A Short Explanation of an Unusual Possesion

Among all the random stuff in my room, gathered from seventeen years of garage sales and thrift stores, there is a jar of sand. A few months ago, I decided to start collecting sand from beaches that I visit. I found a decorative jar that my mom gave me a long time ago and put it to use. So far, there's a layer of black sand from my hourglass that I accidentally broke, a layer from California, and a layer from Florida. At the top are two paper drink umbrellas. I'm hoping to fill it completely in the next few years.
