Maximum stretch
Ah, this is a hard one too… I am cuffed to a radiator in the hallway and the key is around the corner, well out of reach. Fortunately for me I am cuffed to a stretchy workout thing, so there might be a little hope of an escape. This thing is very hard to stretch, which is probably good for exercising, but not good for me… I need to keep a lot of tension on this thing to get to the key, and even then I can only hope to reach the key with my mouth, not with my hands…
