The Magnetic Wand

I spotted a small, brightly colored magnetic drawing board resting right on the lower tier of the coffee table! Tied to its side by a short string was a chubby plastic stylus with a metal tip. Naturally, I seized the wand with both blue hands to cast an epic signature rune. I dragged the tip firmly across the honeycombed screen—*skrrrch!* A trail of fuzzy dark grey lines magically bubbled to the surface beneath my stylus! Eager to see if my spell could vanish, I slid the little plastic lever across the bottom. Swish! The drawing melted completely away into blank honeycomb. Reversible magic right at my fingertips!
