How Do You Make Lava For A Shield Volcano Model?
A shield volcano, such as those that formed Hawaii, is built from lava flows. These create a broad and gently sloping dome shape. The violent eruption when vinegar and baking soda mix together is a good representation of a cone volcano, not a shield volcano. Create a slow-moving, gooey substance for the lava in a shield volcano model. Mix 1 1/3 cups of warm water with the Borax in the measuring cup. Stir with a wooden spoon. Mix in 6 drops of red food coloring. Set aside. Mix 1 1/2 cups of warm water with the 2 cups of glue in a mixing bowl. Use the wooden spoon to stir. Pour the solution from Step 1 into the bowl with the glue mixture. Gently lift and turn the mixture repeatedly. Not all of the water will be absorbed by the new substance. Continue turning until approximately 2 tablespoons of water are left unabsorbed. Lift the final result up and allow the excess water to drip off. The substance will be sticky for a moment. Place in plastic bag for storage.
