I had my husband try to release this from the mold after I loosened the edges with a knife. He said the Dalek broke in half and was unrecognizable as a Dalek because the details stayed in the mould.
Here’s what the portion of the mold that Dalek came from looked like after I got any of the Jello out
Here’s what the remaining Dalek looked like while it was still in the mold
The Daleks got stuck in the mold and wouldn’t release. This is the result of my trying to gently heat one side enough to remove the Dalek.
