Snow Volcano - kids science experiment - baking soda and vinegar

Snow Volcano ? ages 3 ? This snow volcano was so easy to make and entertained the boys for hours! Start by making a big pile of snow, then put a small plastic bowl in the top. Fill the bowl with vinegar, a little dish soap and some food coloring or liquid watercolors. Finally add a heaping tablespoon of baking soda mix and watch the lava flow. Keep adding vinegar mixed with food coloring to keep it going. We also kept adding more baking soda when it started to stop bubbling. So fun! =======================
