Well, it’s been an…interesting weekend. While trying to be productive, I began researching the LifeStraw® because my partner and I clearly need a new debate case. Basically, the LifeStraw® is a sort of cheap purification tool that removes microorganisms responsible for causing water bourne illnesses (like diarrhea, the 2nd leading cause of death in Sub-Saharan Africa!) from [...]
