Scanning electron microscopes
have this annoying tedency of destroying stuff you put in them... ^_^

I had the ambtion of
using molecular beam epitaxy to coat a lve chicken in a thin layer of gold and then used a SEM on the bastard, with a negatively charged mesh shielded photomultiplier to catch the secondary back-scattered electrons.
*Frantically tries to recall which electrons that photomultiplier would deflect. Hmm, he low energy ones, so I think i'm right by saying secondary electrons.

clone your nut before you scan it
then use the scan of one as a rough guide indicative of where hairline fractures are likely to lie on the other, use coordinates accordingly and bobs your uncle.
it's almost too easy....

I would say
that a nut's hairline fractures are caused more by environmental considerations than genetice, meaning no cloned nuts surface would be identical due to chaos theory...

no they dont
they actually translocate them into an alternate dimension

You can disintegrate diamonds
using a high powered electron gun. Blats the carbon atoms straight off. Always wanted to try that.

but if you duck taped an almond
to an atom bomb and blew it up, the bloody nut would still be intact: lesson from this, almond shells are the hardest substance known to man. Crash helmets should be made out of the stuff, come to think of it

Assuming that is true.
Take an atom bomb then, and stick it within a hardened steel ovoid. Place the atom bomb at one locus, and the almond at the other. Blow up atom bomb, Almond is history.
(Basic workings of a H-Bomb, except the other locus has hydrogen at it rather than an Almond)

I bow to your superior knowledge of physics
I will stick to nutcrackers, hammers and welly boot heels again this year, before meddling with explosives on any kind

H-bombs are fun.
The first one they built was on an atoll in the pacific, and was the size of a large house. They evacuated it, and blew it up. They didn't evacuate far enough and a lot of sailors got radiaton poisoning. The atoll ceased to exist, completely destroyed.
I think guy who worked on the maths that made the H-bomb possible topped himself when he discovered what his work into geometric shapes had been used for.
And my final H-bomb fact. They were worried at the time that there was the possibility that the initial fusion of the hydrogen may set off a chain reaction in the atoms of the sea and air, and blow up the planet. So they did it anyway.
I think I got all that right, correct me if i'm wrong. :)
Edit: Coincidentally, the same thing occured with the original atom bomb. They thought there was a chance that setting one off would blow up the world. So they did it anyway.

I put it to you
that this is why I'm a good science teacher...
Hehe.
Edit: I am wondering if I can get away with having the kids design using the chemicals available in the lab, and their knowledge of reactions etc. Landmines, and giving a prize to the most destructive design.
Think I may have trouble getting that past health and safety...
