While waiting for some litmus paper for the extraction, I'm going to put the cart before the horse and make a machine!
I don't have any experience whatsoever with vaping any substance, but in wondering what to do with my DMT I've decided to construct and use the Machine. I've got a basic idea of what needs to be done but I'm wondering what orientation is going to be easiest to work with and can't find many examples of The Machine in action. It looks like it is usually used with the mesh at the bottom or side - is there any reason not to have it on top and drawing down like a regular pipe? this would also let me put it down on its base - but I'm overthinking it, better to more or less copy what works. Out of all the machines I've seen on here so far,
Cyb's vinegar bottle Machine is my favourite example; this one is inspired by that, but uses a metal straw instead of a glass stem for the mouthpiece.
I plan to drill a hole at the bottom of a ~150ml bottle (in this case a Frank's Red Hot sauce bottle - I was going to use a Tabasco sauce bottle I'd saved but my wonderful partner put it out with the recycling!) and glue on perhaps half of a stainless steel straw as a mouthpiece. I'll use some mesh to hold some steel wool in the neck of the bottle, in line with Cyb's design. Copper scourers aren't really available where I am. Here's the materials I have so far:

I've given the mesh and steel wool a good burn-off over the gas hob.
I used a 2mm drill bit and 6mm drill bit that I had on-hand to drill the hole with an old handheld drill, rinsing the hole with a trickle every time it warmed up enough to give off steam, about every 15 seconds or so. I broke the 2mm drill bit as it went through the glass and the chuck cracked the glass a little but not overly so, I was able to control the breakthrough with the 6mm drill bit. It took about 10 minutes of drilling. I've had a lot of experience with drilling ceramics but still wear gloves and glasses. The water kept dust to a minimum so a mask wasn't really required.
I used a dremel-like mini tool to smooth off the hole and enlarge it a little for the straw to fit in. I also used the mini tool to cut the stainless straw in about half.
For some reason the mesh seems to hold the wool in place even when it's inverted and shaken, but it can still be removed easily. I wound blu-tack along most of the length of the straw and dropped it in through the neck of the bottle, lined it up with the hole and pulled it through while rotating, then wound some blu-tack onto the other side once the length seemed about right. The mouthpiece flexes a little but stays airtight. I may replace it with a glue later. I made sure to use the original straw end as the mouthpiece tip rather than the cut end. The final result:

The curved straw sticking out a little stops it from rolling too far if put down. I plan to have a tray to drop in into in practice. I won't be able to test it until I've done a successful extraction, but at this point I'm happy with the final product.
The stars keep burning,
Worlds keep turning,
Through joy and pain,
Forever learning.
