Hedef

Yenilebilir bir ürünle aşırı doygunluk ve çekirdeklenmeyi göstermek için bir iplik üzerinde büyük sakkaroz kristalleri büyüterek akide şekeri elde etmek.

Arka Plan

Rock candy is made by suspending a string in a supersaturated sugar solution and waiting for crystals to grow. Sugar is unusual in that it is extremely soluble in water (about 2 kg per liter at 100°C) and forms large monoclinic crystals with well-defined facets.

Güvenlik Uyarıları

  • Sugar syrup is extremely hot — burns risk
  • Supervise children during the boiling step
