A Magnetic Discovery

I waddled over from the pantry straight toward the giant white refrigerator! Right at the very bottom edge, almost touching the floor, stuck a small rubber magnet shaped like a bright green pickle. I reached out both hands, gripped its bumpy sides, and gave a sharp tug! Plop! It released with a soft snap, but when I touched it back against the metal panel, it jumped right out of my palms and stuck itself back on! My mouth fell wide open. I pried it loose again, slid it up and down the enamel with a smooth whispery squeak, and tested every corner of the metal door. It's like the fridge has invisible sticky hands!
