Coaster Launchpad

I spotted a tall ceramic mug standing right on a wooden coffee table! Charging across the varnished surface, I leaped straight toward a stacked cork coaster at its base. My feet caught the edge, wobbled, and suddenly the top coaster slid forward like a mini surfboard! I rode the slick glide for three inches before bumping gently against a stray metal spoon. Total victory, even without web-shooters!
