We are going to start right at the beginning – before plastic there was monomers. A monomer is a molecule that can join with other molecules to form a chain of molecules. A chain of monomers (or molecules) is called a polymer. So, a polymer is a chain of monomers or molecules. Chains of polymers [...]
Did you know that aluminium drinks cans have a plastic lining. It’s there to stop acids in the beverage from corroding the metal which is not good for the can or the flavor of the contents. If you don’t believe me, you can try this experiment, as done by Steve Spangler, to separate the two. [...]

Ethane and propane are “cracked” into ethylene and propylene which are combined with additives, mixed up [...]

Today, the plastics they discovered—polypropylene and polyethylene—are used to produce the vast majority of the thousands of plastics products all over the [...]
Oil is sold between countries in quantities called barrels. (The same measurement is used to sell whisky.) One barrel of oil is the same as: 159 litres (about 80 large fizzy drink bottle) 35 gallons (enough to fit in the petrol tanks of about 4 cars) 280 pints (a lot of bottles of milk) The [...]
