| For the DNMC nazis -- yes. For reasonable people, either qualifies ... :-) |

The vast majority of a humanbeing is water, so that has oxygen and hydrogen covered as well. ;-)
If we take it as it has to be a pure elemental substance, the challenge is then moot.
24 carat gold is only 99.99 percent pure. It is almost impossible to get an absolutely pure sample of any element. There are always small impurities that creep in.
But at the same time, I don't think a picture of a bucket of water, saying Oxygen, would likely do well. |

carbon based, and carbon are two different things. think of it like bread is flour based. bread isn't just flour. it's got other things that are mixed with the flour to make bread.
although carbon might be one of the easier elements to find at your local variety store.

I have a few ideas for this one, its certainly an interesting one!!
My husband disallowed my "Wow, mercury could make some cool shots" suggestion. Something about it being highly toxic & absorbed through the skin ; )
I would love to have access to Magnesium as I remember at school watching it whizz round a tub of water on fire (think its magnesium anyway). Sadly not something you can buy in a supermarket |

I think that's sodium...very unstable, oxidizes very quickly.

Sodium and potassium both react violently with water. It is very atypical for a science teacher to use Na and K in demonstrations.
Magnesium is a bit less prone to 'excitement' but it does still react with water. Magnesium is much 'safer' to handle in chemistry demonstration labs. It will still react with ignite in water as small shavings but a bit less energetically. |

so we were diddled out of a superb reaction then by using the safer option?! aww now im annoyed - i always wanted something explosive to happen in chemistry!
Still, not going to be able to get hold of any of them for a shot.
I have my shot planned now though, albeit a slightly less reactive one! |

Wonder if we're gonna see any breast shots for "silicone"
:P |

Someone actually did..in the very first post in this thread in fact. And a very beautiful one too. You can click on it to enlarge it.

| Silicon is an element -- silicone is a compound. You might get away with using a computer chip though. |

My 9th grade science teacher had a chunk of elemental sodium he kept in a jar of kerosene, I think. He scraped off a small piece and dropped it in the deep sink with a 1/2 inch of water. VERY interesting reaction...especially from the class.

Some kids at Purdue found some sodium and decided to drop it down the toilet to watch it explode...when it didn't do anything after like 10 seconds they were like "forget this" and flushed it. It didn't turn out very well...lol |

After all these ideas don't forget the lead, Brightness/contrast hue/sat very interesting. :(:(:(:(:)

That true? Sounds like an urban myth to me *cue Twilight Zone theme* |

I think the challenge should stop entries now. It's the only way I'll ever see a top ten entry :)

My lenscap has a nano-particle carbonite film on the inside. How about a photo of that??? It would have to be taken in absolute dark to fully appreciate the texture of the finish.
Actually the challenge should have been capped at 117 entries, the number of elements in the periodic table. |
