Our pals at Popular Science explain how they made salt in an experiment, for popcorn. The video is rad – Theodore Gray writes – “Sodium is a soft, silvery metal that explodes violently on contact with water and burns skin by reacting with even the slightest moisture. Chlorine is a choking yellow gas, used with mixed success in the trenches of World War I (it was known to have killed about equal numbers on both sides of the trench). When these chemicals meet, they react in a fierce ball of spitting fire and clouds of white smoke. The smoke is sodium chloride (NaCl), or table salt, which I used to season a basket of popcorn I hung over the reaction.” – Link.
