Soda Bottle Preforms and Caps (30/pk)

Description

All plastic soda or “pop” bottles start as a small plastic tube called a
preform. When this preform is heated and blown into a bottle shape, it is
ready to be filled with your favorite carbonated beverage. Our preforms come
with full-sized final threaded openings so they use standard plastic soda
bottle tops (included). Use them for a problem-solving activity by seeing if
your students can guess their use. All bottle caps may be used again and
again. These preforms are air and water tight when covered tightly with a
bottle top and so are perfect for collecting or storing liquid samples.
Preforms are ~11 cm long x 2.5 cm in diameter (~4.3″ x 1″). Interior volume of
preform is approximately 25 cc (~0.84 fluid oz). The polymer in our baby soda
bottle preforms is polyethylene terephthalate, commonly known as PET. This
polymer has a monomer formula mass of C10H8O4, a melting point of 260o C, and
a specific heat of 1.0 kJ/(kg-K). It has a glass temperature of 70o to 80o C,
when it starts to soften. Package contains 30 Preforms and 30 bottle caps.
Bottle caps sold separately as well. Cap color may vary. Note: Our new
preforms are slightly shorter than prior models but they will still fit in
your Preform Rack (TT-100) – and they’re still perfect for Super! Wow! Neat!
experiments.
