What does it teach?After performing this "signature" demo for 30 years, Don Herbert discovered a problem with the rationale for doing the experiment in the first place. Now, you can help your children wonder and discover the real lesson behind the demonstration.

Great Science Expirement Project

We purchased the Expanding Baby Bottle to use for our sons Soda Can Pop Science project. This product offered him a great visual to use at the science fair that was teacher approved. They really didn't like the idea of shaking cans of soda and tapping them on the side and than opening them. Using the baby bottle allowed him to demonstrate his experiment with a great visual. It was a hit. He had a crowd by him all day.

This is a cute demonstration that I use to open my science demonstration program. I tell the kids this was my 1st "test tube".
