Interesting. I wonder if I can convince the author to set up a slightly different experiment: put an ordinary stone pebble in place of the shungite; or place a shungite to the right, and an ordinary pebble to the left and see which one the bees prefer...It seems like bees as a species are not thriving as they were as a whole, particular ones of the urban variety, due to a number of environmental stressors on them, be it lack of food, air quality, and prevalence of greater number of cell towers that may prove to be cytotoxic. A man conducted a test, placing beehives near a 5g tower, and as it comes to no surprise to many, much of them died off within a season.
There's another guy using shungite to protect bees, and says that it helped to protect them and keep their numbers high.
Now, unless the guy is putting honey on these lil nugs of shungite, the bees appear to like being close to them:
Very strange properties, it reminds me of the Q-Link pendant with SRT technology that appears to lighten the mental load one feels from everyday stressors. Not sure how it works exactly, but it looks like it is having some effect on bees at least.
Because it might be that the bees are just curious about the foreign object sitting at their front porch. Worth trying IMO!
