The Department of Biological Sciences at the University of Alberta brings you this flash animated video tutorial specifically relevant to your student laboratory courses, specifically microbiology. If you're a student at any school of biology, this information will be helpful for learning how to make a wet mount.
The trick to doing a proper wet mount is to start from one side and force any air out the other so no bubbles are trapped. This animation will walk you through the procedure, showing the coverslip, the sample, water, and the glass slide. Now all that you need is a microscope.
