How do you make faux marbelizing on inflated balloons using acrylic paints?

Question

It seems like we took a tub of water and added a suspension agent (liquid starch maybe?) then squirted different colored acrylic paints into the liquid, briefly "swirled" through the liquid with a plastic spoon. Took the inflated baloon and dipped it into the liquid mixture and as you remove it, the "marbeled" mixture adheared to the baloon. I don't remember what the suspension agent is or ratio used.

Answer 1

I've never done it on balloons before, but I'm sure it is the same procedure you use for marbleizing paper. Here's a place that tells you how.
