The practical usefulness of chemistry is often overlooked. In the video game State of Decay, there are various monologues that characters can randomly give. One such monologue speaks about how one person is amazed that all of the toilet paper disappeared after the zombie apocalypse. He jokes that while everyone else was worried about food and ammunition, someone realized that they’re going to continue to use the bathroom, so they’d better stock up on two-ply. In many ways, this represents the two modes of thought on preparedness. You have the people whose first thought is rightfully their immediate needs. You need food, water, shelter, and safety. And then you have the people who think beyond these needs. Both are equally important. Surviving today means little if you’re going to die tomorrow. However, tomorrow means nothing if you can’t survive today. Basic knowledge alone can help a person in both. Chemistry is often overlooked, but can provide vital supplies to us, both immediate and what might be viewed as luxury. Let’s examine two ways that chemistry can help us in these matters.
Grid Down, Bug Out Scenario
Let’s look at our first scenario. The grid has gone down and we have decided to bug out.
A Method to Make Safe, Purified Water
While we have a method to boil water, this doesn’t mean that it’s purified and perfectly safe to drink. Rivers and streams contain some degree of industrial or agricultural runoff. Let’s assume that we somehow forgot, lost, or broke our filtration method. Can we make a method of filtration with only what’s in our vehicle? If we assume that we have one common household item and a suitable container, we can.
