i'm painting mars my favorite planet did
you know that it's red because it's hot
well
mars isn't red because it's hot
let me show you what i mean
mars surface is made up of rocks
now all these rocks are full of iron
when the iron oxidizes the rocks turn a
reddish rusty color
that's why the surface looks red
then when the wind picks up these rocks
and dust the atmosphere turns a pinky
reddish color
that's why from earth when we look at
mars we see it looking the color red
here's a quick science experiment that
you could do at home or in the classroom
to create rest
all you're going to need is 200
milliliters of hydrogen peroxide
150 milliliters of vinegar
and 25 milliliters of
salt then you're going to need any piece
of metal that you like i'm going to use
multiple pieces
now once you've mixed and dissolved your
salt you're going to want to wait 20 to
25 minutes and watch your rust form
[Music]
look at that you've created rust now
although this isn't exactly
the surface of mars
it's still a great experiment to show
you
why mars is red now back to charlotte
for a real world example think of it
like this
what happens when you leave your bike
outside for a long time it rusts
good it rests
that's sort of what's happening at mars
so mars isn't red because it's hot
it's red because the iron rich rocks
oxidize and turn a rusty color exactly
mars really is the best planet
