Hello, I work at a public Science Museum, and we are building an observation hive for patrons to view the bees and see how a live hive works. However we have heard from one of the people who is helping us build the hive that we need a special kind of tint on the glass so that it doesn't confuse the bees, and they are able to escape properly to the outside world. I've called a couple of automotive tinting shops and they weren't sure what kind of tinting should be use, as most of the tinting they use it has to be lighter on the inside of the hive than the outside of the hive. I'm curious what is typically used for this purpose to help the bees be happy and survive through the winter. Any help would be most appreciated.
