A glider for the ground

Fly? Dinosaurs don't fly—what if the wind flipped me right into a hedge? But you mentioned flying, and looking up at the high brick walls, I got curious. I scuttled from the garden path into the covered breezeway where a discarded folded cardboard takeout sleeve lay flat on the smooth concrete. My knees gave a nervous twitch, but I dragged over two dry sycamore leaves with my claws. Bracing my heels, I wedged the sturdy leaf stems under the cardboard folds to form wide swept-back wings. I hopped on top, tested my weight, and slid three inches across the slick floor! It glides without leaving the safety of the floor.
