ANOTHER GAME TO PLAY WITH THE HERD- Ball Toss. Would also make a great "rainy day" activity. You could even find tubs or buckets of varying sizes (like nesting bins) for more of a challenge for the older kids (Think Skee-ball).
DIY: Bubble recipe and refill station. Love the idea of reusing plastic cups from restaurants as the containers. Keep the bubble solution confined to one big refill container, and no worries about leaky, yucky containers hiding all over the house!
