We have come up with a Skating Saucer! It has a round, rubber surface and wheels. You can jump on it, bounce on it, roll around on it, and fun-bump other saucers. It’s sort of like a combination round skateboard and small “bumper car” that you might find at amusement parks. And it can be used indoors or outdoors. Plus, it has brakes and an “undercover” so that the wheels stay still if you want to spin around in the snow!
