The National Geographic Fire and Ice Volcano is an exciting light-up erupting volcano lab! By using just a few simple household ingredients, you can create an exciting volcanic eruption! Or fill the volcano mold with water and freeze it overnight to create an ice volcano that erupts and lights up! Create volcanic eruptions! Ice volcano eruptions light up with the built-in LED. Adventure Awaits! Experiments can be messy. Before you get started, don’t forget to prepare for excess “lava” flows in the area where you are creating your eruptions. With each experiment, keep track of the reaction when the ingredients are mixed. Which combination of ingredients works the best? Which doesn’t have a great reaction? Experiment with additional eruption formulas by adding more drops of dish soap to your recipes to see how the “lava” erupts and flows differently. All About Volcanoes!
