Finally, after several trials of trying to make sizing that's gonna work.
The first trial was completely a waste of time and material. It was much too thick, I was going too fast, too much. So, that had to be thrown out.
The second trial, I stuck to the recipe I found. 1/2 cup of corn starch and 1 cup of cold water, mixed then pour into boiling water. (of course the recipe I found it said to mix corn starch and cold water in big bowl and pour in boiling water). As it turned out, the damn thing didn't turn clear and it was way way too thick. Since I didn't know how much of boiling water I was suppose to put in.
So, I tried smaller portion of corn starch/cold water. This time it was 1/4 corn starch and 1/2 cup of cold water, into 6 cups of boiling water. It still didn't turn clear like the recipe said, but I found another one that said it might be cloudy, so I guess it's ok.
I left it to cool down, and now I found one that work!!!
So, next step, figuring out how much water and acrylic paint to mix and how much dish detergent to put in. Currently it was a good size acrylic and about 11 CC. of water and a drop of dish detergent. Seems like it was pretty good, but it spread out too much. So it'll be another few trials I guess.
