Use your skills to move your yard and household waste to a composting station without sending it into storm drains.
Marbles represent leaves, grass clippings, or hazardous wastes.
As you look down through the table top you will see the marbles gather in the lake or river below. You'll learn why storm sewers should carry only rain water and snow melt. This exhibit is a great challenge for teams of kids and adults. Requirements Marbles tend to disappear over time and will need to be replenished.
