PPLD Kids built incredible towers, bridges, and mazes! We designed our own marble mazes with paper plates. Next, using only 20 binder clips, 20 paper clips and 30 tongue depressors, we tested our mettle building the tallest tower and the strongest bridge. Our tallest tower was 13 inches and our strongest bridge held 16 books! This is definitely something you’ll want to try at home. Do you think you can beat Palmer Lake Library’s record?
