Giant Test Tubes (Baby Soda Bottles), 6 pack

These clear, unbreakable baby soda bottles (also called giant test tubes) are great for kids! Use these "baby" soda bottles to mix, shake, show reactions, grow things in, or use as observation chambers. They function as a giant test tube, beaker, or storage bottle. The large threaded caps are easy for smaller hands to put on or take off – the bottle can also be tipped upside down, so the cap becomes a base.

Put your Giant Test Tubes to work right away using the included activity guide. Learn about the density of different liquids, how to make a homemade battery, slime, crystals and more, including science fair ideas.

These can be used with our 5-hole plastic test tube rack.

Why are they called baby soda bottles?

These test tubes are actually the blanks or preforms used to make soda and water bottles. The preforms are typically injection-molded from the raw plastic pellets at a plastic products manufacturer and then shipped to large soda and water bottling plants. The bottling plant uses a blow molding machine to heat the preform and "blow" it into the shape of the finished bottle using compressed air. The finished bottle is then leak tested, filled with soda or water and capped. Shipping preforms instead of the finished soda bottles significantly reduces shipping expenses for the bottling plant. Our "baby soda bottle test tubes" are the kind of preforms used to make 1- to 2-liter soda and water bottles. They are made from polyethylene terephthalate (PET), a safe plastic used for beverage containers. The caps are specially designed to contain the pressure buildup common to carbonated soda drinks.
