We just took out our spice grinding. This is a new activity and the kids are having a blast with it. We are grinding nutmegs and the smell is divine. The kids like the smell as long as they don't take TOO big of a sniff! (: I've already had to go back to the store to get more nutmegs. We are going to try cloves and cinnamon this week. I hope they work. The kids love experimenting so they will love to see if this works.
