The Leaping Disc

I nudged a dropped round wooden magnet across the floorboards. Scritch-slide! It glided smoothly toward the refrigerator. Just as my round belly pushed it near the bottom edge, snap-clack! The disc suddenly leaped right off the floor and slapped flat against the steel door! I tumbled backward onto my feet in pure astonishment. Leaning in again, I gave the wood rim a tentative tap with my horn. It held fast. With a sturdy heave of my tummy, I pushed it sideways, watching it glide across the brushed metal without falling. Metal has its own invisible grip!
