This project used 1,581 recycled soda bottles to create a canopy for shading from the sun. The project incorporated 3D modeling and scripting software to generate the desired surface created by the bottom of the soda bottles. The project sought to stimulate creative alternatives for recycling and reusing materials.
Each bottle is filled with a small amount of colored water. The specific color of the water is based on the elevation of the bottle relative to the groundplane. Each bottle is hung from a grid by a unique string length ranging from 6" to 30".

Step 1: Digital Fabrication
I used Rhinoceros, a 3D modeling program to create the surface that the bottom of the bottles form. From this form, we used Grasshopper (a scripting program) to generate a dataset containing the length of each string corresponding to a coordinate grid system. For simplicity, we label one direction of the coordinate using numbers, and the second direction using letters. The dataset, in addition to providing the location of the string, provided the color of liquid in each bottle that would hang from each string.
Step 2: Cutting String
For this step, over 20 people volunteered their time throughout about 3 weeks working to prepare each individual string to hang each bottle. Each string was labeled and cut to a specific length per the length denoted by the table. A washer was tied to one end of the string so a bottle cap with a hole drilled in it could be hung from the string. This step takes many hours and is rather tedious. Each individual was given 51 string lengths to cut in one sitting (the number of bottles in one column of the structure). Doing it with other people makes this step in the process much more enjoyable.
