[JOH] Hi everyone, my name is Joh, and I work
here at Science Space. Today we’re going
to be doing a bit of a science demonstration
that you guys can do at home. It looks like
magic, but there’s something a little bit
interesting going on here. So first things
first, you’re going to need a balloon, you’ll
need a can, it needs to be aluminium and empty,
we’ve drunk all the coke out of this one.
You’ll also need something to blow up the
balloon, at home you can probably just use
your lungs, we like to use these balloon pumps.
So i’m just gonna blow the balloon up. Now
guys if you find it a little bit tricky to
tie balloons, make sure you get your favourite
adult to come and help you. It took me a long
time to learn how to tie balloons, and get
it right. Still don’t know if I'm doing
it the best way. Now what we’re gonna do
is we’re going to make some static electricity.
You guys may have played with this at home
before. I’m gonna show you, for those of
you who haven’t, what it looks like, and
I’m gonna need some help, so Paris do you
wanna come on in? Paris has sacrificed her
hair for us, so what we’re gonna do is we’re
just gonna rub it on her hair, and you can
see that the hair kind of gets attracted to
the balloon. Awesome. Now what we can do with
all the electricity that we’ve built up
on this balloon, so we’ve kind of made all
of the electrons, so they’re like little
tiny particles that are charged that whizz
around in our atmosphere and everywhere, we’re
going to line those up so we have a negative
charge. We’ve got a buildup of charge on
the balloon, and metals really like that buildup
of charge. So what we’re gonna do is we’re
gonna attract this, and get it to move, using
the electricity that we’ve made on our balloon.
Your hair looks lovely. No wait, come back!
So what i’m gonna do, oops, come back, let
me try that one again. Okay, now this may
take a couple of goes. Nope. Oh, it’s moving!
There it goes, there it goes! And there we
go! Thank you so much guys, if you do try
this one at home make sure that you tag us
on Instagram and on Facebook, we’d love
to see your re-creations. Bye
