There are probably many ways to make a volcano. I recently experimented with two different kinds. The first one we made was the traditional baking soda, lava red food coloring and vinegar. The second volcano we made was with diet Coke and Mentos candy. Here’s our video of our two experiments, scroll down to read the do’s and don’ts if you’re going to try this at home:
So with the baking soda and vinegar, put some vinegar in the bottom, then add the baking soda, then add more vinegar. The effect is much bigger than just pouring it on top of baking soda. Also, shake up the red food coloring and vinegar before you bury the bottle.
And with the Diet Coke and Mentos, bury the bottle of Diet Coke with the lid on. Just before you’re about to launch the volcano – take off the cap and throw in the mentos. I think if you did this at night, with flash lights on it, it would be really cool.
Enjoy!
