Объяснение:

Добавляем в смесь теплую воду. Помешивая раствор сахар раствориться в воде, опилки процедить через фильтр или иными подручными средствами, допустим через сито. В воде растворенный сахар, чтобы выделить в чистом виде растворенный в воде сахар, нужно упарить раствор, оставив немного воды, а затем охладить его – в результате в осадок выпадут кристаллы сахара
