Cost considerations include the materials used, the gun or process employed, consumables such as gas and electricity, labor costs, and the life of the component before it needs to be repaired.
The variable costs include the materials used to make each kite — special string for $3, the fabric for the body for $6, wooden dowels for $7, a special plastic handle for $4 — and the labor required to assemble the kite, which amounted to one and a half hours for a worker earning $20 per hour.
One particular challenge is figuring out how to embrace these advancements in technology and evolve them to include the materials required for large-scale structures.
Examples include the Materials Project at MIT [8], CatApp at Stanford [9] the Computational Results Database at Washington State University [10] and the Computational Chemistry Comparison and Benchmark Database at theNational Institute of Standards and Technology (NIST) [11].
Include the 'Materials Needed' in a list.
Remember, always supervise young children when working on projects that include the materials described above.
