Glass is made of sand, soda and lime, or to be more precise, silicon dioxide, sodium oxide and calcium oxide. Sugar is made up of crystals just like sand. When the sugar is heated, the sugar molecules break apart. The molecules reconnect as the sugar syrup cools forming a clear solid. Silicon dioxide, the main ingredient in sand, is one of the most abundant resources on earth.
