Water beads - a bad or good idea?

Water beads are small balls of polyacrylamide or sodium polyacrylate (see wikipedia). This is a harmless substance that absorbs many times its weight in water. They are sold in bulk to put plants in.

Has anyone used them as a means of delectable rectal torment?

I imagine that a little sprinkling of them (a few milliliters) scientifically placed in the rectum would slowly absorb water and expand into a prodigious mass, with attendant discomfort.

I prefer to live a long and healthy life with my colon intact. I would hate to end up in the Emergency Room having to explain that one. In my opinion, it is not a wise idea.

I found this comment on a site about the stuff:

"My nephew put these water gel crystals down the sink drain & now it's so clogged the plumber can't even break it up with a power snake."

Also, it's my guess that these things just might draw the water out of your colon, thereby possibly dehydrating you maybe quicker than you could imagine and would result in dire consequences.

Another quote: "How it works: A little water gel powder converts liquid water to a high molecular weight gel ranging in consistency from a solid to slush, depending on the ratio of water to powder."

I think Petalsoft raises valid points. However, dehydration might not be an issue, as ordinary glycerin (and epsom salts) work exactly the same way. I don't think they adhere to each other, and one would have to be intelligent regarding the quantity for the reasons you give (assume 200x increase in volume). For instance, one cc of water beads leads to a final volume of 200cc of non-adhering balls, which seems pretty safe. But, yes, gradual experimentation seems to be wise.

Incidentally, this is strictly rectum, not colon; swallowing large amounts can definitely be hazardous, at least to infants. But these caveats go for all play.

A quote from the wikipedia article on polyacrylamide: "Polyacrylamide is not toxic. However, unpolymerized acrylamide, which is a neurotoxin, can be present in very small amounts in the polymerized acrylamide,[1] therefore it is recommended to handle it with caution"

Sticking it up your arse does not sound like a very good idea to be honest (and more generally, things that expand uncontrollably inside you are not a good idea - it's easy to get into a bad situation you can't stop until it's too late).

@Apollo - acrylamide has an LD50 of about 150mg/kg, or 10 grams per human, which is a big dose; in fact, it's only moderately more toxic than Tylenol/paracetamol (LD50 of 330 mg/kg in mice). The amount of acrylamide in 100g (a huge amount) of polyacrylamide beads at the stated contamination of 0.05% is 0.05g, about 200x less than the LD50, and very little of this would ever be absorbed from inside the beads. Polyacrylamide is even injected as a filler in facial surgery. So the toxicity issue is highly theoretical; the beads are sold as 'non-toxic'. I'd worry more about jelly toys and pthalates.

As for uncontrolled expansion and 'too late', well, a bit of math and caution go a long way. The beads are regarded safe to swallow, just not too many, and not the big ones, and not by small children. The issue is blockages of the small intestine if swallowed.

I just think this is a highly unsafe and dangerous experiment. I hope anyone reading this will use CAUTION and think twice about doing such a thing. It seems we are a glutinous society and people tend to think if a little is okay, then a lot is even better. And, unfortunately, there is a large part of the population that isn't too good at math, and they could be some of the ones that suffer from not being properly informed.

@petalsoft - I guess I'm a little baffled at the fears expressed (though common sense, incrementalism, and caution are warranted of course).

This purely rectal idea is far less extreme than many of the things I read about here, like penetrations far up the colon, rib-tickling fisting orSwitchablesusie's brutal glycerin and Bonner's soap enema recipe .

I guess that I am just fairly cautious about sexual experimentation in this manner - the thrill of the moment can easily lead one to exceed limits one would not exceed when acting calmly and logically. That also goes for the other ideas you mention, none of which I would be willing to try personally. This attitude stems from having some near misses in the past (when I was much younger and stupider than either you, or myself now) - once giving myself an impromptu rectal biopsy by inserting something with sharper edges than ideal, and once damaging my foreskin to the point of slight scarring with some overeager play.

I concede that you've done your research on the toxicity question (assuming that no chronic toxicity effects occur at significantly lower doses to the acute effects), but I would say that if you are going to try this, and I would still strongly advise against it, you need to be extremely careful with quantity, as you acknowledge. I'm not certain how wide the window is between discomfort (which you state you are aiming for), and damage (which I believe you are not). I don't think one can get a very good idea from the size of balloon enema nozzles etc. as the beads would be free to move up, rather than just outwards.

This sounds like the material a toy that was recalled this past year was made from.

This "toy" that you submerge in water expands tremendously when hydrated. Children have swallowed these since they are colorful and looked like candy and they have caused intestinal obstructions requiring surgery to remove. I would stay away from this.

Not to lose sales, the company has changed the use for the product to be colorful plant substrates. http://www.magicwaterbeads.com/

I don't want a lot of marble sized spheres clogging up my colon. In their website that state ". . . . Never flush or pour them down the drain, as the swelling could possibly clog drainpipes."

