Is this an engineering problem or what?

Two of the buckets I use around the garden, etc. are stuck, one inside
the other. I and other neighbors, strong ones,
have tried like hell to separate them. Thumping, prying, banging, even
pouring water around the rim of the bottom one.
Nada. Niente. Nichts. Rien.

This has become a challenge.

What next? Baby powder? Or...?

Baby powder? Does it have a rash?

A picture would help.

I'd be looking to attach a clamp or vise grips
to each and then use the attached parts to gain leverage.

If you can pour water between them, fill the gap and put
the whole thing in the freezer.
