Description
A fun and educational science experiment to create a bubbling ‘salt volcano’ using common household ingredients.
Ingredients
Scale
- 1 cup room temperature water
- 1/4 cup vegetable oil
- Salt (table salt or rock salt)
- 1 clear glass jar or cup
- Food coloring (optional)
Instructions
- Fill your clear glass jar or cup about 3/4 full with room temperature water.
- Gently pour vegetable oil into the jar until there’s about 1/2 inch floating on top. Let it settle.
- Add a few drops of food coloring to the oil layer for a colorful display (optional).
- Slowly sprinkle salt into the jar. Watch it carry oil downward and create bubbling eruptions as it sinks and dissolves.
- Keep adding salt to see ongoing bubbling. Observe the interaction between salt, oil, and water.
Notes
- Ensure the jar is stable to prevent spills.
- This experiment can be repeated with different colors of food coloring for varied effects.
- Consider performing the experiment over a tray to catch any spills.
