How To: Build and make an erupting volcano model at home

Hmm... wondering what to do with a lazy Sunday afternoon? Why not build a volcano that can erupt? Have fun and make a mess, all in the name of science!

You Will Need:
• 6 c. flour
• 2 c. salt
• 1 c. water
• Small plastic bottle
• Baking sheet
• Acrylic paint
• Paint brushes
• 1/2 c. vinegar
• 1 tsp. red food coloring
• Dishwashing detergent
• Tissue
• 3-4 tbsp. baking soda
• Cardboard (optional)
• Glue (optional)
• Toy trees (optional)

Step 1: Make clay
Make homemade clay by mixing the flour and salt in a bowl, and then adding water until the mixture is smooth in consistency.

Step 2: Center bottle
Center the bottle on the baking sheet.

Step 3: Shape volcano
Shape the clay around the bottle to make it look like a volcano. Start at the bottom, creating a wide base, and work toward the top. Make sure to leave the mouth open.

Step 4: Paint the volcano
Paint the volcano with the acrylic paint to make it look more realistic.

Step 5: Add liquids
Pour the vinegar, red food coloring, and a few drops of dishwashing detergent into the bottle.

Step 6: Add baking soda
Fold the baking soda into a tissue and drop it into the bottle, and watch in wonder as your volcano erupts.

Trivia: When Mount St. Helens erupted in 1980, the eruption caused the mountain's elevation to drop 1,314 feet.
