them by of my ipod
a whole week since I've been on fire but

not today is a new day you been
fine even a you know I talk to the kids

about
energy it's hard to teach kids about

food having energy
sometimes and so I wanted a

demonstration will show this in this is
a classic it's the gummy bear

demonstration
and what we have here is a we have power

that's been turned into a liquid you'll
see I'm using the blowtorch we have to

tailor
years you don't do this at home hope the

seven so if you don't mind
this is a parity away from here this a

powder called potassium chlorate
is alright matter close to the player

hits they wanted
Colbert ass inquiry similar to that

whites the it's on the in the match you
know there's a red no white something

that's on the matter after
so this is a strong oxidizer meaning we

look we'll fight like this it's ready
for any organic to go inside and we're

gonna call the gummy their own organic
you know at your big runner you know

that you carve up before you run
right to gummy bears over here and you

can take a look at the gummy bears make
sure they're OK
after getting a car just a regular old

gummy bear to inform a lot of energy
hi to use it we're gonna do is Emma with

the gummy bears down inside here
now want to watch what happens: races I

intact back if I were you I would rate
gummy bears go down owners abode equal a

true man my mentor
energy that's given of fired a amazing
now look the fire shooting out here like

all of this
energy being released by the gummy bear

it's almost like Jet Propulsion
that amazing so when you teach some kids

that carbohydrates have a lot of energy
it's just the perfect fuel
for this oxidize that's what they look

like when I even
but how you can run a little bit oh my

gonna smoke that's going to the trees
not a big deal at all
look at this war this is one that leaves

practiced with you this one's a call
once you can taxes when
look at the flask you can really see the

reaction it happened once I have been so
there's the chemical reaction
it takes place inside to literally

release that it serves as a fuel
a strong oxidizer like that all you have

experienced the theme is screaming gummy
bear lamp
I had no idea and who is this this

powder with with the
would have protested what we would call

it has imploring disaster is a strong
accent that something that they had a

mystery teachers using the classroom in
this is a classic in the chemistry class

who
see a good to bring the speakers of

other people I and our viewers
that happen scenes in my head when I i

that was yeah
on bullets its instant its burial

message as soon as it was it wise
gummy worms %uh also good as well just a

good swing I could do it now
get those the gym smells and smell the

you can smell
sure enough sugar is sugar is he a gummy

bear yeah as cuz alarm allies will it's
really complicated
we we're not winning this one up on the

website of course but did you know that
I'll website there has almost 400 videos

in experiments and so forth and his kids
are coming back into school they're

looking to do something to share things
to do all my teachers
policy fascinating
