This week, we investigated different substances in science – salt, sand, rice, oil, honey, washing-up liquid and oobleck (cornflour and water) – and we discovered that not all materials follow the simple rules of solid, liquid and gas. Salt, sand and rice are solids which can be poured like liquids, but they pile up into a heap unlike liquids! Oobleck can be poured like a liquid, but if you hit it or move it quickly, it crumbles like a solid – very mysterious!
