I've had the containers for a while intending to use them as terrariums. As you can see that hasn't happened yet, so I thought they'd make for a fun bowling game. O and I are not so good at bowling. We threw beanbags at the bottles and rolled a ball at them. As you can see from the pictures, O's aim is way off when she threw the beanbags. Unfortunately, my aim was not much better when I rolled the ball at the bottles (or maybe I'll blame it on our uneven floor!).
