Colored ice-balls



Kristin and her kid decorated their frozen walkway with these colored ice-balls, made by filling balloons with water and food-coloring and then letting them freeze outside (it took about 10 hours).

She notes, "They're really pretty close up with cracks and fissures and brighten the front walk. I was using it as a way to introduce formulas and recipes to the kid. She was playing with food coloring in a mixing cup and I was counting drops for her. When she found a color she liked, we put that many drops in a balloon and filled it with water."
