Blur Experiment

Just had my first and blur biology experiment.
First time entering air-conditioned science lab... cold!!
realised that there's advantage to have lab coat now... haha!!! that's to keep warm~!~
OK!! let's talk bout my experience of using microscope for the first bio experiment.
While I want to look through the slide by using mircroscope, I see nothing... all blank and black!!!
wat happened!!?? I kept trying, but it's totally black!! why?? have a guess!!!





I didn't turn on the suis..no electric, how to function ler?!? SWT!!!
