In this week's spotlight: a pair of science projects perfect for burning off some energy and getting your "spin" on. What is the secret to a good hula hoop? Experiment with the weight and size of different homemade hoops to see how each affects your ability to keep a hoop in motion. What's the best combination? Can you hula hoop longer with a lighter or heavier hoop? Why?
