The mixture was so hot that the chemical components in the baking soda started to separate. This is called thermal decomposition. The baking soda broke down into different parts: water, sodium carbonate and carbon dioxide. The bubbles inside the finished candy are created by the carbon dioxide being released into the mixture. It cools so fast that the bubbles donʼt have time to pop, and the gas gets trapped inside the candy.
