I have made a bunch with buckets. just made a slit down each side of the bucket and then wrapped duck tape around the bucket a couple times to hold until concrete sets up. then cut tape and pull sides from each other and it will cause the bottom of the bucket to buckle a bit and the condo will pop loose. I spray grocery store brand PAM into the buckets and it works. Keeps concrete for sticking as bad and it will do a bunch of them. I think the dishpans would work better too though. Gives you a wider base, more area to sink into the mud and cause suction, wider base is harder to turn over, just makes for a bigger condo. CF
