Because you wanted to spend the next half hour doing something awesome. I’m really impressed with the organization of groups and periods on this!

Researchers looking into cutting down on the use of poisonous chemicals in military arms (flares on armor-piercing bullets specifically) have developed a few alternatives. Sodium and potassium periodate act quite similarly to the perchlorates without the negative side effects. They can also be applied to civilian fireworks which, considering they’re essentially flaming chemical baskets that rain down into rivers and lakes as well as seeping into the ground, is a great step toward cleaner celebrations.

Greener wars, greener fireworks
