How do you make a salt dough volcanoe?

Answer 1

The Exploding Volcano

This may get messy!

Ingredients:

• Salt dough:

- 6 Cups Flour
- 2 Cups Salt
- 4 TBSP Oil
- 2 Cups Water

• Plastic soda bottle (2 litre works best)
• Baking sheet
• Warm water
• Red food colouring
• 6 Drops Liquid dish detergent
• 2 TBSP Baking soda
• Vinegar

Instructions:

1. Create a "salt dough" by mixing ingredients in a large bowl. Mix with your hands until the dough is smooth and firm. Add a little bit more water to the mixture if needed.

2. Stand the clean soda bottle in the middle of the baking sheet. Mold the salt dough around the bottle, making sure that you don't cover up the bottle mouth (the hole at the top) or drop any dough into the bottle. Take your time and build the volcano of your dreams…

3. Fill the bottle most of the way with warm water mixed with a little of the red food colouring.

4. Add liquid dish detergent into the bottle.

5. Add baking soda to the water/detergent mixture in the bottle.

6. Slowly pour vinegar into the bottle and jump back!

Notice the red "lava" that flows out of your volcano. This happens because of the baking soda and vinegar mixture. By mixing the two together you produce a chemical reaction in which carbon dioxide gas is created - the same gas that bubbles in a real volcano! The gas bubbles build up in the bottle, forcing the liquid "lava" mixture out of the bottle and down the sides of your volcano.

Answer 2

Real Working Volcano!

6 cups flour
2 cups salt
4 tablespoons cooking oil
warm water
plastic soda bottle
dishwashing detergent
food coloring
vinegar
baking dish or other pan
2 T baking soda

Directions
First make the 'cone' of the volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).

Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Don't cover the hole or drop dough into it!

Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you don't take so long that the water gets cold).

Add 6 drops of detergent to the bottle contents.

Add 2 tablespoons baking soda to the liquid.

Slowly pour vinegar into the bottle. Watch out - eruption time!
