Lay the slinky on a flat surface
Find both ends
Gently loosen the tightest loops first
Rotate one end slowly while holding the other end steady
Slide tangled coils apart one at a time
Work from the outside of the tangle toward the center
Avoid pulling hard on any single coil
If a loop crosses over another, lift it over gently
Keep the slinky relaxed and partially stretched
Repeat until all coils are evenly spaced
