I have a lot of empty 5-gal. buckets, usually from drywall compound, and I stack them up to save space. They inevitably get stuck together, to the point where a lone person has a hard time getting them apart. Holding the bucket stack with my feet and pulling up on the top bucket often doesn’t work.
I realized there was a better way to separate them using cedar shingles, which are basically long, narrow wedges. By wedging a shingle between two buckets and moving it around the gap while pushing it down, I can gradually pry apart the buckets, no matter how stuck they are.
