This is my black and green marble drop. I chose black and green because they go good together and I happen to like the color green. I took a risk with the design and steepness of my drop. It is successful because whenever you put the marble in, it drops and ends up in my clay bowl. It starrts at the top, drops at a rapid pace, falls into my push pin pit and the marble bounces and bounces until it rolls into my clay bowl. This IS my favorite project, but it took some time and effort to make.
