# Thermit the bastard
thermit it hard!

# Now *there's* an idea.
So what's that then:
Iron fillings, aluminium fillings ... magnesium powder/ribbon?

# Yep
I can't remember the proportions or tell you where to find some though.

# The internet will know ...
It *always* knows (although it's often wrong).

# nah
Fe2O3 + Al = Al2O3 + Fe (molten due to exothemic (negative) enthalpy change)

# Nice
Correct valencies too. I'm impressed.

# If I was a teacher
Marks would be lost for not balancing it.

# ok, ok
Fe2O3(s) + 2Al(s) = Al2O3(s) + 2Fe(l)


nuuhh

# Shit, what was i thinking
Shit, that's embarrasing. I'm a friggen chemist (thus the enthalpy comment), yet I can't balance an equation!

Cheers for the state symbols.

# Yes!
Isnt it iron (iii) oxide powder, aluminium powder, mix into a small pile and stick a bit of magnesium in the top. Place pile on computer. Ignite magnesium. Run.

# You would want it in some kind of crucible
A thick clay flower pot with a hole in the bottom would be an idea.

# Nah
Cuz it'd melt thru the pc into the ground.

If you want to do it alone, i find a coke can with the top chopped off, half filled with sand is good.

# Oh yeah, that's what I want to see ...
The hole all the way through the casing and mother board etc... Just do it on some soft soil that you don't mind having to dig a lump of iron out of :)

Like corrosive alien blood!

Oh yeah, in case it's not obvious ... don't be near this when it goes off (at least not unless you're wearing something that will cope with droplets of molten iron being splashed onto it).

# i'm disturbed by the pyromania round here
(but i'm grinning like a goon).

Magnesium.... ahh, the joys.

Once, at school, a group of us what had done Maths a year early (hey, wasn't my idea!) had a free period (well, we were supposed to be doing Statistics, but come on...) immediately after a Science lesson involving Mg ribbon. What I didn't know is that one of us had snaffled a six-inch strip of it. Which they ignited in the corner of the room we were in for the 'free'.... ouch, my eyes!! And the clouds of smoke that were still very much in evidence when the supervising teacher wandered in ten mins later....

# If you like magnesium
You'll love what it does in the thermite reaction.

It's truly fantastic.
