First of all, my father and father in law are chemical engineers that have taught chemistry in the public schools. I know they would get a kick out of that experiment and go jump on doing it themselves right now because they still find that stuff fun.
Next, where I teach, we have the kids come up and tell us about their "special holiday". No matter what it is. They come dressed in their traditional clothing, and tell us about why they celebrate things like Chanuka, E, Ramadan, Kwanzaa, Christmas (which is not Christianity - but Santa), Diwali, Easter...etc. We even have one child who doesn't celebrate anything (including birthdays) and we learned why. The kids learn to respect, tolerate and accept one another, differences and all. I think school is a perfect setting to teach this.
