How do hand sanitizers work? Let’s see what sanitizer normally contains. The first and most important ingredient is alcohol to help tear off that fatty coating any bacteria have. When a germ gets in contact with alcohol, its coat bursts off and it can no longer cause you any harm since it’s not active anymore.

But if water were not available, could hand sanitizers be a good alternative? How about looking to the hypothetical future of the planet Earth? So, the world’s not that different – most things that were so common in the 21st century still exist in the 22nd. Turns out there’s only one major change, and it’s water supply.
