6a cloudy snow on the ground and 40. Experimented with spritzing water droplets on the landing board or around top entrance. They went ape. The nozzle was quite close and they would dive on the droplet immediately. Kept it up for 20 minutes with no sign of slowing down. Tom Seeley said the most enthusiastic waggle dance he had ever seen was for water in winter. I have Bee Cozys on and they provide a blanket of protection for them to drink without venturing too far out. It was quite enjoyable for all of us.
