I'm always a fan of activities that can be turned in to a game of some type. This activity does that in a wonderful way. I had a lot of fun experimenting with different smells from what I had around the house. Which sounds a little strange, but I actually had a blast having my wife quess what each smell was. While it would definitely be the most fun around Halloween, this activity can be done at any time and it's fun to try all different shapes and "creatures".
