A
So
we're
going
to
take
scissors
and
we're
going
to
cut
that
part
off
just
towards
the
very
edge
of
it,
so
that
this
thing
that
little
it's
just
a
little
ring.
We
don't
want
that,
but
we
want
this.
What
we're
going
to
do
is
we're
going
to
take
a
straw
I
use
for
purposes
of
it
being
visible,
more
visible
for
you
to
see
because
it's
colored,
I
do
use
electric
tape
because
it's
just
more
it's
flexible
and
it
makes
a
better
seal
around
the
straw.
A
A
I
put
the
straw
into
the
beginning
of
the
balloon
there
just
so
that
there's
enough
hanging
over
maybe
about
that
much
I'm
going
to
take
the
tape,
try
to
make
the
balloon
pretty
tight.
You
might
have
to
fold
the
balloon
a
little
bit
over
to
make
it
nice
and
tight
and
then
you're
going
to
tape
all
along
that
edge.
A
A
A
A
A
A
These
are
all
balloon
powered,
so
you
can
look
around
your
house
and
see
what
you
can
find
this
one
is
paper
clip
box
and
this
one
is
a
scotch
tape
box
and
this
one
was
a
vanilla
or,
I
think,
an
abs,
an
extract,
abstract,
extract
box
that
that
little
bottle
went
in.
um
You
could
also
use
a
cute
tip
box
or
whatever
I
got
here,
ballpoint
pen
box.
This
could
be
a
little
tricky.
It's
it's
long.
So
I'm
not
sure
how
many
wheels
you
would
want
to
use
for
something
like
this.
A
A
This
car
was
lego
wheels.
There
is
lego
wheels
that
I
can
put
on
the
thing
with
wheels
is
you're.
Gonna
need
four
if
you're
making
a
car-
um
and
they
have,
they
don't
have
the
colors
might
happen
to
match,
because
I
had
four
of
the
same
color,
but
they
do
not
have
to
match
any
color.
They
do
need
to
match
in
size.
However,
or
else
your
vehicle
won't
ride
smoothly,
so
different
colored
bottle
caps
can
still
match
what
you
want
to
do
is
test
it.
A
These
are
soda
bottle,
caps
that
I've
collected
and
if
I
line
them
up
whoops,
if
I
line
them
up
they're
the
same
size,
so
that'll
work,
okay,
they
can
roll
at
the
same
um
at
the
same
rate
or
rotate
at
the
same
rate.
If
it
was
something
like
this,
you
would
have
a
problem.
They
are
not
the
same
size.
Okay,
so
you're
gonna
find
four
caps
bottle
caps
that
are
the
same
size.
A
Now
there
are
options
on
how
to
connect
wheels
to
the
base
of
your
car.
This
one,
the
way
that
I
did
it.
If
you
can
see
that
is
I
took
them.
I
made
holes
in
the
middle
of
each
wheel
and
then
I
stuck
a
tack
in
that
hole
to
attach
it
to
the
box,
so
it
has
four
separate
little
axles
or
hubs
in
the
middle
of
each
wheel.
Each
wheel
moves
separately.
I
can
move
one
one
way
and
one
the
other
way
with
my
hands.
A
If
I
wanted
to
okay,
that
is
separate
wheels
or
you
can
do
it
where
two
wheels
are
on
one
axle,
so
two
wheels
move
together:
okay,
that's
a
that's
a
a
car
with
axles
and
an
axle
is
like
this,
this
um
dowel
or
like
a
rod
that
goes
through
something
and
then
the
two
wheels
attach
on
either
side.
So
basically
I
used
here.
This
is
a
receipt
roller
that
we
have
here
at
work.
It's
hollow
goes
all
the
way
through,
so
I
put
the
dowel
through
it
and
then
I
glued
the
two.
A
A
Would
you
like
it
to
be
separate
wheels
that
move
each
on
its
own
or
wheels
that
have
an
axle
and
two
wheels
go
at
once,
once
you've
decided
that,
then
we
proceed
with
figuring
out
how
to
make
the
wheels
attach
for
this
one.
This
one
does
have
a
hole
in
the
middle
and
and
putting
a
hole
in
the
center
of
a
bottle.
Cap
can
be
a
little
tricky.
A
I
do
have
some
tips,
though,
first
of
all
you're
going
to
need
some
cardboard
um
and
I
double
layered
this,
because
you're
going
to
put
a
nail
through
this,
you
do
not
want
to
nail
into
the
table
right
and
you
also
want
a
little
a
little
cushion
to
do
it
on
now.
