A
Hi
and
welcome
back
to
it's
a
science
thing
thanks
for
joining
me
today,
we're
going
to
use
balloons
again
we're
going
to
use
balloons
in
a
different
way
used
balloons,
and
I
did
some
experiments
to
demonstrate
different
ways
to
inflate
the
balloon.
Besides,
just
using
my
breath
today,
we're
going
to
use
balloons
as
a
means
of
moving
other
objects
and
by
and
as
we
do,
this
we're
going
to
go
over
somebody,
a
famous
mathematician
and
physicist
named
isaac
newton.
Oh,
I
have
a
picture
of
him
right
here.
A
A
This
is
a
very
thick
straw,
it's
the
kind
of
straw.
It
you
get
thin
straws
when
you
go
out
to
eat,
usually
they're
just
bendy
thin
straws.
This
is
a
little
bit
thicker,
it's
kind
of
straw
you
might
get
if
you
want
to
drink
a
milkshake
or
something
like
that,
it's
a
little
bigger
around
a
little
fatter
on
it.
I
have
these
two
orange
pieces
of
reflective
tape,
so
you
can
see
it
as
it
moves.
It
is
on
this
stuff.
That's
caught!
A
A
His
first
law
so
he's
got
three
three
laws
of
motion.
The
first
one
is
saying
that
an
object
at
rest
will
stay
at
rest
and
an
object
in
motion
will
stay
in
motion
until
an
outside
force
acts
upon
it.
So
if
I,
if
this
were,
if
I
didn't,
have
a
balloon
attached
to
this-
and
I
wasn't
touching
it-
and
I
put
this
on
here
and
then
I
went
and
disappeared
for
100
years
and
nobody
else
ever
came
into
this
room.
A
This
will
probably
sit
here
until
something
comes
and
moves
it
or
something
happens
on
the
outside.
Maybe
a
breeze
would
come
in
and
make
this
wiggle,
or
maybe
this
would
I
don't
know
somehow
rot
can
fall
apart
and
the
string
will
fall.
Then
this
would
move,
maybe
there's
an
earthquake,
and
then
this
might
move
some
outside
force
has
to
act
upon
this.
To
move
this
straw
and
if
not,
it
will
just
sit
here
forever
in.
Is
it
there?
It's
inertia.
A
Basically,
what
is
what
that's
called
it's
a
theory
of
inertia
at
the
same
time,
also,
if
something
is
moving,
it
will
keep
on
moving
until
something
slows
it
down
and
eventually
stops
it
and
we'll
talk
about
that
as
I
after
I
let
this
go.
So
I'm
going
to
let
this
go
and
we
will
just
observe
before
we
do
anything
else.
So
here
we
go.
A
So
this
moved
and
it
stopped
because
it
bumped
into
here
into
the
sign
it
also
stopped
because
it
ran
out
of
string
it
stopped
because
it
ran
out
of
the
the
pressure
I
ran
out
of
this
motor
there's
no
more
air
when
the
air
runs
out.
This
thing
stops
moving,
so
there
are
a
lot.
There
are
different
reasons
why
this
stopped.
If
those
things
weren't
the
case
and
the
string
went
on
forever
and
ever
there
was
no
building,
it
wasn't
going
to
get
in
his
way.
A
It
would
just
keep
going
and
going
and
going
and
going
until
something
slowed
it
down.
When
I
originally
put
this
together,
I
did
not
use
fishing
line,
which
is
very,
very
smooth.
I
used
yarn
and
yarn
kind
of
has
little
threads
that
stick
up
and
that
slowed
it
down,
so
it
did
not
was
not
that
smooth.
I
also
used
a
smaller
straw,
a
thinner
straw,
and
that
was
really
the
threads
really
got
in
its
way.
So
it
slowed
it
down.
It
added
friction
and
slowed
it
down.
A
A
A
Will
the
balloon
go
guesses?
I
will.
I
will
let
you
guess
and
let
it
go
and
you
can
see
well,
you
know
because
I
did
it
before,
but
this
kind
of
explains
it
a
little
bit
right
when
I
open
this
up,
that
the
balloon
goes
this
way,
because
it's
the
opposite
direction
of
the
action,
which
is
the
air
coming
out
here
now,
if
I
flipped
it
around,
which
is
too
hard
to
do,
because
it
would
require
well.
A
Acceleration
is
how
fast
it's
going
so
with
this,
I
already
did
discuss
that.
