What should I do now? At the end of the zipper,   in the corner not covered by the tape, place some hot glue   and start spreading the powdered crayon and baking soda mixture.

Cover everything again with some hot glue. At this point, you will see that the end of your zipper has taken on the shape of a solid, sturdy square: in a word,   you will have created a new tooth   that will allow you to perfectly hold your favorite zipper garment. See how easy it is   to fix broken zippers   ? This system is infallible.

And do you know the   fork method   ? Very easy. Grab your cutlery and put the   broken zipper in his teeth. Lock the fork and run the teeth through the ends of the metal hook –   in 2 minutes you will have a new zipper   !
