I also thought about the easiest way to "fill" the Hollow breasts. After I saw the pictures of the burst gel breasts and tried to find out what is inside and why it came to such a damage, I found a way to fill the breasts.
Tests on my Doll were very successful and the touching feeling is also great.
Apparently our dear manufacturers use a superabsorber. These superabsorbers have the ability to absorb up to 300 times their own volume of water. Some bind it permanently, others can release it again. The latter are often mixed into potting soil to increase the water retention capacity.
I got 45g of this stuff and then did some tests. You have to know quite well how much water you add, otherwise you get a crumbly mass. But if you hit a good balance, it becomes a gel-like substance. With my remedy this was the case with a ratio of 1:200. Adding water later is no problem. But it is best to try a little bit around until you have the desired consistency before you fill it into the breast.
To get the gel into the breast of the Doll is then relatively easy. Only before the whole operation one should determine how much volume fits/should fit into the breast. The easiest way to do this is to suck the air out of the breast with a big syringe until you can't get anything more out. Then you have about the volume that fits in there. A rough indication is enough it is only important not to take too much or too little of the super absorber. But a little too little is still better than too much.
You need the following tools:
Syringe at least 100ml (depending on breast size)
blunt cannula with at least 14G. Better 12G or even 10G. Best to buy a set.
pointed cannula to puncture a canal through the nipple
Baby oil to lubricate the canal.
Superabsorbents
Water ^^
Doll lay on the back.
With the thin, pointed cannula carefully prick a channel into the nipple.
Remove air from the Hollow breasts and notice how much that was.
If you have measured a volume of 500ml you need about 400ml water and 2g of the super absorber. If you take less, the consistency will remain more gel-like, if you take more, it will become firmer. As I said, test it before until you like the consistency.
Then insert the thick cannula into the breast and leave it in. Later there is no time to get it in. To make it easier to get it in, smear everything well with the baby oil. If you can't get it in, choose one number smaller. 14G is still ok, but with a 12G it is much easier and you have more time.
Prepare the gel. You should work quickly. For a short time it remains very liquid until it has absorbed the water. This is the ideal consistency for injecting it. This step is not about filling up the whole volume, it is only about getting the required amount of absorber into it. The rest is filled up with water later.
Attach the syringe to the cannula and press the prepared amount into it before the contents become too solid. This is the most time critical step. If it has already become a bit too solid, you can draw up the syringe with some water and shake it all. Then the superabsorber becomes more gel-like again.
Now it's time to fill the chest to the desired weight. If you have measured a volume of 500ml you can now inject the amount of water and wait until the stuff has swollen up accordingly. How much exactly this has to be is completely up to your own feeling and preferences. The absorber develops a bit more volume than the water alone.
You have to be careful not to leave too much air in the chest and not to use too little water. Otherwise you will have a muddy sound when kneading. If too much air remains, the swelling absorber usually prevents you from simply pulling it out with a syringe.
Also here it helps to lay the doll on its back and insert the needle just far enough to inject water without any problems. It takes some time until all the air has moved upwards, but you can feel it quite well. If you then inject some water and suck it out again, you will quickly notice if you have caught a possible air bubble. In my case the air only came out in pieces, but like this
Unfortunately I can't post any pictures about it, because I didn't make any.
What you should be aware of is that your breasts can get quite heavy. If the breasts are really big, the lady may have to wear a bra permanently when she has to stand. I don't think there are problems with D and E cups, but it can be critical.
In summary, I must say that the vibration behaviour has improved.Also, the feeling of touching is better and the breasts don't sound so hollow anymore when you give a fold.
On the subject of which superabsorber:
I have used one for terrariums. It was the easiest to get and is quite fine. There are also some for horticulture, although the one is a bit coarser.
Anyone who tinkers with his doll is of course responsible for all damage and misfortunes.From water ingress to the skeleton, ripping TPE because of too thick boobs, to explosive decompression, everything is on your own.
