Had our kid-posse over today (which is 4 third graders + 1 first grader + 1 kindergartner) and among other things (many other things) we painted and adorned the paper-mache volcano Eleanor and I started LAST summer (and had not finished yet). Then we tried a variety of concoctions the internet promised would simulate a volcanic eruption. We've tried the mentos + soda mix (lack luster at best, maybe the type of soda really does matter?) and several baking soda + vinegar mixes (meh). We even dumped baking soda into the regular soda, for a pretty good reaction. Nothing was that impressive, and I'd like one of you to explain the chemistry going on here so I can design a more dramatic eruption. Speak up!
Short clip of our eruption here.
