Ten things that cannot dissolve in water include: oil, plastic, sand, glass, metal, rubber, ceramics, wood, wax, and flour. These substances are either hydrophobic (repel water) or have molecular structures that water cannot break down, making them insoluble. Knowing which materials do not dissolve in water is crucial for applications like waste management, construction, and separating mixtures in daily life.
