How to Fix a Slinky

A slinky promises hours of fun, then breaks that promise twelve seconds later when it becomes a snarl of impossible knots. You can undo these tangles with the right technique and plenty of patience, but your slinky won't always bounce back to its springy self. After enough of these incidents, it will get permanent kinks and bends, and you'll need to try more drastic measures to fix it — or buy yourself a replacement.

Untangling an Extremely Tangled Slinky

  1. Locate the least tangled end of the slinky and put four of your fingers through its center. Keep your thumb on the outside of the loop, so you can grip the end of the slinky and hold it in place. [1]
    • Extra-long slinkies might be easier to untangle if you keep the "good" part over your arm, or over a cardboard paper towel tube.
  2. Run your first finger and thumb along the slinky, approaching the first tangled area next to the end you're holding. The "good" end of the slinky will collect in a neat stack around your fingers.

  3. Slow down as you approach the tangled area and look closely, so you can see exactly where the slinky goes next. Pull the Slinky's tangled area apart if necessary to get a better view.
  4. Take the "good" slinky off your hand, and hold it so it stays in a neat stack. Turn the stack at an angle and fit it through a gap in the next tangle, so it joins the next length of slinky where your finger and thumb followed it. Once it's through, put the neat stack back on your fingers.
    • 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]
  5. If you notice a part of the slinky that's bending in completely the wrong direction, or even looks like its about to snap, try rotating the two tangled areas that are crossing each other. Once the area is under less pressure, you can safely pull apart a gap and move the neat end of the slinky through it, as described above.
  6. Continue following the slinky and collecting it on your hand. Whenever you see a tangle, use the techniques above to get through it.
  7. If you're untangling a long or extra-tangled slinky, at some point it might get too long to easily move through the gap. At this point, you can carefully set down the part you've already untangled, and switch to the other end of the slinky. Repeat the steps above until the entire slinky is untangled.

    • 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.

Getting Rid of a Small Tangle

  1. Hold both ends of the slinky, one in each hand. Pull them apart in opposite directions, just enough that you can see exactly where the tangle is. Keep holding them in that position.
    • 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.
  2. Hold the other end steady as you rotate. Rotating in one direction will make the tangled loops move farther apart; this is the direction you want. If you start rotating and the tangled loops grate tightly together, stop and reverse the direction you're rotating.
  3. Once the tangled loops have some space between them, look closely to see which loop is out of place. Lift that loop up away from the straight line of the slinky. If you keep the slinky stretched apart, the loop should snap back into the correct place as soon as you let go. If it doesn't, pick it up again and guide it carefully back between the right loops, rotating if necessary.
    • This step is easier if you ask a friend to hold one end of the slinky while you do this.

Fixing Kinks in a Slinky

PDF download Download Article
  1. This method is for slinkies that aren't tangled, but have developed bent coils or "kinks" that refuse to line up with the other coils. Some plastic slinky kinks can be molded back into place when heated, but this won't always work and could even melt your toy if you're not careful. Metal slinkies are much harder to bend back, so only try it if you have time to spare and really don't want to buy a replacement.
  2. Fill a pot with enough water to cover the slinky. Heat it on the stove alone, without the slinky in it. [3] You do not want the water to boil, but keep heating it until it becomes quite hot, perhaps just beginning to steam.
    • You could microwave a bowl of water instead, or heat water in the kettle and pour it into a pot.
  3. Turn off the heat once the water is hot. Never keep heating the water after the slinky is in it, or the slinky could melt and ruin both itself and the container it's in.
  4. Put on rubber gloves to protect your hands, and lower the slinky into the hot water. Leave it there for a couple minutes.
  5. After a couple minutes in the hot water, take the slinky out while wearing gloves. If the slinky was heated hot enough, you should be able to mold it gently into place, pressing the kinked coil down where it should go.
    • 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]
  6. If the slinky is still stiff and can't be bent, heat the water hotter and try again. Heating the slinky too much can make it a permanently ruined mess, so increase the temperature slowly and keep a close eye on the water. Never heat the slinky directly.
  7. Immediately after bending it back into place, place the coiled slinky underneath a flat book. Leave it there for several hours, or even overnight, to compress the slinky into position.
    • 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.
  8. If hot water doesn't work to repair the slinky, you could line a baking sheet with tin foil, put the kinked slinky in a stack on top of it and heat it in a 250ºF (121ºC) oven for about 10 minutes. [5] Use oven mitts to pull it out and bend it back into place, if it hasn't settled on its own. This is risky, as some plastic slinkies could melt.
  9. If all else fails, use a pair of wire cutters to cut the slinky at either end of the kink. You can try to reattach the good parts using rubber cement or super glue, but it will be difficult to attach them at the right angle. More likely, you'll end up with two permanently separated smaller slinkies.
    • The cut ends may be sharp. Try covering them with several small pieces of packing tape to protect your fingers.

      Tips

      • Metal slinkies are less likely to develop kinks than plastic ones, but almost impossible to bend back into place using home tools. They are also more expensive.

      Warnings

      • Be careful with super glue or rubber cement. Always wear gloves so that the glue doesn't stick to your hands. Keep the glue away from all parts of your body, especially the face.

      • Children should ask for adult supervision before heating a slinky or using wire cutters.

      About This Article

      Article Summary X

      To fix a tangled slinky, find the least tangled end and put your 4 fingers on the inside of the slinky while holding your thumb on the outside. Then, move your thumb and forefinger over the edge of the slinky, smoothing out any tangles you come across and stacking the rest of the slink on your hand. If the slinky is bent, spread apart the slinky so you can see where the problem is. After you've identified the issue, carefully rotate the slinky to make the tangle uncurl.
