Tools and Materials:
Mini bungee cords (10 inch)
Not pictured: Super glue
Snip the ends off the bungees, and give them all a good couple of stretches. (This way, they will slide easier over your wrist.)
Thread all the bungees through the copper coupling.
To connect the ends of each bungees: Hold the two ends in one hand. Use the lighter to melt down the nylon around the rubber core. Working quickly and carefully, press the two melted ends together to fuse them together. (You're fusing the colored threads around the rubber core. )Repeat for each bungee.
Slide the copper coupling over the fused ends, and use a toothpick to add ample glue inside the coupling, securing the bungees in place.
