Please read this, then post and guess away

Excellent. I have a perfect one. (some of you may have already read this in Photo-A-Day though)

So...sky or water?

OOo, I remember that one, lioness, so I will withhold my answer and see if someone else knows it!

I would say sky. Beautiful picture, Lioness

I haven't looked back through the Photo-a-Day thread to find the photo (honest ) but I think it looks so much like the sky that I'm going to say we're seeing 'water', possibly reflecting the sky.

Is it in the southern corner of South Australia? If so, I know what it is.

lol what a great photo. My first instinct is to say it's sky but I can see how it could be water too.

I think it is both...

I will not say a word, but I have been there. Let them stew for a few more hours, I reckon.

I'm guessing its Blue Lake then

Yeah, quogequox, you're right.

It is a lake in Mt Gambier called the Blue Lake. In summer it goes that light light blue, and in winter it turns a more blueish grey.

I specifically took the photo to see how many people I could confuse by asking them if it were sky or water.

So, it is water.

Wow. That is amazing. Nice one, Lioness.

So can anyone jump in now and put up a photo? If no one has by the time the house quietens down tonight I'll do one.

Yes anyone can post a photo. Recommendations can be found by following the link in the first post. That's also the place to talk about 'What is it?' thread. Rather than have rules, we hope to just let it run and maybe only make a rule or two if the thread runs into any problems.

Might be pretty easy but coudn't think of anything that wasn't immediately obvious!

Third time lucky - I'm not sure if it's too big or it's just showing that way to me. Somone let me know

The size is just fine. As for what it is - I will think about it, all I can think at the moment is a lump of lard.

A tooth?

Ah, that sounds about right Martin, it could be Conor's first tooth that fell out last week!

It looks like some kind of reflective mirror. What's the name of the rock that is shiny...hematite?

It looks like a bit of chalk used to mark things off in sewing. We know that Copago has been sewing a few things on her machine (remember when she asked about needle sizes?).

So, my guess would be a piece of sewing chalk.

Yep, it the tooth

Oh Excellent, Copago - did the tooth fairy visit Conor?

Well, I think this is probably quite obvious, but I accidentally took this with my camera phone. If I don't close the shutter, it sometimes takes a pic of it's own accord, and this is the result!

Could it be a C.D?

Yep the tooth fairy came - but Dad had to organise all that as the two of them went camping that night. His second one fell out a couple days later.

I'll agree with the CD too, Slew. Quite an artistic shot for an accident

OK Whats this?

I looks like it might be the back side of a ski lift.

Knowing where you live, mate, I will say that it is the start of a dam on Lake Eyre!

They're damming Lake Eyre???
I would have said the head to a mine?