The
important
part
about
putting
a
hole
in
the
middle
of
the
bottle
cap
is
getting
it
centered.
A
It
may
not
seem
like
that
much
of
a
big
deal,
but
it
really
actually,
if
you
don't
get
it
centered,
I
did
one
that's
actually
off
center
to
show
you
what
might
happen.
If
you
do
not
get
the
hole
in
the
center
of
the
wheel,
it
will
not.
It
will
not
um
spin
evenly
it.
It
spins
bumpy,
bumpity
bumpity
bumpy
bumpy.
You
see
it
does
not
spin
smoothly
because
it
is
not
in
the
center.
So
what
you're
going
to
want
to
do?
A
When
I,
when
I
get
the
center
or
what
I
think
is
the
center,
I
make
a
mark
on
it,
because
that
helps
me
keep
the
nail
right
on
that
dot.
So
I
have
a
mark
in
the
center
and
then
what
I
can
do
is
take
a
nail,
and
this
is
to
do
um
adult
supervision
right.
You're
gonna
take
a
nail
and
do
I
have
a
skinny
nail
yeah.
A
I
do
I'm
going
to
start
with
a
skinny
nail,
it's
just
easier
to
make
it
go
through
the
plastic,
so
you're
going
to
hold
it
right
in
the
center
of
that
dot
that
you
made
and
without
getting
your
hands
you're
going
to
tap
a
little
hole
through
it.
Okay.
Now,
if
the
hole
is
tight,
it's
not
going
to
spin
on
that
axle.
A
A
It's
not
going
to
get
stuck
stuck
because
the
hole
is
too
snug,
so
there's
the
hole
in
the
center.
Then
you
take
your
box
and
this
is
going
to
be
the
q
tip
box.
I'm
going
to
use
and
you're
going
to
take
something.
I
used
a
tack.
I
suppose
it
could
be
a
nail
and
you
are
going
to
stick
it
right
into
the
cardboard
box.
Remember
the
box
is
empty,
you've
emptied
the
box
out,
then
there's
your
wheel
going
round
and
round.
A
A
You
are
going
to
want
a
couple
of
things
for
this
one.
I
used.
I
used
a
wooden
rod
for
the
center.
I
do
not
have
a
saw
or
wooden
rod
to
show
you,
so
I'm
going
to
make
it
out
of
something
different,
I'm
going
to
make
it
using
a
straw
which
might
be
something
you
have
at
home
anyways.
This
is
these.
Has
this?
These
are
skinny
straws,
the
kind
that
are
bendy.
A
A
A
A
A
But
before
you
do
that,
you
need
to
make
yourself
a
this
is
the
axle
I
call
it
an
axle
holder
if
I
took
this
and
let
me
move
this
off.
If
I
took
this
box
and
glued
the
axle
onto
the
box,
it
would
not
roll
because
it's
glued
it
needs
to
have
something
for
this
to
go
into
that.
Let
allows
it
to
roll
this,
I'm
calling
it
the
axle
holder
does
get
glued
onto
the
box.
A
A
A
So
here
we
go.
I'm
going
to
put
a
blob
of
glue
on
in
the
middle
of
this,
um
the
middle
of
this
bottle
cap
when
I'm
putting
when
I'm
hold
when
I'm
putting
this
down
in
the
center
to
glue
it
in.
I
have
to
hold
on
to
this
um
axle
holder,
because
we
don't
want
this
to
get
stuck
in
the
glue.
This
needs
to
be
free,
moving,
I'm
putting
my
blob
in
there.
I
think
I
might
need
another
glue
stick
here.
We
go
I'm
putting
a
blob
of
glue
in
the
center
of
this
bottle
cap.
A
Okay,
here's
my
blob,
I'm
going
to
hold
the
axle
holder
with
my
hand
and
take
the
end
of
the
axle
itself,
which
is
the
skinny
straw
and
put
it
right
in
the
center
of
the
wheel
and
I'm
going
to
hold
it
there
until
it
dries,
which
might
take
a
minute.
So
I
might
end
up
turning
off
the
camera,
so
I
don't
waste
the
battery.
A
Same
idea,
so
these
are
dry.
I
held
this
up.
The
um
I
held
the
axle
covers
away
from
the
glue,
so
they
both
spin.
