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 C10
, a melting point of 260o
C, and a specific heat of 1.0 kJ/(kg-K). It has a glass temperature of 70o
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.
Note: Heavy/Dense item. Higher shipping rates may apply, especially for express orders, and orders to Alaska and Hawaii

Owner Response:We apologize for the size change. We were not able to get the original sizes any longer. We listed the new size on our website and in our catalog, but we will try to make it even more obvious, especially for our customers who have purchased in the past. The good news is that they still fit in the preform rack and though they are a little shorter than they used to be, they are also a little wider, so the overall capacity didn't change dramatically.

Owner Response:Thank you very much for the heads-up. We have added an extra check for the caps on the preforms. We appreciate the feedback.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s)
Students can use Mixing Wells in an investigation to describe and classify different kinds of materials by their observable properties.
Students can use Mixing Wells to make observations and measurements to identify materials based on their properties.
Soda Bottle Preforms can be used to develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Students can make observations of the Mixing Wells to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
Students can use the Mixing Wells in an investigation to analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Students can experiment with the Mixing Wells to evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Soda Bottle Preforms can be filled with water and a piece of aquatic plant, and placed in the direct sunlight. Students can construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
Soda Bottle Preforms can be filled with water and a piece of aquatic plant, and placed in the direct sunlight. Students can use this to illustrate how photosynthesis transforms light energy into stored chemical energy.
Soda Bottle Preforms can be used to investigate, construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
Soda Bottle Preforms are clear, sturdy and have a firm seal conducive to a number of classroom activities or storage of samples.
