Bucket Design

Its a German thing.... it all started when boots were the only types of buckets available for storing beer in.

So you can stack empty ones compactly, each mostly nested in the one below.

GA, and they won't fall in either do wonder if there is a rigidity thing too per volume and sq foot of sheet metal, but don't know. stacking is good

Easier to wear at parties (one size fits all).

So that the sand doesn't stick when your making castles on the beach.

It may have been, that when the buckets of water froze, the ice would expand up and thus save the bucket from damage.
