We have been looking at the uses of plastics and synthetic fibres.
Carbon Fibre helped team GB win 12 medals in the velodrom. It is used in the manufacture of cylcing helmets, brakes and chain rings. Javelins, racing cars, golf clubs and yacht masts can also be made from carbon fibre.

Teflon
Speedo won the battle of Beijing with more than 90% of the swimmers donning its LZR costume, cotated in water resistant Teflon. Teflon is also used in the manufacture of GoreTex and non-stick frying pans!
Silicon, Latex and Lycra are used to make swimming caps and cycling shorts.
Moving on to the winter olympics

The most popular plastic in the world is used in manufacturing snowboards and skis.
It is also used to make bulletproof vests, knee and hip replacements, milk bottles and shopping bags - WOW!
