00:00:12.799 --> 00:00:18.480
i'm painting mars my favorite planet did

00:00:16.480 --> 00:00:20.320
you know that it's red because it's hot

00:00:18.480 --> 00:00:22.960
well

00:00:20.320 --> 00:00:24.720
mars isn't red because it's hot

00:00:22.960 --> 00:00:27.840
let me show you what i mean

00:00:24.720 --> 00:00:30.960
mars surface is made up of rocks

00:00:27.840 --> 00:00:33.920
now all these rocks are full of iron

00:00:30.960 --> 00:00:36.960
when the iron oxidizes the rocks turn a

00:00:33.920 --> 00:00:39.200
reddish rusty color

00:00:36.960 --> 00:00:41.600
that's why the surface looks red

00:00:39.200 --> 00:00:44.559
then when the wind picks up these rocks

00:00:41.600 --> 00:00:46.000
and dust the atmosphere turns a pinky

00:00:44.559 --> 00:00:47.680
reddish color

00:00:46.000 --> 00:00:50.399
that's why from earth when we look at

00:00:47.680 --> 00:00:52.000
mars we see it looking the color red

00:00:50.399 --> 00:00:54.320
here's a quick science experiment that

00:00:52.000 --> 00:00:55.760
you could do at home or in the classroom

00:00:54.320 --> 00:00:57.760
to create rest

00:00:55.760 --> 00:01:01.600
all you're going to need is 200

00:00:57.760 --> 00:01:01.600
milliliters of hydrogen peroxide

00:01:02.399 --> 00:01:06.640
150 milliliters of vinegar

00:01:06.880 --> 00:01:10.799
and 25 milliliters of

00:01:10.840 --> 00:01:15.200
salt then you're going to need any piece

00:01:13.200 --> 00:01:18.000
of metal that you like i'm going to use

00:01:15.200 --> 00:01:18.000
multiple pieces

00:01:19.840 --> 00:01:23.840
now once you've mixed and dissolved your

00:01:21.920 --> 00:01:28.479
salt you're going to want to wait 20 to

00:01:23.840 --> 00:01:28.479
25 minutes and watch your rust form

00:01:31.140 --> 00:01:36.479
[Music]

00:01:33.920 --> 00:01:38.880
look at that you've created rust now

00:01:36.479 --> 00:01:40.560
although this isn't exactly

00:01:38.880 --> 00:01:42.240
the surface of mars

00:01:40.560 --> 00:01:43.040
it's still a great experiment to show

00:01:42.240 --> 00:01:45.600
you

00:01:43.040 --> 00:01:48.079
why mars is red now back to charlotte

00:01:45.600 --> 00:01:49.759
for a real world example think of it

00:01:48.079 --> 00:01:51.600
like this

00:01:49.759 --> 00:01:54.399
what happens when you leave your bike

00:01:51.600 --> 00:01:56.159
outside for a long time it rusts

00:01:54.399 --> 00:01:58.320
good it rests

00:01:56.159 --> 00:02:01.600
that's sort of what's happening at mars

00:01:58.320 --> 00:02:04.000
so mars isn't red because it's hot

00:02:01.600 --> 00:02:09.200
it's red because the iron rich rocks

00:02:04.000 --> 00:02:13.560
oxidize and turn a rusty color exactly

00:02:09.200 --> 00:02:13.560
mars really is the best planet

00:02:14.360 --> 00:02:17.689
