Well, the short answer is fire performance art. Think poi and firestaves rather than fireworks.

Magnesium has a tendancy to raise temperatures to unsafe levels; that said I have tried epsom salts in meths, no visible change though. I'll try CuCl for a shot at blue, but due to toxicity it isn't ideal.

Thanks, 'tis appreciated.

Well, I've tried strontium acetate, as my strontium carbonate did a grand total of sod all, and that didn't work either. Wikipedia indicates calcium chloride to be more soluble than the acetate, and CaCl didn't do anything much, as mentioned.

Copper compounds give good greens fairly easily, but boric acid gives a fantastic green already, and is less toxic than copper compounds (there's some skin contact during use sometimes). This is also why I use mostly ethanol as opposed to pure methanol.

I lack access to any sort of chromium compounds, I believe manganese will result in green as well however? I tried to make iron chloride previously, via mixing iron powder with HCl, but didn't realise that heating the resulting solution while exposed to air would form what seemed to be iron hydroxide sludge. So that was a right waste of time... was hoping it might result in a strong blue.

-tactical bump-

Pyrotechnics time. I'm trying to create a fuel, ideally based on methylated spirits (95% ethanol, 5% methanol), that has a flame colour other than yellow. I've managed to make a decent shade of green via adding boric acid, which as I understand it gives triethylborate/trimethylborate, which works wonderfully.

Now, a lot of articles found via the googlebeast suggest things like potassium chloride for purple, calcium chloride for orange, and so on - this simply does not work. It's possible the flame colouration imparted by the potassium chloride is too similar to the normal pale blue to be noticeable, however the calcium definitively does nothing, unless you literally light a pile of the stuff with a few drops of meths on it, or take a jet lighter to the crystals.

Ideally I'm looking for red, purple and a strong blue, however blue is always a bitch in pyrotechnics so I don't hold out much hope for that.

Does anyone have any suggestions, that they know to work when dissolved in alcohol fuels? Just because something flame tests a certain colour doesn't mean it'll be applicable, sadly.

Nope, Cadbury's Dairy Milk.

I had a dog that ate an entire kilogram bar of chocolate and didn't so much as get the shits. No idea how.

I'm leaning towards suggesting cyanide, but I'm not going to give procurement information out speculatively, I need to know where the hell he lives, it varies wildly by area.

Also monoxide poisoning is likely to kill him, it's an unsafe gas to work with at the best of times, let alone while distraught and with ghetto gear.

>>4019338
Psychopaths wouldn't care about pain/lack thereof.

I'd not drown it though, there are several other ways. Best one depends WHERE THE FUCK THE OP LIVES, if he'd give me a bloody answer I can name the best poison.

>>4018332
All modern antifreeze contains bitrex or similar to give it a vile taste, I doubt any dog would eat it. It also destroys kidney function, not very efficient/humane.

>>4018310
Nevermind narcosis, it'll work via suffocation. Dry drowning. The easiest/cheapest method would be carbon monoxide, but there's a very high chance of offing himself with that too, so I won't suggest it.

Still waiting for OP to tell me roughly where he lives...

OP, what country are you in? Available poisons vary greatly by region.

And yes, I did go back later on, wall was unchanged. They actually ran out of ink on another wall further in the building, but that was just random crap, not meaningful.

It felt like it was an emo girl who did it, although can't quite say why specifically.

It's worth it, just take good shoes, strong trousers, and a good torch. Gloves and a dust mask can be advisable too - and obviously a camera if you want to document it.

This is one of the stranger things I've seen while exploring... had other graffiti around saying 'I died here'.

>>3772792

Then you sir, are a wanker. There are so many abandoned white-wall buildings like offices, factories etc, this is a form of art set in stone, not a canvas.

This is one from a factory I've been to, the whole site is very well graffiti'd... can't find the photo I was looking for though.

>>3772763
Bit of both... I don't have access to all the photos at the moment, but some lab pics are here: http://www.imagebam.com/gallery/ox6r0pab1aym1si4hzogjq928ei87r0q

Green Oval had the entire saga, but has now lost all the images ... chanarchive had some of the threads: http://4chanarchive.org/brchive/dspl_thread.php5?thread_id=1063134

Last spider photo.

And again. Sadly the light washed out the stained glass, this looked a lot better in person.

One of the many, many spiders.

>>3772736
Had to respond to an email.

Final photo that's worth posting, some more of the outside. The heat melted the lead holding the window in place...

Any questions or more photo/detail/zoom requests, post and I'll see what I can dig up.

The 'Lab Raid' saga, five or six threads about a year ago, detailing my exploration of an abandoned science lab and factory complex. It was an excellent joint effort, with /sci/ identifying the equipment worth salvaging, and directing me where to go on my next trip there.

There was no attic, not even a belltower. The bells are mounted in the outer wall above the main door, and pulled by ropes inside.. sadly the ropes had burnt away, otherwise we'd have given them a good ringing before we left.

This is the outside roof, the huge dent is above what transpired to be the boiler room. Slightly cropped to remove a line of cars.

A door that technically survived, but was charred to a crisp.

I met those criteria at one point. Just find girls with common interests - socialise within semi-rigid settings, such as those of a club or interest group. Less to worry about, and instant shared interest.

The view down the west side of the church, taken from next to my entry point. The other wall safe is to the right of me, out of the picture.

Interestingly, when I first looked through the window, it appeared that there was a lit candle on a table at the end of the church. Obviously now, I know it to be a coke can on the font, and the red light was simply reflected sunlight, but at the time it looked rather uncanny.

And I have no idea about the chair, so don't ask.

The view from the pulpit.

>>3772592

Head lamp, several torches, and dust mask.

The pulpit survived the inferno, I missed this previously due to my direction of travel.
