa trust me everything just went over
my head
alright I'll explain it to you boiling
water contains only a specific amount of
heat energy required for it to boil
however as steam is formed from boiling
water it contains the heat energy of
boiling water along with the latent heat
of vaporization hence as steam has more
heat energy it can cause more severe
burns than boiling water topic
properties of a liquid why is it diver
able to cut through water in a swimming
pool ha simple because I taught them no
this is because of intermolecular force
huh
intermolecular force is the force of
attraction present in between the
molecules of solids liquids or gases
now the intermolecular forces and
liquids are not very strong bow this
means I'm the strongest of all
oh please listen since the
intermolecular forces are not strong the
molecules of a liquid are loosely packed
and they have empty spaces in between
them as a result the molecules can be
displaced from their original position
hence when a diver jumps into water its
molecules get displaced from their
original position and the diver is able
to cut through the water topic myopia
what causes nearsightedness excess
staring at junk food no when light from
an object enters our eyes our eye lens
bends it such that the image is formed
on the retina however in some people
this image is formed before the retina
such defect is called nearsightedness or
myopia a person with myopia cannot see
distant objects clearly but why wait
I'll explain to focus image of a distant
object on the retina our eye lens
becomes thin however in people with
myopia the lens cannot become adequately
thin
thus forming image before the retina and
making it difficult to see moreover when
the eyeball is elongated more than
normal the distance between the lens and
the retina increases resulting in the
formation of image before the retina
thus causing difficulty in seeing the
distant object

topic caffeine how does coffee keep you
awake by throwing an overnight party nah
home we perform our daily activities
like thinking and playing a byproduct
called adenosine is produced adenosine
slows down the brain activity but how in
our brain
there are adenosine receptors which are
perfectly molded for this adenosine when
the adenosine binds to these receptors
it activates them causing to slow down
the brain activity and thus making us
feel sleepy huh however drinking coffee
keeps us awake and we don't feel sleepy
this is because coffee contains a drug
called caffeine which after digestion
reaches our brain caffeine is
structurally similar to adenosine being
similar caffeine binds to the adenosine
receptors and thus blocks the adenosine
from binding hence as adenosine does not
find our receptors don't slow the brain
activity as a result we remain awake
[Music]
topic paper cups
why do paper cups hurt so much it is
because paper hates us no we use our
fingers and hands to sense our
surroundings hence they have more number
of nociceptors than any other parts of
our body
nociceptors are pain receptors that
respond to changing pressure temperature
etc now the edges of the paper are not
smooth but are rough or jagged oh
they're like a sod absolutely hence
sometimes when we rub our hands or
especially fingertips against the edges
it cuts them like a song activating the
nociceptors now as there are more
nociceptors on our hands we feel more
pain in addition to this the paper cut
might also have fragments of paper
containing chemicals which may irritate
the skin and thus increase the pain
[Music]
topic pins and needles
why do limbs fall asleep huh it
basically happens because of nerves
through nerves our brain communicates
with outward limbs Wow
nerves are so amazing yep however when
we cross our legs or sleep on an arm for
very long we apply pressure causing the
nerve pathways in its surrounding
arteries to squeeze hence the nerves do
not work properly and the arteries
cannot supply require nutrients to the
nerves as a result the signals sent by
our brain do not reach the limb thus we
cannot move it so you say that our limb
has fallen asleep also in some
situations some of these squeezed nerves
stop sending signals while some fire
hyper actively this gives us the
sensation of pins and needles what is
color blindness a color festival no
color blindness or color deficiency is a
vision problem now our eyes have
light-sensitive cells called rods and
cones can I put ice cream on these cones
you are just unbelievable rods are
responsible for black and white vision
they do not detect color whereas cones
detect color there are three types of
cones one cone perceives red light
another perceives cream and the third
perceives blue together these cones help
us to see the whole spectrum of colors
now in some cases when one or more types
of cones do not work properly it
is colorblindness people with such
deficiency have difficulty in
distinguishing between certain colors or
shades for example in red-green color
blindness the apple tree may appear like
this how can we smell things dude I
don't have a nose so I know hahaha at
the back of our nose there's a tissue
called olfactory epithelium it is
covered with a mucus this tissue has
specialized neurons called olfactory
receptor neurons there are about 40
