2. Composition Fastskins are made from synthetic fabrics, which are made from petrochemicals Petrochemicals are chemicals found in petroleum and natural gases The components of petroleum (all basically composed of hydrocarbons)- Gasoline Dissolved natural gas Benzene (picture) Naphtha Kerosene Heating oils Diesel fuel Tars http://www.infoplease.com/ce6/sci/A0860338.html

3. Production Those components start out in liquid form and are put through fine holes in a spinneret. When they are out of the nozzle, they are cooled so they become solid and form threads, and are woven together to make a fabric. http://www.infoplease.com/dk/science/encyclopedia/synthetic-fabrics.html

4. Operation Fastskins improve competitive swimmer’s performances Scientists got the idea of Fastskins from sharks. The denticles on a shark’s body make it so there is a low friction as it swims. These “denticles” were put on Fastskins to reduce the friction between the swimmer and the water, and also give a gliding sensation.
