How Do You Make A Model Volcano?

You will need NaHCO₃ (baking soda) and CH₃COOH (vinegar) for volcano to erupt.

Ingredients:

• White vinegar.


• Newspaper.


• Empty 2-liter bottle.


• Salt dough or plaster.


• Red food coloring.


• Baking soda.


• Plywood sheet.


• Brushes.


• Spray or acrylic paints.


• Liquid dish soap.


• Clear sealant.

Now follow the following steps:

1. Have a sheet of plywood to make a base. Therefore, it should be at least 8 inches wider and longer than your deigned volcano.

2. Place an empty 2-liter bottle at the middle of the plywood and place a salt dough or plaster to make a mountain around it. Make sure to leave the top uncover.

3. Place the lid or open top tightly around the opening of the bottle.

4. Make edges and paths starting from the volcano's top and till end (at the base) so the lava flow through these paths.

5. Now let the model volcano dry, after that coat it with acrylics or spray paint.

6. Combine one tbsp. Liquid dish washing soap, baking soda and a few drops of red food color in a mug.

7. Put the mixture in the bottle.

8. Place the volcano outside.

9. Now put 1/4 c. White vinegar in the mixture present in the bottle and stand back to see the volcanic erupt!
