Picture this: you’re casually holding a black “Sharpie” pen between your fingers. Nothing to see here, folks! But wait, flip it around and—ta-da!—it’s a red “Sharpie”. Take a moment to bask in the astonishment (your audience will need it). Show those empty hands again, flip the pen, and voilà, back to red. Fancy a change? The pen can swap colours as many times as you fancy. No dodgy paddle moves here, just pure visual magic that’ll leave everyone scratching their heads.
