I think some of my most interesting stories have come from chemistry classes. This is that same lab where NaOH exploded onto all are graded papers when our teacher lit the sodium on fire. I've (accidentally) lit someones lab notebook on fire. mr_utopia_man ate what he though was salt in a lab and the burning taste he got told him it was not. All the ways we got our teacher Hector off topic in high school... Good memories. :)
