YAYYYYYYYYYYYYYYYYYYYYYYY!!!!! I love this pair of pictures!! What FUN for the students to watch this!! To be quite honest, I would GLADLY sit in your class and be one of your wide-eyed students! Teachers have always been my best friends through my years of school, so of course I think you are amazing! :) *big hugs*

Neat! I assume the exothermic reaction is fast enough that none of the hydrogen permeates the porous ceiling tiles before ignition and makes the experiment even more exciting?

beau boom !!!*^*
