Fizzy Ice Cube Science Fun

Summertime science fun with Fizzling Ice Cubes! Supplies: * 3 cups water * 1/4 cup baking soda * Ice cube tray * Food coloring * Distilled vinegar * Spray bottle Instructions: Place one drop of food coloring into each cavity of the ice cube tray. Mix the baking soda into the water until it is fully dissolved. Fill the ice cube tray with the baking soda mixture. Freeze for 3-4 hours or overnight. Place the ice cubes on the sidewalk and spray with the vinegar. As the baking soda reacts to the vinegar, it will begin to fizz. Kids will love to watch the bubbles and see the ice break down!
