I've been experimenting with attempts to create brainwave-like patterns for a while now, and haven't had much of any success until I'd seen this thread. So, thanks to bilythekid for sharing. :thmbup:
Unfortunately, my current camera situation is deficient, so I'm unable to share the results of my experimentation. Also, my experiments were less "scientific", than they were "just messin' around with dyes while somewhat inebriated". Hence, my inability to speak with regard to the specifics, but more so to the generalities that I've experienced.
i think we need to find a different carrier of the dye, and also i think i need to re-evaluate my dye mixture.
Something I've had moderate success with, and I've
read about here before, is fumed silica. It's difficult to work with, as it's a superfine powder that tends to fly all over the place with exposure to the gentlest poof of air.
The way I work with it, I leave all of the fumed silica in the original bag it was shipped in, stab that bag with a hollowed out pen, put a rubber band around the bag securing it to the pen, then use an empty condiment "squeeze" bottle to vacuum up the powder through the pen. Once the fumed silica is in the squeeze bottle, I just squeeze it out into my Rit/water mixture. I use 4oz jam jars, boil about 3oz to 3.5oz of water in the microwave, add about 1/8 packet of powder, then begin adding the silica and stirring continuously . It's difficult to measure exactly how much fumed silica goes into each batch of dye I've made. You can make the dye solution just about any consistency from dish soap (and thinner) to toothpaste (and thicker). I haven't played around with it enough yet to test the whole array of consistencies. I just keep adding until I get somewhere between dish soap and toothpaste. If it gets too thick, add water. If it gets too thin, add silica. As long as the 4oz jar doesn't begin to overflow, the powder dye Should still be concentrated enough.
mine failed. the shaving cream dried up too quick and i dont think my dye mix was strong enough. so i did it up more and will wait and see
I think the early drying may have caused such a weak effect. I think instead of a dehumidifier or heater, there may need to be something more along the lines of a humidor. Something that can keep the dye solution moist during the dyeing process. I'm been trying a method where I "steam" the disc. Put it in a pyrex pie dish with a little bit of water, put a lid on top, then float it on top of some almost boiling water.
I'm not sure whether this will aid in your efforts, but thought it'd be good to share. And I'd be curious whether anyone else who has tried any of these methods may have similar experiences.
