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!

<p>This website is very good for science experiments and for school students to follow, check out and get great grades for their research!</p><p>thank you</p><p>chloe pace</p>
<p>Thank you so much for this! I needed it for school... it was so much easier to do the project with this! </p>
<p>Ilike you</p>
<p>In my Case it is for school</p>
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!<br>=D<br>Much better results!
<p>an where/what is the source of them?</p>
<p>This experiment was awsome, I LOVE IT</p>
<p>it is a very good step to show how is volcanic eruption is caused </p>
<p>nice now i know how to make a volcano</p>
<strong>NICE INFORMATION</strong>
<p>Thank you so much it helped me a lot in the last minute</p>
<p>Does it work?</p>
<p>Sorry about the first one I deleted it by accident </p>
<p>do you mean <strong>spelt incorrectly</strong>? Radioactive? </p>
