A Levitating Sphere of Dust

A sudden sphere rose right off the floorboards! I leaped back, gasping—levitation? An antigravity field indoors? But wait! I crept closer, leaning down until my nose nearly brushed the ground. A stray seed head from a dandelion had drifted inside! With a sharp, breathless exhale, I blew directly beneath it. *Whoosh!* Up it surged, tumbling across the golden sunbeam like a microscopic parachute riding hot updrafts! Air resistance overcoming gravitational pull! Remarkable aerodynamics right at my feet!
