What's this Snow I hear?

Have You Ever Wondered What the Snow was made of in all of those early classic films?

Well here's the answer.

Classic Cinema first started out using painted white Corn Flakes. 

Then when It's a Wonderful Life was made, due to the loud noise the flakes made, Frank Capra used foamite with soap and water. The effect... Classic. Which also won an award for the new technology. Pretty cool, huh?
