      A note on sealing pollen slides.
      Nail polish leaches chemicals into the slide that mess with the grains if they are stored for long time periods. Ed Cushing at the U of MN experimented with many different sealing methods for the U of MN reference collection and he found latex paint to be the best. You can put the paint in a vial and use a tooth pick to paint along the edge of the cover slip.
      Ed's full explanation http://www.chrono.qub.ac.uk/inqua/news9/nl9-ejc.htm and an article too.

      Of course, if you are doing a quick demo and then tossing the slide, nail polish is fine.

      Nice presentation ideas, both the bees and the pollen.
