design: Our first design failed so we made a new one that followed the guidelines. This did float but it wasn't three layers.
design: Second design but not within the parameters.
design: Third design was a hexagon and had six bars. So we printed three of them but they just sank. We came up with our next design.
design: Our fourth design failed again. There was too much weight for it to float all together.
design: Fifth design failed when printed and stacked with three of them.
