Baby Food

I just got home from dropping off Christian at preschool. I came home and cleaned up the kitchen and tossed a baby food jar away. Then I got to thinking...I could probably use it for something. I was searching on the internet and came across this! What do you think? I think it could make a really cool advent calendar especially if you put something cool on the lids and then a small suprise inside!
