dealing with matter in the scientific sense, there are four kinds or states of
- 00:37
matter that you'll need to know we'll start with gas, so that we can get all
- 00:42
the giggles out of the way the particles in a gas are very far apart and are [Particles in gas and children play]

bouncing around like a class full of kindergartners who just ate too many

strange and unpredictable ways and while we're on the subject air itself is a gas
- 01:00
yep, that lovely oxygen you use to fill up your lungs on a daily basis while that
- 01:06
stuff's the definitely gaseous which is a relief because if we had to breathe in a
- 01:10
solid in order to survive when we'd be insanely congested when the particles [Man breathing in rocks]
- 01:15
are much closer together, still free to move around but somewhat constricted
- 01:19
like an elevator that's nearly filled the max capacity you've got yourself a
- 01:23
liquid and when the particles are super close together to the point where
- 01:28
they're barely moving at all like the stuff on the top shelf of your fridge
- 01:31
then you've got a solid while we're thinking about it this might be a good [Fridge opens]

pretty sure milks seen better days but there's a fourth state of matter and
- 01:42
believe it or not it accounts for over 99% of the visible universe plasma [Plasma in universe]
- 01:47
consists of free moving electrons and ions and can be found in everything from
- 01:53
neon lights to lighting to yep you guessed it plasma TVs but gaze up into
- 01:59
the night sky and you'll be looking at a whole lot of plasma even if it is a bit [A couple staring into the night sky]
- 02:04
out of reach all that star stuff is made largely of plasma or ionized gas and
- 02:09
those are your four states of matter watch out for those guys in the white [Man in a park chased by men in white suits]
- 02:13
suits with a big net you want to avoid them if possible
