This father-and-son team from Australia found their passion in beekeeping, but they dreaded the hassle of extracting honey from a beehive. It required costly equipment that sometimes hurt or disturbed the bees. So the Andersons created Flow Hive to put honey on tap. Their simple idea not only is saving bees globally, but also has become the largest Indiegogo campaign of all time by raising $13.2 million. They are now shipping worldwide. See the campaign.