It
was
slowed
down
by
a
couple
of
factors
having
to
do
with
the
string,
the
size
of
the
straw,
but
also
I
made
initially
when
I
made
this,
I
wanted
to
make
it
look
like
a
cool
rocket,
so
I
made
a
sort
of
rocket
out
of
a
toilet
paper
tube.
I
added
all
these
streamers,
so
it
looked
like
flames
coming
out.
A
This
ended
up
being
too
heavy
and
it
did
not
go
very
well
at
all,
even
though
the
balloon
was
the
same
size,
this
was
heavier
and
required
more
to
make
it
move.
So
that
is
sort
of
what
the
third
law
is
having
to
do
with
the
size
of
an
object
and
the
amount
of
force
needed
to
move
it
sort
of,
if
you
think
of
it.
A
A
It's
going
very
slow
and
it
does
not
go
very
far,
but
if
you
had
two
men
or
women
pushing
the
car,
the
car
will
go
twice
as
far
and
twice
as
fast
it'll
go
because
there's
two
people
working
on
that
same
size,
car.
If
you
have
three
people,
it
would
go
even
faster
same,
but
also,
if
you
think
about
it,
if
the
car
was
a
smaller
car
with
one
person
working
on
it,
the
car
would
move
faster
and
a
little
further
as
well,
because
the
one
person
could
move
the
smaller
mass
further.
A
A
A
Okay,
so
another
vehicle
that
I
made,
that
would
be
it's
going
to
be
powered
by
the
air
that
comes
out
of
the
balloon,
so
the
balloon
is
sort
of
its
motor
is
a
boat,
and
this
boat
is
the
very
bottom
of
a.
I
think
it
was
rice,
milk
or
almond
milk
container
that
I
cut
and
made
a
hole
through
the
bottom
and
put
a
straw
in.
I
will
actually
later
close
up,
show
you
how
some
of
these
things
can
be
made.
I
just
want
to
demonstrate
this
outside
in
this
pool.
A
A
A
The
reason
I
did
it
in
the
almond
milk
containers
because
it
can
hold-
obviously
it's
holding
milk,
so
it's
water,
it
can
hold
water
and
it
can
sit
in
water
without
disintegrating.
If
you
make
a
boat
out
of
paper,
it's
just
going
to
get
soggy
right
or
a
box,
it's
going
to
get
soggy
and
we
also
covered
it
with
duct
tape
to
keep
it
waterproof
ready.
Let's
do
it
in
the
middle
and
see
what
happens.
A
It's
moving,
it's
moving,
it's
moving
the
opposite
direction,
then
the
exhaust
pipe.
I
mean
this
is
sort
of
like
a
little
exhaust
pipe
here,
so
you
can
make
boats
too,
and
that
could
be
kind
of
fun
to
do
see
what
happens
if
you
make
the
boat
out
of
something
lighter
or
if
you
make
the
boat
smaller
or
if
you
make
this
taller,
will
it
move
any
faster
or
slower
and
differently?
Also,
I
mean
say:
I
used
a
balloon
that
was
bigger.
A
A
There
are
all
kinds
of
factors
that
can
cause
something
to
go
slower
or
faster
or
stop
it
moving.
Obviously,
this
is
going
to
stop
moving
because
the
balloon
is
going
to
run
out
of
air,
which
is
true
for
all
the
vehicles.
Once
the
once,
the
air
has
gone
out
of
the
balloon.
The
force
is
done
and
there's
nothing
acting
on
it
to
keep
it
moving
to
keep
it
moving.
So
it's
going
to
stop
moving.
A
A
A
The
first
one
is
a
car
that
I
made
out
of
a
staple
box
from
staples,
but
it
is
a
staple
box.
It
held
staples
it's
empty
now
and
I
put
tires
on
tires
that
were
bottle
caps
and
I
used
tacks
to
keep
them
on
as
a
sort
of
axle
just
little
individual
tax.
Then
I
taped
a
straw
to
the
top
with
a
balloon
and
we'll
see
how
this
one
moves,
I'm
going
to
blow
it
up
and
hopefully
you'll
be
able
to
see
it
through
the
camera.
There
ready.
A
A
A
I
don't
think
it's
completely
centered
in
the
middle
of
each
cap,
so
they
are
not
moving
in
in
a
perfect
circle
when
they're
going
around
and
around
the
caps
also
have
I
had
to
break
the
seal
when
you,
when
you
get
new
water
and
that
left
a
little
sort
of
ragged
edge
that
I
think
is
catching
on
the
carpet
here.
