The pop is an easy source of sugar for the bees so when they find it they will take all they can. It is junk food for them also though.
I don't know what honey just from pop would taste like, because a colony of bees can have as many as 80,000 bees in all harvesting from about a 9 square mile area. So it would be hard to tell.
It probably would make a difference though, because the flavor of the honey changes as the different types of flowers bloom.
An interesting note, I heard that somewhere in Missouri there are flowers that bloom that when the bees make honey from it it can make humans hallucinate but has no effect on the bees. The beekeepers make sure not harvest honey when those flowers are in bloom.
This is probably a stupid/unanswerable question, but I was just pondering the fact that I see bees fly into pop cans all the time, and I wonder if they actually "drink" the soda and make honey with it. Then I was thinking, if that was possible, then surely some scientist somewhere might have been curious enough to create some sort of bee enclosure filled exclusively with pop cans instead of flowers and tested whether the bees made honey and whether that honey tastes delicious (because honey made with one type of flower always tastes different than others) or is mindbogglingly unhealthy. I don't know, maybe not... Has anyone else ever thought about these weird experiments that they'd do if they were a scientist or is it just me?
