Surprisingly Cute & Quick
First off, i tend to rate pretty hard, so 7 is a very high rating from me. This flash needs more... voice narration, music, something. If it's meant to be educational for kids, the homoginization/bleaching process should be shown (milk doesn't go straight from a cow into a milk container).
Despite the fact that it feels like just about everything is missing from this flash, and i'm pretty sure it's going to get blammed for this reason, it's incredibly cute and short, and the flash animation is very smooth & well done. If this had a voice narration, was a little more accurate, and had some background music, i'd probably have 5/10'd it.
