"MOM!!" he shouted at one point. "You've gotta check this out."
"Wow. What is it honey?"
"My booger. I never knew it would look like this."
"Umm... yeah. Neat." Glad to know he's so inquisitive, but yucko. (I made HIM wash the slide and slip cover!)
On another note, I like this microscope as a beginner's microscope because they can look down through the top or look at the image from the front (see the photo below). I don't know if this is common, but I like this feature.
