[nabs-l] Volcanoes

[Carrie Gilmer]

Dear Tony,
The ones I have seen you can buy at specialty toy stores or science museum
toy/souvenir stores. I suppose you could google it or science museum and a
state for example. I know Maryland, Minnesota, and Texas all have good ones,
many do these days. So does the Smithsonian. I have made my own. You can use
play doh or modeling clay and build a "mountain" leaving a hole in the
middle with a place for a cup at the bottom and a straw or plastic tube. In
all the kits it is vinegar and baking soda that makes the "volcanic"
eruption. You could add some red food coloring I suppose to make it look
like hot lava. I have not tried that and don't know what it would do to the
chemical balance, don't think much.

It works great and is fun. I have done it at Saturday School, and it is fun.

Hi I am taking a geology class and this is tony Sohl. I am wondering are
there any tactile models of volcanoes? I am looking for tactile models of an
eruption of one. If anyone knows where I can find one then let me know.
