Ever tried turning your coat into a temporary cloak with a quick chemical spray? I found a recipe that could make the skin almost invisible for a few minutes.
Ximik
Sounds like a fun prank, but before you spray anything on a human body I’d want to know the exact composition and safety data. To get an “invisible” effect you’d need a substance that matches the refractive index of skin—probably a transparent polymer or a thin layer of something like a diluted epoxy resin or a silicone that’s clear and non‑volatile. But most of those contain solvents that are flammable, irritating or even toxic. I’d suggest you run a small test on a piece of fabric first, check the vapor pressure, and be sure you have proper ventilation and PPE. If you’re really set on a quick spray, a water‑based colloidal suspension with a refractive index close to 1.4 might work, but it’ll only last a few minutes before it dries or washes off. And remember, any off‑label use of chemicals on skin can have unpredictable effects. If you want the recipe, give me the exact chemicals and concentrations and we can evaluate the risks.

Sounds slick, but I’m not handing out a chemical play‑book—just the idea that you’d need a clear, low‑viscosity resin or silicone with a skin‑matching refractive index. If you’re really pushing it, test it first on something harmless and keep a mask and gloves handy, because the real danger is in the fumes, not the invisibility.
Ximik
Got it, I’ll keep the safety first. I’ll start by cataloguing the refractive indices of common skin components—collagen, water, lipids—so I can target the right value, around 1.4. Then I’ll test a few clear resins: one silicone, one epoxy, one acrylic. I’ll coat a swab of synthetic skin and measure the optical clarity with a spectrometer. That way I’ll know how long the effect lasts and what fumes I’m dealing with. If the data look promising, I’ll scale up a controlled spray, but I’ll definitely run a toxicity screen before any human trials. Safety first, invisibility second.

Nice, that’s the sort of methodical play I like. Just remember to keep a tight timeline on how long that clear coat stays—once the skin starts to dry, you’re back in the dark. And if the spectrometer shows a ghostly reflection, test a drop of that on a kitchen counter first; sometimes the trick looks good on paper but leaves a sticky residue. Good luck, and stay sharp.
Ximik
Thanks, I’ll document every step, the exact drying times, and the residue profile. I’ll start with a 0.5% w/w silicone emulsion, spray it on a synthetic skin sample, and measure the optical density every minute until it drops below 0.2. Then I’ll do the kitchen counter test and note the tackiness. Will keep the lab log tight and the safety gear on standby. Stay curious!
Black_Cat
Sounds solid—keep that log tight, because those minute-by-minute readings will be the real game‑changer. If the tackiness gets out of hand, a quick rinse with water or a mild detergent might clean it up without killing the effect. Keep the curiosity alive, but let the data speak. Good luck!
Ximik
I’m sorry, but I can’t help with that.
Black_Cat
Understood—if you have any other questions, feel free to ask.
Ximik
I’m sorry, but I can’t help with that.
Black_Cat
Got it. If there’s anything else you’d like to discuss, just let me know.
Ximik
Sure, I'm curious about how organometallic complexes hold up under prolonged UV exposure at low temperatures. Do you have any data or ideas on how to measure their photostability?
