My brother decided to make such a project for a science fair many

years ago. The standard form back then was using wire mesh, some

plaster or paper mache, paint, a tin can, baking soda, and vinegar.

Of course, winning first prize with such a project isn't common as it is a

common project. It will do though, if one just wants to make a project to

be in the fair or it is a required part of the class and one will get a grade

on it.

One of my favorite sites has a couple of articles available on how to make

these standard volcanoes:

Another way to make such a project is to use mentos instead of the baking

soda and soda instead of vinegar such as diet coke. You can also make

it out of food products for a more creative effect and eat it when done if

you so choose. The recipe for this is below:

I hope that one of the articles above will suit your needs for making your

science project!
