Incredible Science Fun Learning Ideas:

  • Explore the wonders of science while doing th experiments from the included instructions inside the included giant test tube. Each Super Tube instruction sheet contains directions for at least three distinct science activities around the theme of the Super Tube.

In addition, the Super Tube itself has an interesting background and offers even more scientific activities.

Scientists use test tubes of all different sizes and shapes to study and collect really cool things. A test tube can hold a liquid like water. A test tube can be used to collect samples of many different small items.

What makes this test tube so great? Most test tubes are made of glass. This test tube looks like it's made of glass but it's really plastic. It is hard to break if you drop it but there's something else special about this test tube. What are those grooves on the top? It kind of looks like the top of a bottle...a plastic, 2-liter soda bottle to be exact.

The Test Tube looks like a Baby Soda Bottle. It's modeled after the plastic forms that are sent to the bottling company and blown up through a molding process into a 2 liter soda bottle. Very hot air is blown into the test tube and this makes the plastic stretch like a balloon and fills the inside of the mold. It grows about 40 times its original size!

Think of other things you can do with the Baby Soda Bottle.
