Pool noodles seem to overly abundant, and cheap, this time of year. We decided to pick up a couple at the local dollar store and create marble chutes. We cut them in half using a steak knife. The cutting was very easy to do, and barely made a mess. We then used a tv tray, some painters tape, and a bucket to catch the marbles at the bottom.
As the project became more elaborate we incorporated toilet paper rolls and match box cars.
