Who doesn't remember making their first home-made volcano?

Well, this is what I would describe as a semi-homemade volcano, since we used a volcano kit by Usborne, which provided a ready-made rubber/plastic volcano model.  We started by placing an empty plastic soda bottle through the top of the volcano opening, with the top sticking out.  Next we gathered the "volcanic" materials needed, and Jeromy began assembly:

1.  First, dissolve red coloring tablets in vinegar.  You can also use red food coloring.  Then pour the vinegar into soda bottle.  
2.  Squirt about 3 tablespoons of dishwashing liquid into the "volcano."
3.  Place about 1 1/2 tablespoons baking soda on tissue, wrap up tightly.
4.  Shove the tissue-wrapped baking soda into the bottle.

And in just a few moments...

A volcanic explosion!

This was really a lot of fun.  It took a bit longer for the volcano to begin erupting, we think because of the dishwashing liquid.  But once it did, it was really cool!  Jeromy had a great time with this, and can't wait to do it again.  Next time he wants to make the volcano himself out of clay, and he wants to figure out how to make the "explosion" even bigger and badder....figures!!  And of course, who am I to deny his scientific curiosity?  Having a fascination with all things rocks and mountains, including climbing and exploring them, who knows... I might just have a geologist in the making on my hands!
