Baby Soda Bottles are large, clear, and plastic. Unlike ordinary glass test tubes, these thick-walled plastic tubes can be thrown in the dishwasher, dropped, tapped, or stepped on and they just won't break! Baby Soda Bottles are really “baby” soda bottles … they’re actually 2-liter bottles as they appear before being blown up into big bottles. The tube is placed into a vacuum mold and heated. Then, very hot air is blown into it, stretching the plastic like a balloon so it fills the inside of the mold. The tube grows to about 40 times its original size. When the plastic cools, the mold is opened and the bottle falls out ready to be filled with a delightfully refreshing liquid.
Over the years, Steve Spangler popularized the name Baby Soda Bottle (BSB) for this test tube looking container… and now you know why. These clear, durable test tubes are used for safe science experiments in classrooms everywhere.
