Building a volcano for a science project is a fun procedure that can be accomplished in about 30 minutes. To make your own science project volcano, you need flour, a container, salt, warm water, cooking oil, vinegar, food coloring, detergent, a plastic bottle, a pan and baking soda.
Mix flour, salt, cooking oil and water
Using a container, mix 6 cups of flour, 2 cups of salt, 2 cups of warm water and 4 tablespoons of cooking oil. This should create a substance that has a doughy texture and consistency.
Mold the mixture into a cone
Place the soda bottle in your pan. Use the mixture you just created to make a cone shape around the outside of the bottle. Make sure the hole remains unsealed during this process.
Fill the bottle
Pour some of the water and food coloring into the bottle until it's almost completely full. Then, add in 6 drops of detergent and 2 tablespoons of baking soda. This helps the liquid inside the bottle develop an explosive, erupting reaction.
Pour in some vinegar
Wait until you are ready for the eruption, and then dump some of the vinegar into the bottle. The liquid inside the volcano should now erupt outwards.
