A broad family of specially constructed memory plastic bands, they can act as ties, clamps, connectors and other similar tools.
Most coils are 1 cm. wide and packaged in flat, concentric loops. They act as cheap throwaway substitutes for heavy-duty pulleys, straps and mechanical saws. All have a maximum expansion (see table below) and contract to 1/100th of their length.
Memory coils can cut down trees, pull jail cell bars together, hoist vehicles, crack walnuts, open cans, hold gear to the hull of a vehicle, act as an emergency tourniquet and much more.
The contraction is usually triggered by a chemical agent or a pre-specified electrical current. The tightening effect takes 1 min x meter of length. Any coil can be used only once, and must then be cut away (Sonic Knifes are good for it, requiring no more than 1 round to do so) or dissolved by a specially designed catalyst (cost: 10 Cr./dose).
