You know those moments when you think of something so awesome but also so obvious and wonder “how did I not think of this before?” I had one of those last week – retroreflective nail polish!
Retroreflective means that a material reflects light directly back at its source. For night time cyclists, this means that the light from a car’s headlights is reflected back at the driver, making you look far brighter and more visible from a longer distance. Retroreflective materials are used in things like street signs and markings, high visibility safety wear, and to improve visibility of trailers & train cars.
Last year, I procured some traffic grade retroreflective glass spheres (spheres so small they’re almost a powder). I used them to turn bracelets and silk flowers high-vis in Retroreflective Goodness and to make the magnets in Bike Art Galore. The technique is easy: pour the glass powder over wet paint, let it dry & shake off the excess so there’s a single layer of glass spheres on the surface.
To apply to nails, simply embed the spheres in the final coat of wet nail polish! I did a blue stripe over a purple base coat and then just gently laid my nail down in the powder.
Hand signals just got way more awesome! Like with paint, the lighter the colour, the brighter it will be, and metallic colours look amazing.
So far, the retroreflective nails have worn better than just the regular polish, leaving me with another problem: how to remove it. I usually rub polish off with an acetone soaked rag but I don’t dare rub the retroreflective glass. Remember the Mohs hardness scale – glass scratches fingernail. I figure I’m going to have to invest in the type of nail polish remover where you dip the whole finger in if I’m going to have any chance of getting it off without damaging my nails. Another issue I’m having is keeping it clean. If I do up my whole left hand I’ll have to start wearing a glove (which I’m not a fan of) while I’m wrenching to prevent any bike grease from taking up permanent residence. At least one thing that I was worried about, the glass spheres detaching and getting into everything, hasn’t happened though.
