Stay tuned for the continuation of our story, When Will They Ever Learn, after a word from our sponsor:

MiraFount Horse Waterer - never haul water again!

And now.... 

the rest of the story:

I'm thinking that the horses are supposed to learn to push the blue "hamster bottle ball" down with their muzzles to get a drink from the tank. Just as Pippin was trying to do in the video. But, you see Doc snip at Pippin, saying,  "You idiot, that's not the way to do it" as he rudely pushes Pippin aside Doc neither listens to, nor responds to the human's comment. He shakes his head in disgust at Pippin's poor attempt at getting a drink and then shows Pippin how it should be done.

This, dear friends, is how you are supposed to use the waterer:

I believe the premise behind the blue balls is to keep the water clean.  Uh...having Doc plant his size 2's in the fountain doesn't exactly lead to clean water!! I guess we will have open topped waterers in the near future.
