How does it work?

Why are they also called Baby Soda Bottles? Over the years, the name Baby Soda Bottle (BSB) for this test tube looking container because its home is actually in the bottling industry. At the bottling plant, the tubes are placed into a vacuum mold and heated so they soften. Hot air is then blown into the tube, stretching the warmed plastic to 40 times its original size to become a 2-liter soda bottle. When the plastic cools into the shape of the mold, the bottle is ready to fill with your favorite refreshing drink. So, you can see why it’s referred to as a Baby Soda Bottle.

What does it teach?

Baby Soda Bottles can be used to teach kids more things than you can imagine! Grow plants, observe critters, collect water samples, explore different densities, hydrate polymer crystals, and mix all the colors you can find in a rainbow. Kids are only limited by their own creativity—put one of these test tubes in their hands and they’ll be sure to discover something new!
