Many years ago when I was a teen or younger (50's), there was an article in some magazine about a substance they called Lazy Slurry.  I have checked Pop Mech and Pop Sci but no joy and Google brings up nothing.

I bought some of the chemicals to make the stuff but never did; I suppose because I was missing one of them.

The stuff has properties that are irresistible to the curious and I still want to make some.

At rest it is about like heavy cream but when stirred up or rolled into a ball, it gets hard enough to shatter when dropped to the floor but then reforms into a puddle of cream.

To this day, I know of no material with these characteristics and am hoping someone here might have some ideas.

The only possible clues I can offer may be false leads but there is a bottle of Zinc nitrate from that era in my chemicals and I recall but have since disposed of, a large container of some white powder possibly Calcium something or other.  I think these were purchased for the LS project but would not bet my life on it.

Not that it answers directly your question, but it definitely should give you some keywords to look on:

Thanks for the links.  I guess it's out there and I learned a few new words.

Still looking for the recipe.

I saw the same article around 1952/53' One of the components was Calgon.
The properties were similar to a product called D30 and reported in UK newspaper The Daily Telegraph 19th August.
