Marshmallow catapult & more

Looking for something to keep the kids busy while they are out of school? Here is one more thing to try (and it looks like loads of fun), compliments of the Kitchen Pantry Scientist. All you need for this experiment are some rubber bands, the plastic ring from the neck of a prescription bottle or the ring from the lid of a plastic milk jug, and a bag of marshmallows.  You’ll also need a chair turned upside down to complete your catapult.
