Hello, My name is Leonie and I am director of Amazelab.
We are so excited
to be taking over the North Star social media accounts!
we have got so many science from home experiments
that you can all be doing
for this experiment
we are going to be looking at Chemistry
and chemical reactions
to follow along at home you will need...
some baking powderer, some bicarbonate of soda
you are also going to need
some white vinegar
now any vinegar will do
but if it's white vinegar you will be able to see the reaction better
you are also going to need seven clear containers
but if you do not have seven
do not be concerned
do it with as many as you have
you are also going to need food colouring
so food colouring
again any colour you have at home
or ideally in the colour of the rainbow
so today we are going to demonstrate exploding rainbows
now given it's name it can get quite messy!
so please make sure you have adult permission
you have got a protective sheet down
or in fact take this experiment outside
because we are also using vinegar and it can get quite smelly!
so what do you need to do in order for you to explode your rainbows?
the first thing you are going to do
is add two teaspoons of bicarbonate of soda
to your clear containers
so you are right this is just baking powder
that you can find in the cupboard
at home
now it will depend on the size of your container
to have much bicarbonate of soda you need
a small amount should provide the reaction
but again if you are using a slightly larger container
than I am
maybe up to four teaspoons
make sure you are asking adult permission
and we are not just taking any of this equipment out of the kitchen cupboard
but you will be able to find it all in the kitchen
and ingredients around the home so that everyone can have fun and join in
once you've added
your bicarbonate of soda
into your clear containers
you are then going to start creating your rainbow
so we are going to need food colouring
in the colour of the rainbow
so I am going to start with red
so two drops of each colour of the rainbow will do it.
so remember it  is red, orange, yellow, green, blue
some indigo
mine's bit more pink though because it's the food colouring colours
that we could get
and violet
in this experiment we are
going to form a chemical reaction
and that chemical reaction
is going to be between the bicarbonate of soda
and the vinegar
so I hope that you are all watching
really, really carefully
because this reaction is going to happen
really, really
quickly
as soon as I add my vinegar
into my clear containers
the exploding rainbows
are going to start
so are you ready?!
I hope that you are watching
off we go!
let's start exploding our videos!
look at that!
now what is happening
and what is causing our exploding rainbow
is carbon dioxide gas
as our bicarbonate of soda
and vinegar react
they release carbon dioxide gas
the carbon dioxide gas
really, really quickly
runs out of room
in our small container
so it explodes
over the top
so as you can see
we now have an exploding rainbow
in front of us
I hope that everybody
really enjoys exploding rainbows
at home
don't forget to share them