The
fact
that
it's
a
carpet
might
make
a
difference.
A
It
also
might
be
that
this
is
pretty
low
to
the
ground
and
the
blown
up
balloon
might
have
been
causing
drag,
might
have
been
dragging
and
slowing
it
down.
There's
a
lot
of
resistance
happening,
that's
slowing
this
vehicle
down,
and
these
also
aren't
completely
tight.
This
way,
so
they're
kind
of
going
like
this
and
maybe
even
bumping
into
the
box.
So
this
is
not
the
most
successful
design,
but
we
can
think
about
it
and
explain
why
and
maybe
make
some
changes.
A
I
made
another
one.
I
decided,
okay,
that
one
didn't
work
so
well,
let's
try
something
different,
so
I
made
one
out
of
a
scotch
tape
box,
which
is
a
different
shape.
It's
a
square,
it
is
also
low.
I
made
the
wheels
different
the
wheels
for
this
vehicle
are.
This
is
a
dowel
which
is
just
like
a
wooden
rod
that
I
cut
short-
and
I
put
I
hot
glue-
gunned
some
bottle
caps
there.
A
These
bottle
caps,
don't
have
that
break
area,
the
safety
catch
that
I
had
to
break
through.
So
it's
so
it's
smooth.
There
are
no
little
pieces
like
those
wheels.
This
is
going
to
spin
within
this,
which
is
a
receipt
roller,
so
it
so
it
spins
a
lot
smoother
than
those
separate
wheels.
Two
spin
together
at
a
time
for
this.
I
made
two
of
these
axles
and
then
I
glued
them
to
the
bottom
of
the
box.
Now
you
can
see
they
move
so
that
could
cause
an
issue.
A
A
Another
difference
is
that
this
car
I
used
a
skinny
straw
like
you,
would
get
at
a
fast
food
restaurant.
You
know
the
bendy
kind.
I
used
a
skinny
straw.
This
is
a
big
straw.
I
don't
know
if
that'll
make
a
difference
ready.
So
I
have
a
balloon
here.
The
air
is
going
to
shoot
out
here,
so
I
better
move
it
back.
Who
knows
how
fast
it's
gonna
go
ready?
I
have
high
hopes
for
this.
One
ready
go.
A
A
A
A
And
this
is
my
last
design
this
design.
These
are
not
wheels
that
I
made
you
might
recognize
them.
They
are
lego
wheels.
I
glued
lego
wheels
to
the
bottom
of
this
box.
I
can
take
them
off,
though,
so
we
can
use
the
lego
wheels
again.
This
box
is
a
lemon
extract
box
from
the
kitchen
and
I
covered
it
with
tape.
Duct
tape
glued
the
lego
wheels,
and
this
is
a
fat
straw
and
the
balloon
is
on
the
top
of
this
box.
It's
a
different
shaped
box.
A
A
Try,
let's
have
this
one
move
this
way
air
is
going
to
come
shooting
out
here,
so
it's
going
to
go
in
the
opposite
direction:
ooh
that
was
better.
That
was
better
a
lot
smoother
right.
It
does
better
on
the
carpet
than
the
other
ones,
and
that
might
have
to
do
with
the
fact
that
this
actually
has
like
a
wheel,
which
you
probably
know
it's
like
a
rubber
wheel,
so
that
that
works
better
on
the
carpet.
A
A
So
there
we
go.
I
think
this
also
stops
because
the
balloon
gets
in
its
way
kind
of
it
gets
under
the
wheels
a
little
bit.
This
could
go
further,
actually
also
the
size,
the
balloon.
If
this
was
a
big
big
balloon
like
that
one
I
used
over
there,
I
wondered
how
far
it
would
go.
Imagine
if
I,
if
I
filled
up
that
balloon
and
it
didn't
pop
and
it
was
huge
and
I
let
it
go.
Maybe
this
would
go
all
the
way
across
the
room.
A
I
don't
know,
does
a
bigger
balloon
make
it
go
faster
or
further
or
both,
so
that
is
experimenting
with
vehicles
that
have
wheels
and
using
a
balloon
as
its
motor
or
its
engine.
You
could
also
do
a
freewheeled
thing
if
you
wanted
to
that,
could
make
a
difference
right
so
maybe
find
some
things
around
the
house
and
ask
an
adult
which
you
are
allowed
to
use
not
allowed
to
use.
I'm
going
to
show
you
a
little
bit
later
how
to
make
some
of
these
things,
because
it
will
require
adult
supervision,
as
you
make
some
of.
