Baby Soda Bottles Test Tubes & Rack

These transparent, durable test tubes are used for safe science experiments in classrooms everywhere. They can be sealed with a bottle cap, thrown in the dishwasher, dropped, tapped, or stepped on and they just won't break! Great for encouraging kids to explore and create results on their own. Each test tube measures 15 cm (5.75") tall, 2.5 cm (1") in diameter and holds approximately 50 mL (1.75 ounces) of liquid. Includes a colorful test tube rack and an activity guide with lots of fun ideas to get kids started on their new science adventure. Perfect for your Science Discovery Center. Recommended for children ages 3 and up.

What's Included?
  • 6 Large plastic test tubes (Baby Soda Bottles) with caps
    **Bottle cap color may vary.**
  • Test tube rack
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!

Customer Reviews

Always a hit Review by Denise Goodman

I wish the caps were yellow, like they used to be. But the kids love them. (Posted on 6/15/15)

Awesome! Review by F Theus

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! (Posted on 3/12/14)

Fantastic product! Review by Shannon

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! (Posted on 2/8/14)

Best Test Tubes for Kids! Review by Angela

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. (Posted on 2/10/13)

Keep Them Coming! Review by Ed

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!! (Posted on 1/13/13)

Good Buy Review by ScienceTeach

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. (Posted on 10/15/12)

Great for experiments Review by Liz b

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!" (Posted on 10/5/12)
