The kids loved this idea...We decided to be smart and use the marshmallows that I have in the cabinet left over from Xmas and some old Halloween Peeps. The boys were so excited...what boy wouldn't be excited about playing with a candle of course with proper supervision. We discussed all the different aspects of how a flame works, why does the marshmallow burn faster when it's closer to the flame, we talked about how the marshmallow changes when it's heated up. I could go on but I don't want to bore you with all the details...you get my point.
I came to the conclusion that you don't need money to have fun and it sucks having to tell a friend "no" becuase you don't have the money. I'm really working hard on fighting the urge not to run to the store everytime I want something for the kids. Plus, being my kids teacher is very rewarding and fun!
