Big Brother got a volcano kit for his birthday.   Apparently it is not painted in random colours... red = lava, black = obsidian, brown = dirt, grey = rocks, (mostly metamorphic, apparently), and blue = rivers.  But you knew that, right?


  1. I have always wondered what baking soda and vinegar teaches about volcanoes?
    I have also always wondered how to get my husband to do laundry.

  2. 1) nothing at all... but it does teach about acid/base reactions and the coolness that is the release of carbon dioxide.
    2) can't help there, just got lucky.