Okay,
one
thing
that
I
came
upon
a
little
problem,
but
I
can
fix
it,
um
but
it's
a
good
thing
to
remember,
because
I
didn't
one
of
them.
One
of
them
is
wider
than
the
other,
because
well
just
turned
out
to
be
that
way.
A
A
It's
touching
on
this
one
on
this
one,
it's
free
to
go!
Okay,
so
I'm
going
to
change
my
box.
So
at
first
you
don't
succeed.
Try
again
I'm
going
to
take
another
box.
This
is
a
staples
box
and
I'm
going
to
empty
it
out.
So
remember
to
ask
before
you
do
stuff
before
you
go
around
your
house
emptying
boxes.
Okay,
this
box
is
a
little
skinnier
than
the
q-tip
box,
so
I
think
it
might
be.
um
It
might
serve
our
purposes
a
little
bit
better.
A
So
I'm
going
to
use
staple
box;
instead,
we
are
going
to
end
up
turning
that
into
our
car,
so
we
need
to
now
attach
the
axle
cover.
I'm
going
to
take
hot
glue
again
for
these
things
you
can
use
regular
glue.
It
just
would
take
a
long
time
to
dry
and
it
may
not
dry
as
strongly
it
might
not
um
adhere
as
strongly.
So
I
do
recommend
a
glue
gun.
A
As
long
as
there
is
an
adult
helping
you,
so
I
think
this
is
hot
enough.
What
I'm
going
to
do
is,
I
think,
I'm
going
to
position
them
before,
so
I
think
I'm
going
to
have
one
there
and
one
there
pretty
evenly
spaced,
I'm
going
to
take
the
glue
gun
and
I'm
going
to
make
a
line
right
where
I
want
that
axle
cover
to
be.
A
A
Dry,
the
wheels
are
spinning,
so
they
are
not
getting
stuck
in
the
glow,
which
is
very
important.
So
that's
that
one
and
try
to
make
it
pretty
straight
so
that
the
car
will
stay
in
a
straight
track.
I'm
going
to
do
the
same
thing
for
this
second
one.
I
don't
know.
If
you
can
see
this.
Hopefully
you
can
I'm
going
to
make
a
straight
line
of
glue
right
across.
A
A
Actually,
I
will
show
you
this
is
just
this
is
just
um
that
box
and
I
just
hot
glue
gun
um
lego
wheels
on
and
it
goes
and
afterwards
I
could
pull
the
lego
wheels
off
and
take
off
the
hot
glue,
because
it's
very
easy
to
peel
it
off
and
I
won't
have
ruined
my
legos.
I
can
still
use
the
legos
in
my
lego
collection
and
these
run
very
smoothly.
A
These
run
with
an
axle
that
goes
through
the
lego,
brick,
but
they
can,
but
it's
loose
enough,
that
they
can.
um
They
can
spin
separately.
At
least.
I
think
that's
true
well
in
order
to
figure
that
out
for
sure
I
would
have
to
take
one
of
these
wheels
off
and
I
don't
want
to
ruin
the
lego,
so
it
could,
I
suppose,
be
the
other
way
too.
A
And
it
rolls
a
little
warpy,
but
it
does
roll
and
then
what
you
would
do
next,
as
the
last
thing
on
your
car
would
be,
you
would
take
your
balloon
on
a
straw
and
you
would
put
it
right
in
the
center
of
the
car
leave
enough
space
so
that
the
knot
so
that
there's
a
straw
a
little
bit
of
straw
hanging
off.
So
you
can
put
your
mouth
on
there,
so
you
can
blow
it
up,
okay
and
then
you
are
going
to
attach
it
again.
I
use
electrical
tape.
A
A
A
A
A
A
This
is
the
boat
that
I
had
made
and
showed
earlier.
The
boat
in
the
pool
outside
this
boat
was
actually
made
out
of
the
bottom
of
this
almond
breeze
container.
I
just
cut
the
bottom
off
I'll
show
you
it
was
like
this.
I
cut
the
bottom
off
and
then
covered
it
with
tape.
Now
I
wouldn't
use
this
end
well,
unless
I
had
that
cap
which
I
lost,
so
it
has
a
hole.
I
couldn't
use
that
as
a
boat
um
and
also
this
was
cut
with
an
x-acto
knife,
so
with
huge,
huge
adult
supervision
messages.
A
Okay,
um
a
lot
of
this
will
require
using
um
a
blade
of
some
kind.
It
could
be
scissors,
but
a
lot
of
times
it's
going
to
be
an
exacto
knife,
which
is
what
I
did
to
get
this
off.
