Wow!

We have an observation hive.  This afternoon they finished off a round of syrup in the boardman feeder.  I replenished the syrup and within a minute many workers began to Nasanov in the direction of the feeder.  A minute more and a half dozen workers began to round dance.  It was remarkable!  Often when I am talking to kids I scramble for BIG IMPACT demonstrations to catch their attention.  I am thinking that a demonstration, where a description of Nasnov pheromone and round dancing is given, and then a feeder is put into place, and the kids witness the dramatic change in behavior would leave a lasting impression.  Now, I just have to repeat it on cue.  I guess the trick will be to have many bees ready and waiting for feed to have them react so dramatically.  Anybody try this on a regular basis before?
