Introduction: How to Make a Model Volcano Erupt

Picture of How to Make a Model Volcano Erupt

Model volcanoes are a staple of student science fairs. They can also be a lot of fun for a summer family project. Making a model volcano erupt is a simple process. This article will tell you how to make a model volcano erupt.

Difficulty: Easy


Things You'll Need:

  • 1/2 cup water
  • 1/4 cup vinegar
  • 1/4 cup dish detergent
  • Red or orange food coloring
  • 2 tablespoons baking soda
  • Tissue
  1. Build your volcano. In the center, use a container to hold liquid. Depending on how big you are making your volcano, this can be an old water bottle, soda bottle with the top cut off, or even a simple glass jar.

  2. Add ingredients to your container. This includes water, vinegar, dish detergent and food coloring. Do not add your baking soda at this stage.

  3. Add the baking soda when you are ready for an eruption. Wrap the baking soda in a tissue and drop into the volcano. The baking soda will react with the vinegar and cause the eruption.

  4. When constructing your volcano, you could get very clever with release mechanisms for the baking soda. A hidden trip lever could be built in which is tripped with a fishing line. Attach the baking soda here, and pull the string instead of dropping the baking soda in the top! This is a way to surprise people at the fair!

I think that you need to rethink your plan to make this experiment. I tryed to make it your way but it didn't work so well

dogloverr (author)2016-09-13

this is going to be great for class

Instead of Vinegar (5% Acetic acid, a weak monoprotic acid) and Baking Soda (Sodium Bicarbonate, a weak base)you should really use Hydrochloric acid and Sodium Hydroxide!
Much better results!

Where could you possibly find these in ingredients?

Jessica Hall (author)TheHawkeye2015-10-21

In my Case it is for school

rodniactive (author)2010-11-28

your code name is uncorrectly
the correct spell for that is toxic

TylerW2 (author)rodniactive2015-02-14

you spelled incorrectly incorrectly!

SmartboyB (author)2014-12-14

This experiment was awsome, I LOVE IT

priyanshu.soni.3367 (author)2014-12-10

it is a very good step to show how is volcanic eruption is caused