million olfactory receptor neurons these
neurons are the receptors that is
neurons which detect chemicals Wow they
look cool name now when any substance
releases its smell or odor the odor
consists of chemicals when we breathe in
these chemicals enter our nose when they
reach the olfactory epithelium the
chemicals get stuck in the mucus causing
them to activate the neurons as a result
these activated neurons send signals
through the olfactory tract to the brain
informing it about the smell
[Music]
why do we get sunburned cuz son is
jealous of my skin oh no huh sunburn is
a term for red and inflamed skin it is
caused by ultraviolet radiation present
in sunlight sunlight consists of three
types of ultraviolet radiation UVA UVB
and UVC Oh does it contain UVC as well
oh just listen our skin is made up of
cells these cells have DNA when we are
in the hot Sun for very long the UVB
radiation enters into our skin cells and
starts to damage the DNA DNA damage can
lead to cancer thus to reduce the risk
of cancer the damaged skin cells kill
themselves
this programmed cell death is called
apoptosis apoptosis activates the immune
response as a result the blood flow
increases to that area to heal the skin
this leads to red and inflamed skin
which we call as sunburn how do I use
make honey no idea to make honey the
word endure honey bee sucks nectar from
flowers and stores it in its honey
stomach once the worker bee returns to
the hive it vomits the nectar into a
processor honey bees mouth Oh in the
processor bees mouth and stomach an
enzyme called invertase is added to the
nectar invertase break some nectar into
simple sugars like glucose and fructose
then it vomits the partially converted
nectar into another processor bees mouth
who also adds more invertase helping
break down more nectar this process goes
on until most of the nectar is converted
into simple sugars then the mixture of
simple sugars is stored in the honeycomb
at this point the mixture is still
watery
hence the bees flap their wings which
evaporates water and thickens the
mixture to eventually form honey why
does our stomach growl because there are
bears in our stomach now growling sound
is produced mostly due to movement of
gas in the digestive tract especially in
the intestines now guests can either
enter or be produced in the intestines
but how when we eat food very quickly
sometimes we swallow gas such as air
along with food besides this bacteria
and our intestines also produce gases
now during digestion the muscles of our
intestines contract in order to push
food ahead
however gas is also get pushed along
with food now as our intestines are
hollow tubes such movement of gases
produces growling sounds besides this
punker increases growling
this is because when we are hungry our
digestive system starts preparing for
the next meal hence it clears the
remains of last meal causing more muscle
contraction thus producing more growl
examples why do pop rocks pop because
they have springs in their legs now pop
rocks are tiny candy crystals candies
are usually made using sugar water corn
syrup various flavorings etc initially
all these ingredients are mixed together
the resulting solution is heated until
most of the water boils off and we are
left with a thick sticky syrup usually
this syrup is poured in modes and
allowed to cool and Harden to make
candies however to make pop rocks highly
pressurized carbon dioxide gas is added
to the syrup and then it is key to
subsequently form a hard candy this
results in the formation of small
bubbles of pressurized carbon dioxide
trapped inside the candy now when we put
this candy in our mouth our saliva
dissolves the candy as a result the
highly pressurized carbon dioxide
escapes from the bubbles with a pop how
do nails grow email consists of many
different parts the visible part of the
nail is called nail plate nail plate
lies on the nail bed can I sleep on that
bad oh just listen matrix is the area
where nail growth originates it lies
below the skin matrix as specialized
cells which keep dividing and creating
nail cells the nail cells grow and
produce a hard protein called keratin
then these keratin filled cells are
pushed forward as more new cells form
find them eventually the keraton filled
selves died and flattened to form the
nail plate the hard keratin in these
dead cells gives strength to the nail
and makes it hard but what is the use of
these nails nails protect our fingertips
moreover by observing the condition of
our nails doctors can get clues about
our over a health why do our fingers get
wrinkly cuz they want to look like
raisins no huh
a popular research suggests that wrinkly
fingers are a reaction of our nervous
system when our fingers are in water for
a long time our nervous system causes
the blood vessels present in the deeper
layers of our skin to constrict this in
turn causes the deeper layers to shrink
or contract but as the topmost layer
does not shrink it becomes loose thus
forming small folds or wrinkles but why
does this happen
scientists suggest that this could be an
evolutionary adaptation wrinkly fingers
help in getting a better grip to pick up
wet objects preventing them from
slipping from our hands even our feet
get wrinkly helping us to walk in water
without slipping
