So a while ago, I was fiddling around with some clay and stuff to make microscope slides so I could view larger samples under my microscope (microbiology is another hobby of mine). Anyway, over the winter, I discovered that I could use this technique to view ants as well, and it works pretty well for me, so I decided to share it.
What you need:
Modeling clay (it doesn't have to be the pro kind; even Play-Doh would work, i guess)
1 Microscope slide (Empty, or blank, whichever refers to a slide that isn't being used for samples)
1 Cover Slip
What to do:
1. Lay out the microscope slide.
2. Take some modeling clay and make 4 "walls", each only a few mm high and as wide as the microscope slide. Arrange the "walls" in a square in the middle of the slide.
3. Place the coverslip on the clay square. There should be an empty space in the middle created by the slide, clay, and cover.
Congratz! You've made a ant microscope viewing thingy. To get the ant inside, I recommend chilling it (just to slow it down, not to kill it) and then dump it in. You may also want to chill the ant whenever you view it under the scope, because it's hard to track moving things under the microscope, especially at high magnifications. And, of course, when you're done with the ant, release it if need be. As far as I know, none of this actually harms the ant, though I think this should be done only with workers.
