Q: Any suggestions as to where I can find (or how to make) a non-toxic, opaque black goop or slime?
I need about 500 gallons for an installation I’m working on and it involves three people submerging themselves in the “tar” like liquid.
I’ve looked into non-toxic tempera paint, making a mixture of cornstarch, water, and activated charcoal, and pure pigments (most of which I’ve found are extremely toxic).
A: I’ve had good results with Sodium Alginate
It’s a seaweed-based thickener, that’s also dyeable with food coloring or thinned-out acrylic paint.
You’ll need to use an electric mixer and hot water to get it really dissolved, but it’s food-safe, not very sticky, and safe to put down a drain.
You can get it at most food supply places or through Dharma Trading Co.!
They’re located in NorCal, and can ship rather quickly if you call them.
