Get a reasonable amount of cold tap water. Say 450 ml (about 18 oz). Get 3 containers, each big enough to hold about 150 ml of water in them. One of these (container 3) must be suitable for holding a hot liquid in it. Container 1: Add 150 ml cold water. Stir a single dinner spoon-full (about 7 g) of sugar in. The sugar will all dissolve, creating an unsaturated solution. Container 2: Add 150 ml cold water. Slowly stir single dinner spoon-fulls (about 7 g each) of sugar in. The sugar will keep dissolving, but eventually the water will become saturated — as full of sugar in solution as it can get. Finally grains of sugar will appear at the bottom of the container. The solution is saturated. Container 3: Heat 150ml water to just short of boiling point (eg, in the microwave). Then quickly stir in lots of sugar.
