We realized that the diameter of the most commonly used straw is the same size as honeycomb cells, which means the straw has the perfect size for the most important bee species for pollination to be born: the apis mellifera. In order to build Last Straw beehives, we collected straws in rivers and fields, sterilized them, and created a design using 100% recyclable materials. In our design, the aesthetic responds to the functionality. It was inspired by Langstroth Jumbo traditional hives, created to produce honey but also ideal to increase bee population. Usually, bees build their hives starting with a perimeter. With Last Straw, the perimeter is already done, so they work less and reproduce more quickly. In the end, we achieved our two principal goals: increase bee population and reduce plastic pollution. The Last Straw blueprints are available under a Creative Commons license, so anyone can make use of this idea.
