This magnetic snake can be useful in many ways, domestic or industrial. You can tie too tightly and then easily untie when demagnetized. You can use it magnetically active or inactive, and can choose a number of options of sizes and intensity of desirable magnetic force.
You can change her shell to adapt the material for specific uses. It can be waterproof and be made with cheap materials (great materials like neodmio and other common materials in the DIY environment).
My foot model is the foot snake.
The name of my design is Snake Leg
