Grow your own soft ice tower! 🧊 Grab drinking water, rock salt, and ice - pour onto a frozen plate & watch the magic begin 🙌 ✨Behind the magic: Rock salt helps to lower the freezing point of both water and ice causing our water bottle to become super cooled! This means that the temperature of the water is below freezing but hasn’t yet become a solid. When you give this super cooled liquid somewhere to attach to, like the frozen plate, it quickly transitions into a solid! | KiwiCo