Okay,
I
use
this
because
almond
breeze
is
a
liquid
and
so
it
hold.
This
can
hold
liquid
if
it
holds
liquid
it'll
be
a
good
um
material
for
a
boat.
A
You
look
around
your
house
again.
Ask
first,
but
look
around
your
house.
Maybe
there's
some
other
things
that
you
might
be
able
to
find
that
could
be
a
boat.
This
was
um
this
was
a
package
for
some
for
something
I
don't
remember
what
it
would
make
a
cool
boat.
It
is.
It
is
this
kind
of
thin
plastic.
A
I
can
imagine
that
being
a
boat,
um
this
is
a
take
a
takeout
container
or
a
like
a
microwave
meal
container
that
could
be
a
boat
all
right.
uh
What
else
do
we
have?
That
could
be
a
boat?
Oh,
I
have
just
this
cap
this
cap
to
something
could
be
a
boat
or
more
like
a
raft
right,
but
it
could
be.
It
could
move
by
a
balloon,
so
you
can
use
lots
of
different
things.
You
don't
want
it
to
be
too
heavy.
Remember
because
it's
just
a
balloon
moving.
A
It
could
be
a
big
balloon,
but-
and
that's
one
thing
you're
going
to
experiment
with
is
is:
is
the
mass
or
the
weight
of
the
of
the
boat
makes
a
difference?
um
If
you
want
to
experiment
with
which
boats
go
fastest?
This
is
a
bottle
here.
um
You
could
use
the
bottom
of
this
bottle.
I
was
going
to
actually
just
cut
this
to
show
you
that
so
here
is
where
an
adult
is
needed
to
cut
the
bottom
of
something
off
all
right.
A
A
A
A
A
So
what
we
use
for
the
um
balloon
and
for
the
motor
of
the
boat
is
a
bendy
straw,
okay,
and
why
the
reason
why
it's
bendy
is
because
it
needs
to
either
point
in
one
direction
or
the
other,
because
it
has
to
let
the
boat
it
needs
to
um
have
the
boat
go
in
the
opposite
direction.
Remember
the
um
equal
and
opposite
from
before.
When
we
were
explaining
newton's
laws,
every
action
has
an
equal
and
opposite
reaction.
So
it's
coming
out
there.
A
So
then
the
boat's
going
to
go
moving,
so
it
does
need
to
go
under
the
boat
and
stick
out
at
an
angle,
and
if
we
used
a
straight
straw
that
would
just
go
down
below
and
if,
if
it's
going
through
the
boat
and
only
facing
down,
where
is
the
boat
going
to
go?
If
it
goes
down
like
this,
I
mean
it
doesn't.
Have
it's
not
strong
enough
to
push
it
out
of
the
water,
but
it's
certainly
not
going
to
go
anywhere.
It's
just
going
to
stay
there
we
may
maybe
it
will
spin.
A
A
The
straw
here
on
the
front
or
the
back,
whichever
way
you
want
it
to
be:
okay,
like
that
and
then
you're
going
to
put
the
balloon
on
the
top
so
that
when
you're
blowing
it
up
you're
going
to
blow
it
up
like
this,
the
balloon
is
going
to
get
bigger,
you're
going
to
hold
the
balloon
and
then
put
it
in
the
water.
Let
the
balloon
go
and
then
like
that.
Okay,
that's
just
a
way
to
do
it
without
having
to
go
through
the
boat.
A
This
one
went
through
the
boat
and
when
you
do
that,
when
you
do
make
things
go
through
the
boat,
you
are
making
a
hole,
and
so
you
need
to
you
need
to
make
that
a
tight
seal
and
one
of
the
ways
that
you
can
make
the
seal
tight.
I
did
use
glue
hot
glue
around
it
to
keep
it
in
place,
but
I
also
used
this
tacky
stuff.
A
A
It's
this
kind
of
stuff,
and
this
stuff,
you
put-
you-
can
put
around
the
straw
around
the
places
where
the
straw
meets
or
goes
through.
Something
put
this
stuff
all
around
that
part
of
the
straw
and
push
it
in
and
then
that'll
make
a
tight
seal
so
that
air
won't
escape,
because
if
this
air
escapes
here,
it's
not
going
to
all
come
concentrated
out
there,
okay.
So
this
is
where
I
blow
this
up.
