When I was in college, there used to be tiny yellow dots on parked vehicles and in other places as well. I saw the same thing at District Center in Janak Puri. It took me some time to realise that one thing both places have on common are a lot of beehives. I don't know how the bees carry the pollen or the nectar but what I do know is that they drop some of it and that is what we see as yellow dots.
Does anyone see a potential market for leak proof/spill proof pollen carriers for bees. “PollenCarry Ultra—Double your production without increasing the effort. Think of all you can do in the extra time!!”
