Science Experiment Lab Report

Question: Science Help, Please! 10 points will be rewarded to the person that helps the most!?
I need some help getting background information for my lab report for science. I need some information about what makes something a colloid (like butter, for example). I would really appreciate any help with this. Thanks in advance!!!
Okay, so I just finished doing an experiment, which was to make butter. I put a marble inside of a container, and filled it with heavy cream. I kept shaking it for 10 minutes, and there was a lump of “butter” inside the jar, with a liquid surrounding it. Then I let it sit for 10 minutes, and it was mostly just a lump of butter without a lot of liquid. What kind of mixture is that liquid??? And if you can, please help answer this question, too : What do you think was happening at the point when a change was happening in the container???
I REALLY APPRECIATE ANY HELP!!! PLEASE AND THANKS!!!
REMEMBER: 10 POINTS TO THE 1ST BEST ANSWER!!!
