Hi folks,

I’m looking for a material for a prototype. Properties needed:

-pliable like play-doh or bread dough, so it can be kneaded
-never dries out (or at least not for a few weeks)
-non-toxic
-stays as one mass (chunks won’t easily break off)
-ideally, as transparent as clear glass
-not unpleasant to touch – not slimy
-can be obtained in hand-ful quantities

Anyone know of such a blob-like substance? Thanks!
