Kid Project- Make your own butter

I LOVE doing this with the kids!  Pour some heavy whipping cream into a small sealable tupperware container OR ziploc bag...let the kids shake to their hearts content (and maybe then some) until you notice a ball forming inside...then shake some more!  (consider it the exercise that we will need to work off the BUTTER we're gonna eat! LOL) The ball will be the butter and all the clearish liquid around it is the whey.  Pour off the whey and spread that real "homemade" butter on some little crackers!  YUM!!!
