Step 1: Build
Slip the hooks in to the wing nut and screw the wing nut into the machine bolt. Make a dent at the end of the bolt in the middle.
I drilled my dent though you tapping a nail into it should work.
Step 2: Remove earrings
Now simply continue to screw the bolt clockwise while holding the wing nut steady and you will efectively be pulling back the loops off of the earring without placing any stress on the earlobes. You will find that even the most stubborn earring will come off effortlessly.
