Hi, I'm not an engineer. I'm writing a script and one of our characters is an electric engineer. In one scene, she is kidnapped and must burn through ropes using available items in the middle of nowhere.
I've researched foam cutters enough to know that you need 3 things: a power source, conducting wires, and the "blade" (usually a piece of steel wire). I've tried duplicating this at home using a D battery, two silver conducting wires (because a silver necklace is feasible here), and a steel wire blade. It sort of works, but it's very slow to heat up, and I'm also trying to figure out how you can hold this thing without burning your hand. Can anyone suggest a way to improve this design? I need a reasonably quick way to burn/melt rope.
If there were a 12V or a car battery around, would that work better, or is it too much power/too dangerous? I'm happy to clarify any details. Thank you.
