Extra-long slinkies might be easier to untangle if you keep the “good” part over your arm, or over a cardboard paper towel tube.
Sometimes, it’s easier to hold the stack in place and lift the next loop of the tangle over and around the end of the stack. [2] X Research source
it doesn’t matter which finger.
this forces the tangles to return to their normal position.
this is important, as stopping half way through isn’t the brightest.
if this method fails to work, try the other methods stated on this site.
This method is for slinkies with only a few of its loops tangled. If your slinky is too tangled to form a straight line when pulled apart, you can try this with just one small section of the slinky, or switch to the extremely tangled slinky method instead.
This step is easier if you ask a friend to hold one end of the slinky while you do this.
You could microwave a bowl of water instead, or heat water in the kettle and pour it into a pot.
If you have a cardboard tube or other cylinder that’s slightly smaller than the slinky, you can wrap the slinky coils around it to get the right position. [4] X Research source
If the book keeps falling off, try using a large, thin children’s book instead. Place a small, heavy object on the center of the children’s book, directly over the slinky. Don’t use a book that’s so heavy or so wide that it knocks the slinky over and crushes it.
The cut ends may be sharp. Try covering them with several small pieces of packing tape to protect your fingers.
