Volcanic eruptions and rainbow lava experiment – My Little Scientist
Art and science come together in this fun and colorful experiment. This activity comes together with just 3 ingredients and no preparation; In a brown cup (close to look like a real volcano) we put roughly 1 cup of baking soda with few drops of food coloring, then we poured the vinegar, enough to start seeing the eruptions (due to acid – base reaction).
To get those colorful ripples, looking like a rainbow, we were adding the food coloring one after the other while the volcano was erupting.
We started with green, yellow and blue, first all together then one at a time to get like earth colors ripples, and ended it with the red orange to look like a real volcano!.Every time we were adding a color, Nady was pouring more vinegar to get more and more eruptions. We did many until there was no more vinegar left at home 🙂
Stunning right? Nady and I were in awe!! Don’t hesitate to try this experiment, it’s absolutely safe (The chemicals produced are non-toxic), easy and so much fun.
