1 Heading to school! Thanks for being such a great teammate, mom!
2 Quite a traveling road show! High-five mom for doing it all in one trip with me :) Ben did a good job keeping his feet on the dry ice cooler (which Mom and Richard picked up for me).
3 Getting ready - the kids are down in another classroom for computer time.
4 Making sure we have smoke!
5 Yes!
6 And they're here!
7 Adding some more water. As luck would have it, my carafe developed a mysterious leak. So I ran out of water prematurely and had to use backup systems (Ben's water).
8 Watching eagerly! Birthday boy getting a front-row seat.
9 Teaching about SUBLIMATION! (Dry ice, which is frozen carbon dioxide, goes from solid to gas - no liquid phase like water has.)
10 More science class time! Getting the caldera smoking again!
11 Candle lighting time.
12 Blowing out his candle!
13 Whew!
14 Nice class of kids. They were very excited about it all.
