I can actually SING to an observation (a very loud "Ah...") and see that all bees stop
(except the dancers and DVAVers)... a pretty good trick to show to people, but it is
pretty loud...
I learned about this when I was a graduate and got bored one day after 4 months of
sitting in front of an observation hive for 8 hrs a day...
try it yourself.... it even works in a real colony (with a frame out to observe).
