Hi, I'm Ricky and this

Keep watching for all this...
How science makes
fireworks go with a bang.
Plus the coolest ride to
the bus stop ever...
First, some of the world's most
endangered animals including
leopards, wild bore,
chimps and golden cats have been
captured on camera in Nigeria.
Take a look at these...
Caught on camera in the remote
forests of Nigeria's largest
national park. Red river hogs. The
Golden cat. This is home sue some of
Africa's most endangered animals.
Conservationists are using hidden
cameras to monitor them.
through a lot of camera images and
it can be quite a tedious process. A
leaf blowing in the wind and you
don't see a great deal and then you
will get a gem like a Golden cat.
Perfect shot and you are handling
and you were not sure they were on
site and there it is in detail.
Chester zoo researchers are working
with local park rangers to help
protect wildlife. This park is home
to a rare breed of chimp found only
in Nigeria and Cameroon next door.
With just a few thousand left in the
wild, these pictures raise hopes the
great ape can avoid extinction.
Over at the Winter Olympics
a 15-year-old figure
skater has won gold.
Alina Zagitova topped the scoreboard

the round robin. We defeated them in
the European final and we have close
games when it comes to the play-offs
We will go away and
regroup for the semifinals and come
back as strong as we can.

Dr Tom has the answer
to an explosive question ?
how are fireworks made?
Dr Tom is an expert,
so please do not try this at home.
Hello, I am Dr Tom,
a fireworks expert.
I am here to answer the big question
this week, which is from
Rees in Cambridgeshire
and it is how fireworks made?
A firework is a lot of different
To make colours we add metal salt
to the firework mix.
So strontium salt to get red.
This to get green.
Sodium salts to get yellow.
And to get blue, the
most difficult colour
of the lot, you add
copper salt to the mix.
What you packed into the fireworks
to make it effective are
This is a star.
This will burn the violet
and in the middle it changes
the composition and burns
with silver sparks.
About the size of
a pea and hundreds of
them are in a firework shell.
Black powder or gunpowder
as some call it
is one of the key ingredients.
It has two purposes.
Sometimes to produce
gold sparks of long
duration flowing down
ground and making it look pretty
but more often as a propellant
to shoot a shell into the sky
or to motor a rocket.
Firework sounds like
whistles and screeches are
made from different
types of chemistry.
We press a tiny band of this
composition into the bottom of
the tube and in the rest of the tube
it acts like an organ pipe to
amplify the sound and make
a really loud sound.
This is a firework mortar.
It is what is used to fire
the fireworks into the air.
We have hundreds and
hundreds of these added
together and the shell goes in here.
The bottom part is for the black
powder to propel the shell into the
air and the top part
is full of the stars
making the big burst of
colour in the sky.
Kids at a school in Norfolk have
been told they are not allowed
certain hairstyles. Extreme haircuts
like this one are deemed
unacceptable. The headmaster sent a
letter to parents saying students
not following the rules could be
sent home or excluded.
We want to hear YOUR
views on this one.
Get online and join
in with the vote.
Finally, more news from Pyeongchang,
but not from the snow and ice.
Take a look at how this guy makes
his daily journey to the bus stop.
This is Team GB snowboarder
Billy Morgan making his way
from the Olympic Village
to the slopes in pretty
Team mate Jamie Nicholls caught him
on camera as he pulled tricks
on his scooter on his way
to the athletes bus.
He goes in the final
of the Big Air tomorrow.
With balance like that
he's sure to win gold!
That's it for now.
