A minor correction

(3-28-07) Well, that's what they call it in the stock market when the thrill ride pauses for a week. A correction. And in a sense we had an intentional course correction. Somewhere in the midst of all the exciting demonstrations we were so busy blowing things up that we never had time to open the Question Box. Big mistake. Because guess what is the real source for good demos? Yeah.
In that regard the Coke/Mentos demo was definitely off course. Anyway, entirely by design we had a session with no particularly dramatic demos. (I did bring in an actual I-found-it-myself-not-from-a-store fossil, from the creek behind Dittmar Rec Center). What we need here is to get back to the questions. So today's agenda was to dig out the entries languishing in the question box. Some of these were unfortunately getting pretty old. I don't want to have an Average Response Time in excess of about 13 days. Not good for the Question Box.
Questions were about cement trucks, flying cars, explosions, worldwide distribution of volcanoes, and -- hmm -- "Why does my Mommy sometimes run late".

Anyway, with less of a spectacular show, and more sit-and-talk time, the obvious risk is - - wiggliness. Yup. We got it.
But.
We also have a nice clean EMPTY question box ready for fresh stuff.
And, to my delight, one of the shyest class members came right up to me to ask about snail shells.
