How to Get Those Stubborn Slinky Kinks Out

The worst thing that happens to Slinkys is getting tangled, right?
Well, to get them untangled you need only a longish, skinny piece of metal or
other hard-to-cut material

Find the other tangle at one of the ends of the slinky.

Collapse the slinky from the first tangle to the other, then push
that chunk through the awkward loop (first tangle).

Stick the stick through as shown, then spin the slinky.

Note: hard to describe here.

If you still have a tangle on the end, then take the top-most layer and feed it below the true end.

Done!
Note: Plastic slinkys don't get that extra tangle at the end.
If you don't have that extra tangle, it doesn't matter which end you collapse
