Salt Volcano
An engaging DIY project that combines art and science by creating a volcano that erupts with colorful lava using common household materials.
Ingredients
Volcano Structure
- 1 cup salt
- 1 cup flour
- water water Add gradually to form dough
Eruption Materials
- 1/2 cup baking soda Place in the crater
- 1 cup vinegar Pour into the crater for eruption
- optional: food coloring For coloring the lava
- optional: container for baking soda Use if you prefer to hold the baking soda separately
Instructions
Create the Volcano Structure
- In a mixing bowl, combine 1 cup of flour, 1 cup of salt, and add water gradually.
- Mix until you’ve formed a dough-like consistency.
- Shape this dough into a volcano structure on a baking dish or tray, leaving a small crater at the top.
Prepare for Eruption
- If desired, use food coloring to dye the dough for a colorful volcano.
- In a small container (if using), place 1/2 cup of baking soda in the crater of the volcano.
Erupt the Volcano
- Slowly pour 1 cup of vinegar into the crater.
- Watch eagerly as the mixture fizzes and erupts like lava!
Experience and Enjoy
- Observe the colors and the reaction as it mimics a real volcanic eruption.
- Take notes on the sensory experiences—smell, sight, and sound—as it erupts.
Notes
Customize the shape and color of the volcano. You can also add glitter for extra visual appeal and create mini volcanoes with smaller amounts of materials.
