So this is a thing, and since it was on sale at the local beauty supplies shop, I caved and bought a bottle and one of the little magnets the other day.
After playing with that one bottle, I went back and bought it in every single color they had while it was on sale. ****, ladies, this is the coolest thing that you can apply to your nails. And I sound like a cyborg, too, when I describe how I got the effect on my nails.
Now all I think about is how badass a car would look covered in this stuff.
On the other hand, I'm sort of disappointed that I didn't get super powers from it. If they marketed nail polish to guys, they'd need to have a disclaimer: "This product does not turn you into Magneto. You will not have the power to single-handedly destroy electronics at will. Sorry."