@switchable - yes, children have swallowed the large beads ('Water Balz'), and it has lead to obstructions of the small intestine. However, perhaps one should emphasize the words 'children', 'swallowed', 'the large beads', and 'small intestine'. The ball expanded to 1.5" in the case of the toddler (see CU link), which is a big risk in the small intestine of a child, but pretty moderate for a grownup toy. Basically, I'm arguing that there are miles of difference between these known hazards, and any grownup activity

I know I must sound like a broken gramophone, but I guess I feel the comments I've been getting represent, well, a 'non quantitative' risk assessment.

Also the second use of the beads (gardening, flower arranging) is independent of their toy use. I don't think that www.magicwaterbeads.com is the same company as Water Balz. They are basically a commodity item.

I respect people who present carefully reasoned logic. I simply cannot respect responses devoid of logic, careful argument, and reason.

Apollo did bring up a toxicity issue, which prompted me to look at it in detail, and do some calculations. I consider his response to be useful and productive, because it prompted to do some thinking that I would not otherwise have done. Switchablesusie offered some instances in which these beads have caused problems. Following her lead, I looked into them in depth, and responded. In both instances I did not agree in the end, but they both made me think, look things up, and do some math.

This is how science works: civil discussion backed by facts and logical argument, without anybody becoming emotionally invested and resorting to emotive language.

What is your carefully reasoned scientific view on the toxicity of unpolymerized acrylamide in polyacrylamide at its 0.05% typical contamination level? Undoubtedly, you've read the link [1] below concerning the toxicity, like "Several 2-year chronic oral toxicity studies in rats and dogs fed diets containing up to 5% Polyacrylamide had no significant adverse effects."

And perhaps you've seen Squish BAFF [2] - again, what is your educated opinion on its toxicity?

You've undoubtedly included the existence of several precedents [3,4,5] of using gastrointestinal or rectal polyacrylates?

OK I concede that "fanatic" is an ungracious and unhelpful swipe. I apologize.

That said, let us all be cautious that erotic musings do not override good judgement. Sex is fun, injuries are not and can endure

This is an interesting concept. If I were going to try it though, I would try a certain amount in a condom first with a specified amount of water inserted into the mix. Measure the maximum girth after the beads have absorbed the water to see if the person trying this can take it. If so, start with a new condom and fresh beads then insert in the willing victim's ass before adding water. Could be fun to feel it stretch you out, could be agony as well.

Found this old thread as (late to the party as always) I just learned about these beads. Bought them on a whim as they were cheap online.

I found a potential solution to the problems discussed here: contain them in a bag which is porous to water but with a weave tight enough not to allow the small unexpanded beads to escape. I tried this today with a piece of nylons and it did work. However the cheap nylons I buy from the dollar store mostly for craft purposes were a bit too rough on my insides. I think a finer weave like maybe silk or higher quality leggings (I have no experience with these so I'll have to go have a feel in a store somewhere) would be preferable.

It didn't exactly have the effect I was hoping for in having hundreds of balls seeping out of my body individually, like in some crazy hentai lol but the feeling of growing something inside was definitely fun. I used a conservative amount of beads but I think this could be scaled up. Also using multiple pouches of beads could be interesting.

Also for the benefit of future over enthusiastic travellers, I will contribute that I tried just shoving them up my cunt (sans bag) but realized that was a bad idea as they could become lodged in the other holes such as urethra, skenes as bartholumeus glands. Luckily I thought of this immediately after I'd done it and checked myself out. Had a very long and unsexy moment where finding it had, I had to dig a tiny object from my B gland with a blackhead tool. Disaster averted. But: don't do that. Getting them in the cunt requires at least a speculum (if done at all... Which I don't think is advisable). You shouldn't be digging around in your glands with grooming tools.

Wondering if anyone can think of a problem with this technique?

Thats why i didnt pursue chemistry

I did some reading on using these beads a few months ago and decided against it. And I do like anal toys and expansion Just seemed to risky

Tried them today. Inserted a bunch of them through speculum and pushed them with dildo - very nice sensations. Then I fisted myself to get all of them out - also nice sensations. Nothing bad happened, I don't think that they can be dangerous.

I've personally tried this… sorta.

I bought a bag of the big beads about the size of my palm when placed in water long enough. after a day and a half of soaking I stuck a few in a condom and tied it off.(avoid any thin/"bare skin" condoms for safety)

Making sure to lube it all up when inserting. The hardest part is getting first one in(even with lube) and after its in the rest just plop in!

The beads sometimes will stay together but most will break as soon as they get inserted.

as long as some of the condom stays in you can keep back up your booty and have em plop (or squelch) out just don't go to crazy, otherwise you might make the condom rip (you will know by an unmistakeable “pop” in your rectum)
