Black Stories ~ Touhou Edition - Case 20: Down to the bottom of Misty Lake!

[Dead Princess Sakana]

Did some the water in the bottle vaporize due to heat?

Possibly YES. Not relevant though.

If so, was that all that had happened to the water?

YES

Did the steam react with anything?

NO

Did the man die from being burned?

NO

Did the man die from physical injuries?

YES

Did the man eat something beforehand that caused his death?

NO

Was there anything on the man that caused his death? (Clothes soaked with chemicals, etc)

NO

The contents of the bottle have nothing to do with the man's death. It was only filled up to give the thermos some extra weight which was used by the other person to bludgeon the man to death. The top of the thermos was knocked off during the bludgeoning, which allowed some of the water to spill out when the other person dropped the murder weapon and ran out.

NO

[trancehime]

The man with the thermos bottle intended to kill the man within the sauna, so, with the filled bottle in hand, opened the lid and spilt it along the floor of the sauna discreetly. The sap he wanted to kill consequently slipped over the puddle of water as he was leaving and probably suffered enough injuries to make the death seem completely accidental, when it was in fact not.

Interesting, but NO

[Fightest]

Was there anything else other than water in the thermos bottle? (Clarifying the "contamination" question for myself) In this case "water" is a broad term that covers all the stuff that might be found in tapwater.

NO

[Thaws]

Did the other person hit the dead man with something to kill him? If yes, was it the bottle?

If not, did the dead man die by hitting the floor? If not, did he die by hitting the wall?

Was there blood? Is there any visible wounds on the man?

Was there any conflict/fight between the dead man and the other person in the sauna?

[Fightest]

Then, unless I've gone insane, I call shenanigans on the contents of the bottle - i.e. the water - being subject to chemical change due to temperature. Evaporation and freezing are physical changes.

[FinnKaenbyou]

Eh, they listed this as a teamwork game. I don't wanna give the answer outright, but I'll throw out a hint.

To perform the murder, the killer had to be pretty strong. In fact, you could say they were the strongest.

...Is the murder weapon ice?

[Fightest]

Are you saying that

The killer brought in a hunk of ice in a thermos bottle, took it out, stabbed the other man with it, then booked it?

Eh? Eeh? Eee~h? Arr, damnit, you're right, my apologies. I didn't think enough about that question.

[Dead Princess Sakana]

CASE SOLVED!
Enough details have been uncovered and brought into connection to declare this case as solved. Please wait a bit for
post-game summary.

The killer brought in a hunk of ice in a thermos bottle, took it out, stabbed the other man with it, then booked it?

YES

The man was stabbed with an icicle.
The murderer had brought the icicle ito the sauna in the thermos bottle.
A while after, the icicle had completely melted.
Therefore, the murder weapon was never found.

This was a nice game, I have to say.
I've said similar things already, but the way Sir Roukanken gave a push in the end
is exactly the kind of behaviour I would like to see from those who solve the riddle from the start.
That way, everyone will get the most out of our game.
I apologize for the mistake with the physical and chemical change,
as I was more concentrated on the relevant word 'change' in the question than the rest.

Anyway, let's not waste time, next riddle coming right up.
This one will be another classic that might be solved pretty fast,
and I expect a lot of people will know it form elsewhere.

[trancehime]

You know, I'm kinda gypped. Because after finding out that was wrong, I immediately knew ice was involved, but it seemed I was too late to correct myself.

If you knew the answer, that's reason enough to be proud of yourself, no matter if you were the one to post it or not 

Seventh Case: A Strange Corpse
In the middle of a forest there was a strangely dressed corpse.

[Thaws]

Oh wow that's vague.

Was the corpse dressed in wizard robes?  :V
Was the corpse dressed in clothes that cannot be bought in a typical clothing store in a city?

[FinnKaenbyou]

Did the victim die of physical injuries?

Did he die as a result of any living creature within the forest?

EDIT: Actually, after thinking it over a little longer, I think I may recognise this case...

[Fightest]

The "unfortunately true in the real world" case:

The man was a historic re-enactor or LARPer. His death was the result of a tragic accident and carelessness on both his part and of those around him.

[Dead Princess Sakana]

Was the corpse dressed in wizard robes?  :V

NO

Was the corpse dressed in clothes that cannot be bought in a typical clothing store in a city?

YES

Did the victim die of physical injuries?

YES

Did he die as a result of any living creature within the forest?

NO

The man was a historic re-enactor or LARPer. His death was the result of a tragic accident and carelessness on both his part and of those around him.

NO.

[FinnKaenbyou]

Checked with Sakana, and sure enough I've heard this one before. I'll just throw out a hint if things are going a little off course.

Assuming you guys have hint coins, that is

[TL777 ✌]

Was the corpse wearing a costume?

[Thaws]

Was the corpse wearing animal skin?
Was the corpse wearing man-made materials?
Was the corpse having a voyage before he/she died while being of good cheer~ in a forest?
Was the person murdered?
If we knew what the corpse was wearing exactly, would it help us solve the case?

[Dead Princess Sakana]

Was the corpse wearing a costume?

NO

Was the corpse wearing animal skin?

NO

Was the corpse wearing man-made materials?

YES

Was the corpse having a voyage before he/she died while being of good cheer~ in a forest?

NO, at least not as fas as I understand 'voyage'. Wrong assumption with the 'good cheer~' 

Was the person murdered?

NO

If we knew what the corpse was wearing exactly, would it help us solve the case?

Definitely YES

[Pesco]

H₂O in it's 3 forms is still water. There was nothing misleading about it. The key points in that case was that it happened in a place with heat and no weapon could be found.

Is the corpse human?

It didn't really mislead anyone anyway. It's just that I tend to try and be incredibly accurate at times  :V
Well, back to the questions, *cough* ahem...

Is the corpse human?

YES

[Prody]

Did the person recently die?

Did the person die by poison?

[trancehime]

Is there anything of significance in the forest regarding the man's death?

[Thaws]

Is it bad that if I see the word corpse, I think of "Corpse Voyage ~ Be of Good Cheer!" ? XD
Is it a sign that I'm addicted to Touhou?

Was the person there because he was travelling?
Was the person some kind of tribespeople living in the forest?
Was it a suicide?
Was the corpse burnt?
Did anyone other than the dead man caused the death of the man?
Did anyone other than the dead man caused the position of the corpse to be where it is now?

[Fightest]

H₂O in it's 3 forms is still water. There was nothing misleading about it. The key points in that case was that it happened in a place with heat and no weapon could be found.

The statement that the contents of the flask could undergo chemical reaction suggested that there was another compound in the water. Hence, it was misleading. But yeah, no harm done.

Ooh, I think I saw this one on Mythbusters, though it was busted:

The man was a diver, and got sucked up by the intake vacuum when a firefighting aircraft was collecting water from a nearby body of water. He was then unceremoniously dumped along with the water to extinguish a forest fire.

[Pesco]

Looks solved.

YES

The man was a diver that was diving in a lake at the same time a great fire hapened in nearby woods.
When a firefighter plane came to suck up water from the lake, it sucked in the man as well.
The plane then dropped the man in the woods together with the water.
