I've continued my... research... in multiple directions.
First, durability of the basic, double condom version derived from SAP separated from a booster pad by the "shaker method" is quite good. I haven't had a rupture yet in either condom across my three test models. But separating SAP from diaper fluff creates a lot of dust, so I'm seeking alternatives.
Second, the first alternative I'm working on is prepackaged instant snow SAP. They differ in important ways. The instant slow "fluffs" very quickly in water as might be expected, while diaper SAP forms a mostly contiguous gel. I was skeptical at first that the instant snow would make for a good solution, but it's just a matter of how much water you need to introduce to get to a gel form, not a snow form. As gel, it does create a looser, slosh-ier consistency, which has its benefits. You can still leave it at the snow level and have a softer, more aerated cushion if that's your preference. I'm not sure what the actual differences are between this instant snow SAP and diaper SAP, but
- I assume there is a polishing process applied to diaper SAP that slows the absorption by means of reducing surface area. I came to that conclusion based on the irregular shape of the instant snow gel crystals vs a product like Orbeez, which take quite a lot of time to fully expand. If polished, it would interact with the fluff of a diaper over time to preserve wicking function. In fact, the SAP in these boosters of Bambino/TotalDry make claim a "time release" feature, so I'm guessing that's the way they achieve that.
- The other possibility is that instant snow is polyacrylamide based and diaper SAP if polyacrylate based. I might have to try some of the polyacrylate based powders. They aren't usually marketed as "instant snow" and instead claim to be literally diaper polymer, so they may give me more of what I'm looking for.
- And if you're thinking about integrating Orbeez into the process, so have I. Would you like your shit with a passed corn texture?
Third, I'm experimenting with brown colorations to produce a more poo-like appearance. My first attempt appears to be somewhat successful. I added Hershey cocoa powder to a solution of instant snow powder and water. It makes quite a believable turd, so much so that I don't want my wife to see it, assume I'm preserving my crap in condoms, and have me committed. The only concern I have is that cocoa butter, a fat like oil, will degrade a latex condom, and I don't know how much of the cacao fats remain after the extraction process. I'm currently monitoring the condom for signs of degradation, but all I have at the moment is the pleasant scent of chocolate on my ass. (See Alton Brown's Good Eats episode "Turn On The Dark" for an excellent primer on many things chocolate.) I hope this holds up, because the cocoa powder and the instant snow gel makes for a very nice texture. Whether or not this approach fails, I might experiment with a mica pigment powder for the brown color, which would have the side effect of making my faux-feces sparkle...
The ultimate solution may involve a blend of multiple materials to achieve the perfect consistency.
Finally, I'm working on a list of supplies for a video on making these. I have a distant thought of creating handmade, custom fake turds to your pure squishing satisfaction, and selling them through Etsy, but I think that's far enough off. It would be fun to have multiple custom types, consistencies, latex free versions, and/or any color you want. Want to have cute pink turds because diaper princesses shit pink whipped cream like the unicorns they are? Boom-boom! Done!
And, on a side note... this is my 1000th post on ADISC!!! And it's about fake shit...
EDIT: Just discovered these enormous SAP crystals. Larger than Orbeez and irregular shaped.