A
A
Now
you
gotta,
remember
you
gotta
pinch
the
balloon
before
you
put
before
when
you
putting
it
in
the
water
pinch
the
balloon,
so
that
the
air
is
not
coming
out
until
you
want
it
to
come
out,
so
you
put
it
in
the
water
and
then
let's
see,
will
this
move
and
wiggle.
So
you
can
see
that
the
air
is
moving.
A
So
there
is
air
coming
out,
and
so
that
will
be
your
boat.
So
with
this
one
you
could
decide.
I
don't
know
how
easy
it
would
be
to
make
a
hole
in
the
middle
of
this.
It
could
be.
um
Actually
I
could
try
it.
I
could
do
it
the
way
that
I
did
the
bottle
cap
right
and
take
a
hammer
and
a
nail,
a
little
nail
to
start
and
then
make
a
hole
in
the
center.
A
A
So
this
is
the
batter
nail.
I'm
gonna
wiggle
it
around
wiggle,
wiggle,
wiggle,
okay,
there's
a
little
hole,
but
it's
not
big
enough
to
put
a
straw
through.
I
might
take,
then
some
scissors
stick
the
scissors
in
that
little
hole
and
go
round
and
round
until
it
is
wide
enough
to
put
a
straw
through
okay.
So
then,
let
me
put
it
the
right
way.
The
straw
goes
through
like
this.
A
A
A
This
is
how
you're
gonna
blow
the
balloon
up:
you're
gonna,
hold
it
and
then
put
this
in
the
water
and
let
it
go
and
there
you
have
a
boat,
and
this
is
going
through
the
boat.
Okay,
some
plastics
are
easier
than
others.
This
one
will
probably
be
easy
to
go
through.
If
I
wanted
to
this,
one
is
something
that
I
think
I
got
mushrooms
in
from
the
store.
A
A
A
A
B
A
It
when
it's
not
inflated
is
really
difficult
and
it
usually
ends
up
tearing
the
balloon.
Okay,
so
I
have
it
like
this
and
the
edge
the
air
is
coming
out
there
so,
which
way?
Is
it
going
to
go?
It's
going
to
go
equal
and
opposite
it's
going
to
go
that
way
at
the
same
rate
that
it's
go,
that
the
air
is
coming
out.
B
A
A
B
A
This
so
you're
going
to
take
the
string
to
whatever
string
you
decide
to
use
and
you're
going
to
tie
it
between
two
objects.
Okay,
um
I
tied
this
end
on
what
you
would
do
is
tie
one
end
then
take
the
other
end
and
you
are
going
to
thread
your
straw
or
thread
the
string
right
through
your
straw.
Okay,
this
is
a
back
straw,
so
it's
a
lot
easier
to
thread
the
string
through
I'm
using
the
yarn.
B
A
B
A
Think
about
what
you're
tying
it
to
the
two
things
that
I'm
tying
them
to
the
string
ends
too,
are
relatively
the
same
size.
So
it's
straight
okay,
when
it
shoots
across
the
string.
If
you
were
to
do
something
and
try
to
do
two
different
size
things,
it
will
have,
it
will
slant.
Now
that
could
be
part
of
your
experiment.
It
could
be
experimenting
whether
or
not
it
goes
up
at
the
same
rate.
Does
it
slow
down
as
it
goes
up?
Does
it
go
faster
as
it
goes
down
on
the
slant?
That's
something
to
experiment
with?
B
A
A
A
You
can
almost
hear
it
like
a
guitar
string
so
that
this
shoots,
okay,
it
doesn't
get
stuck
on
a
snag,
as
this
is
um
sagging
glove.
Okay,
so
things
to
experiment
with
you
can
also
experiment
with
the
weight
of
the
rocket
that
you
create.
This
has
nothing
connected
to
it,
but
just
the
balloon.
This
has
a
bunch
of
stuff
because
I
wanted
to
make
it
look
cool,
but
it
was
heavy
and
it
did
not
move
as
well.
So
things
to
think
about
the
type
of
string
you
use.
A
What
materials
you
make
your
rocket
out
of
the
size
of
the
balloon
makes
a
difference.
The
angle
of
the
string
might
make
a
difference:
okay,
so
that
is
how
to
make
a
balloon
propelled
rocket.
Another
way
to
make
um
a
propelled
rocket
is
not
to
have
it
on
a
string
at
all.
If
you
were
to
take
the
balloon
and
just
attach
something
to
it
and
have
it
get
propelled
into
into
the
air,
you
can
do
that
too.
