If you want color you can add food coloring into the balloon before filling. The next step is industry standard water balloon filling. Wrap the balloon around the faucets and fill with water. Careful so you don’t break the balloons. Set them outside for freezing. The time to freeze depends on how cold it is where you live. We unwrapped the balloons when they were only half frozen, made a hole and poured out the water that was inside. Voila, you have an ice sculpture; put a tea candle inside.
