Make Your Own Mini Volcano!
By Linda | February 13, 2008
This is another great rainy day activity.
Ingredients:
- 1 Tablespoon Baking Soda
- 1 Tablespoon Laundry Detergent
- ¾ Cup Water
- ¼ Cup Vinegar
- Food Coloring (red is good to simulate lava)
Directions:
1. Combine baking soda, detergent, water and food coloring in a jar
2. Place jar on a tray or cookie sheet
3. Pour the vinegar into the jar and watch the “eruption”.
What causes this?
A chemical reaction between the baking soda and vinegar releases gas which forms the foamy bubbles which overflows from the container.
