You and your children will love this hands-on, finger-moving activity. Wrap rubber bands around the one-inch starter ball, twisting and double-wrapping so they are tight. Keep wrapping until you get the ball the size you want. Then you can bounce and catch, toss, or roll the ball in whatever games you dream up—stretch your imaginations! A great activity to develop fine motor skills and hand-eye coordination. Ages 3 and up.
