Yesterday, was the day of the trick or treat and the costume parade, but what is more fun for a science teacher than to introduce some real halloween magic by showing lots of chemical reactions and spooky and cool science demonstrations.
If you burn boric acid with pure alcohol or methanol, it burns green, sodium chloride (salt) burns yellow, and lithium chloride burns red.
Nothing says halloween like dry ice, frozen Co2
We did several exothermic experiments, which caused crazy foam to shoot out of a test tube or a large mushroom cloud from a chemical reaction, burning magnesium which burns a bright white flame , changing wine into water (using acids and bases and universal indicator solution) and of course dawning our costumes.
