Cornflour is made of lots of long,stringy particles.they don't dissolve in water but they do spread themselves out.this allows the gloop to act both like a solid and a liquid.when you roll the gloop to act like solid and liquid.when you roll the mixture in your hands or apply pressure to it the particles join together and the mixture feel solid.but if it is left to rest or it is held up and allowed to dribble the particles slide over chea other.
