How to Make a Baking Soda Volcano With Papier Mache

by Lanh Ma, Demand Media

    A volcano model made out of papier mache is a craft project that allows young children to get messy while learning about chemical reactions. Build the volcano out of papier mache and then add to the fun by causing the volcano to "erupt" using vinegar and baking soda. This simple project takes several days to complete, but each stage allows the kids to participate.

    Step 1

    Cut the top 4 inches off of a bottle of water using a pair of scissors.

    Step 2

    Center the plastic water bottle in the middle of a shallow cardboard box, open end up.

    Step 3

    Secure the plastic bottle to the box with several lengths of masking tape. Apply the tape in an L-shape between the bottle and the cardboard.

    Step 4

    Crumple several sheets of newspaper into balls.

    Step 5

    Cluster the balls around the plastic bottle.

    Step 6

    Secure the newspaper balls by wrapping masking tape around them. You are creating the shape of the volcano, so don't worry if it looks lumpy and irregular.

    Step 7

    Cut a sheet of newspaper into strips that are 2 inches wide.

    Step 8

    Mix 1 cup of water with 1 cup of glue in a large bowl.

    Step 9

    Dip the strips of newspaper into the glue and apply them to the side of the volcano shape. The papier mache gives the volcano a smooth shape. Continue until the mountain is completely covered.

    Step 10

    Allow the papier mache volcano to dry for at least 24 hours.

    Step 11

    Paint the volcano with acrylic paint.

    Step 12

    Allow the paint to dry completely.

    Step 13

    Fill the water bottle at the center of the volcano a quarter of the way to the top with baking soda.

    Step 14

    Pour vinegar into the volcano from above and watch as the volcano immediately erupts.
