Getting clean drinking water might be something we take for granted for those of us living in developed countries, but countless others around the globe see it as a luxury. Anyways, if you are not sure about the kind of water that you’re about to down when outdoors (or in a dodgy area), why not consider the $10 Water Bobble? It is patented filtered water bottle that comes with its own filter, ending up looking like a baby bottle. All you need to do is fill it up and let the filter do all the hard work. No idea if this will kill bacteria or not though.
