I've ordered some bodyslime to play around with, but I have some things I thought I could ask more experienced members of the community.

How best to dispose of bodyslime?
I know you can dilute it with water and wash it away, but I'm wondering if there's other ways to dispose of it. My septic tank won't keep up with a big batch so I'm wondering if it could just be buried or something?

Also, best way to mix it? I've heard that a paint mixer works well, but I don't have one and thought I'd ask first

Good ways to color it?
Anyone know some bodysafe pigments that won't stain?

Thanks in advance!

I haven't used Bodyslime itself, but I'm sure I heard that it's a guar gum/borax slime. The guar gum slime I played with broke down to almost water consistency once a certain amount of extra water was added, more dramatically than you would expect from just being diluted and thinned. Since the borax is not very concentrated and the guar gum is plant material, I reckon the diluted liquid should be fairly benign if poured on soil or down drains.
