Slinky (Style One)

I haven’t personally tested this myself, but it seems straightforward enough to function properly. A secondary release should probably be included as a backup. Secure one end of the slinky to a fixed point, and attach the other end to a pair of clamps. Position the keys or primary release within reach while keeping moderate tension on the slinky. Put on the clamps then lock your hands so you can’t remove them. The escape becomes harder if: you have more restrictive ties you use multiple slinkys attached to different points the keys are moved further away (requiring more stretching)
