Once it firms up, you are going to have to trim the excess off the tops (around the edges) Then take a SS putty knife and literally cut out each bar. Meaning go around each side of each bar with the dividers still in place. Once you do that, you SHOULD be able to get the Rectangular part of the mold off. Then just slide something flat under each bar and take them off the slab. Once you get enough of them off, you MAY be able to take out some if not all of the dividers. And then.......................... DON'T EVER DO THIS AGAIN! ETA: Nice swirlies!!!
