new, and hopefully failproof (fingers crossed) experiment

which brand of nail polish last the longest

rough idea but the basis is i buy different brands of nail poils of the same colour (or try to). i paint a square of each brand on a plastic strip of some sort. i'll sure nail polish remover to get it right. then i soak the strip with the nail polish blobs in vinegar (?). they'll be in plastic containers and this way i can do the whole thing all at the one time. to measure out the amount thats been worn away, ill place the plastic strips on grid paper and estimate to the best of my abilitys.

LEST HOPE THIS'LL BE ALRIGHT DX
