I give this activity a B-. Ideal would be that we had a backyard and the weather was nice. We don't. It wasn't. He played for about 30 minutes inside the pan and then went to pouring it out and onto the kitchen floor. Luckily it swept up easy. I threw the sweepings away rather than saving it for play agian because of the lint and hair that was now mixed in with it. TIP: sweep your floors before indoor play so that you can sweep up any spilt sand and reuse it in the container.
