Honey on Tap

This is incredible, extracting honey without even opening the hive:

How do the Flow™ frames work?
The Flow frame consists of already partly formed honeycomb cells. The bees complete the comb with their wax, fill the cells with honey and cap the cells as usual. When you turn the tool, a bit like a tap, the cells split vertically inside the comb forming channels allowing the honey to flow down to a sealed trough at the base of the frame and out of the hive while the bees are practically undisturbed on the comb surface.
