Answer: Cotton wool fibres

What you're looking at

Cotton wool is the soft, fluffy material you find in first aid kits, cosmetics bags, and medicine cabinets around the world. It's a staple in homes everywhere, used for removing makeup, applying medicines, and gentle cleaning. Most people handle it regularly without thinking twice about its structure.

When magnified this much, cotton wool transforms into an alien landscape of twisted, tangled strands. The individual fibres reveal their true nature as delicate threads with a slightly rough texture, bundled together in a chaotic web. It's hard to recognise because we normally see it as a smooth, compressed pad rather than this intricate network of separate filaments.

Look for tangled, thread-like strands with a soft, slightly textured appearance when examining fibrous everyday materials.
