  3. Understanding; the materials I used. Wooden skewers: Wood is made from trees, it is a natural biodegradable material. Blue tack: Blue tack is an adhesive material; which contains hydrocarbon polymers. Polymers are extremely sticky; they are long chained hydrocarbons; which have lots of hydrogen on the surface, which tend to form physical bonds with anything they come into contact with. Blue tack also contains mineral filler and hydrocarbon oil, which combined, limit the stickiness of blue tack. These additional properties allow blue tack to stick, yet also be peeled off and re-used. (How blue tack works, 2003)French Onion Dip container: The container is made from plastic. Plastic can be defined as; any material which can be shaped or moulded into any form. Plastics are made from oil and do not react chemically with most other substances.Plastic does not decay therefore; recycling plastic or reusing it for another purpose is the best way to dispose of the material and prevent further pollution. (HowStuffWorks, 2013) Paper: Paper is made from plant fibres and from trees; wood is processed into chips, water is added to turn the chips into a mush like pulp and then the pulp is sprayed onto screens to let the water drain and the fibres bond. Paper is thin and flat, to ensure that paper is uniformly thin, the pulp is sent through a series of rollers. It is sustainable; used paper is easily recycled into new paper. Paper can be recycled; between up to 5 or 7 times. (Recyclebank, 2013)
