Stable translucent liquid/goo?

[Bfarn]

Hi all,

I'm working on a project that includes some illuminated parts moving around in viscous, translucent liquid. If this was for a movie or something with limited exposure I would have a lot of options - stirring up stuff into a suspension looks great - but most cloudy liquids settle or separate eventually.

Has anyone got experience with cloudy goo? I'm looking for something like watered down milk, but thicker, and less prone to spoilage. Ideally, though this is less important, I'd love a substance that diffuses light enough that I could change its apparent color with LEDs from underneath.

Thanks!

What about liquid soap, shampoo or hair gel?
KY.
Karo syrup.

Sodium Lauryl Ethersulfate 70% with Water and Salt = Gel. I've made my intern in a soap and detergent company and they told me how they make soap gel.

Ok, you folks are pretty awesome. I knew the answer would be something simple, but that I'd never normally think of.

Liquid soap is EXACTLY what I need. Time to hit up the walgreen's.

Thanks!

You might try methylcellulose, the stuff they use for special effects saliva and slime, with something added for cloudiness. Maybe a bit of acrylic paint or white gouache.
