How Does It Work?

Why are these test tubes called Baby Soda Bottles? Steve Spangler coined this name when he introduced them to teachers everywhere as the world's greatest test tube for kids. Believe it or not, Baby Soda Bottles are really just that: baby bottles before they are blown up into the 2-liter soda bottles you see in the store. Here’s how it works: 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. When the plastic cools into the shape of the mold, the bottle is ready to fill with your favorite refreshing drink.

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!

  1. Always a hit review by Denise Goodman on 6/15/2015

    I wish the caps were yellow, like they used to be. But the kids love them.

  2. Awesome! review by F Theus on 3/12/2014

    Purchased these for my daughter's science project. They work perfectly and I'm happy to announce that she is now growing Basil in these test tubes in desert sand!!! These make a perfect greenhouse! Great buy!

  3. Fantastic product! review by Shannon on 2/8/2014

    We used these for our annual Family Science Night for the Salt Water Density straw demo. They are hight quality, durable, and have a million other uses. (And the caps don't leak, so they can be pre-filled and transported without worry!) They will be used again and again by our PTA for Science Night, but would hold up great in the classroom as well. The rack is a great addition and also durable and easy to assemble and disassemble for storage. Highly recommended!

  4. AWESOME!!! review by kathryn houghton on 4/10/2013

    These are awesome for experiments and such. You get what you pay for!

  5. Best Test Tubes for Kids! review by Angela on 2/10/2013

    Not only did I use these for my son's science theme birthday party, I also use them at my child care centers. These are the best test tubes for use with children. I love that you can close them up and they do not break. They are also a perfect size for a variety of uses.

  6. Keep Them Coming! review by Ed on 1/13/2013

    We love to use the “wow items” for discrepant events in our Harris Super Science Saturday (HSSS) programs. Our students of poverty are severely lacking in background experiences that new learning needs to be connected to. Fascinating material can get their attention, motivate them and fill in some of the gaps they have because of their lack of experiences.

    Magic sand, lava lamps in the baby soda bottle test tubes, and melting blocks are some of the things we use and just this past week I attended 2 of our nighttime HSSS Meet and Greets and saw again the reaction of students and their families to investigating these fascinating materials.

    So keep them coming, Steve Spangler Science!!

  7. Other use too review by Gary on 12/5/2012

    I used these to hold scroll saw great!

  8. Good Buy review by ScienceTeach on 10/15/2012

    I teach middle school kids and they love using these baby soda bottle test tubes simply because they are baby soda bottles. These test tubes work well for all the chemistry labs we do and I couldn't be happier with them.

  9. Great for experiments review by Liz b on 10/5/2012

    My students love to mix colors in them, do density experiments, and grow water jelly crystals. Its a great value, they are sturdy, and the kids love to take them home. They are my "go to!"

  10. Perfect review by brie on 8/30/2012

    I used these as a decoration at my sons birthday party. We filled them with different things and let the kids play with them. At the end of the party I put some of the colored Orbs in them as party gifts for ther guest. Everyone loved it!
