Instructions

Mentos Soda Volcano

1

Open a bottle of clear-colored soda.
2

Place a few droplets of red food coloring into the bottle. Continue applying food coloring until the soda turns a deep red.
3

Recap the soda bottle and cover your work area with newspaper. Place the soda bottle on top of the newspaper.
4

Cover the soda bottle with mounds of newspaper and construction paper, leaving the top of the bottle exposed to resemble a volcano.
5

Insert a Mentos candy and back away to view the eruption.

Classic Volcano

1

Fill a personal soda or juice bottle with a few spoonfuls of baking soda. Crush several antacid tablets and place them inside the soda bottle as well. Insert the base of the bottle into a cardboard tube.
2

Craft a paper mache mound around the tubes, leaving the tip of the bottle exposed.
3

Paint the mound brown and gray, to resemble a volcano.
4

Add a drop or two of red food coloring to the vinegar.
5

Pour a splash of vinegar into the volcano top opening and watch the eruption.

Coordinating Model

1

Craft a model of the composition of a volcano to accompany either actively erupting volcano models.
2

Glue two shoe boxes together to form an "L" shape.
3

Leave the insides of the "L" shape bare but craft a paper mache mountain mound on the top, sides and back of the boxes. Paint brown and/or gray.
4

Pile cotton on top of the volcano peak and secure it in place with glue. Add a label that says "ash clouds."
5

Paint the inside of the "L" shape of the shoe boxes to resemble the different levels of a volcano's composition. These would include the red main magma chamber, which forms a funnel shape, narrower at the top peak of the volcano and wider toward the base, a line that marks the earth's crust, a secondary vent and the main vent, or volcano opening. Label the different areas of the volcano.
