How To Make An Erupting Volcano Model

Making A Working Volcano Model

When I was in school I had a science project to make a exploding volcano model. What I came up with worked and was pretty cool to me as a sixth grader. I took a mason jar and used it as my base. Next I took a paper mache mix and worked it up along the jar to make it volcano shaped making the mache work into the mason jar edge. You want to make a lip on the edge so that when the volcano erupts and pours out it does not go on the floor. The next step was to color the mache making it look like a real volcano, you could use marker or model paint, and even put clay or play dough around it to give it more depth. Now you take and mix equal parts of baking soda and vinegar, when you combine them in the jar you can add some food coloring to give it the lava look, it will spill over the edge and flow down. This should make a nice erupting volcan model and the more effort one puts in the better result and grade you will get. I hope this makes a fun project.

hi..this was really useful for my science project. im just wondering, ahmm, will the volcano really erupt when i add baking soda and vinegar to it?? or should i just test it here at home first before the final science fair??

TOGIA 7 years ago from OHIO Author

I would put the baking soda in the cavity of the volcano - then add the vinegar. It will start to foam and work its way up and over the sides of the volcano. I have heard of people using food coloring to make the actuall foam look more like lava. Just use your creativity and have fun.

This trick is awesome or else you can try with pouring a mentos(mint) in a cold-drink the same reaction will take place. Another trick is if we add some salt in coldrink then also it will do the same reaction...


WARNING:be careful it can blast your home too...
