haha, me and my buddies used to try that challenge. Although our rules stated that you had one hour and it had to be 1% or thicker. Everyone thought it would be real easy, but I only saw one person out of about 30 make it. A few people thought it would be easier to do, with chocolate milk that was always funny.

It's supposedly because of the lactose, right?

Wouldn't that make skim milk actually harder?

Try it out!

I have been drinking a gallon of milk every day for the last 5 months, I could not drink it all in a half hour that would make me sick. Do this everyday and you will gain a lot of weight I guarantee it. Whole milk!
