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.

- Expanding Baby Bottle Review by Jim B.
This works very well, and is a Great experiment.(Posted on 5/9/13)
However, the nipples pop, and there is No way to buy replacement "no hole" nipples without buying the whole kit.
Steve Spangler Science needs to offer replacement "no hole" nipples without buying the whole $10 kit.
I have made this suggestion by email and finally got a weak response two weeks later. Also, I spoke by phone with a Steve Spangler representative that said she would pass the suggestion along.
I truly feel like I am being ignored on this issue. PLEASE offer replacement nipples without holes, Or let me know where I can buy them.
Please don't feel like your requests are falling on deaf ears. We take our customer requests seriously, and when we say we will pass your feedback and suggestions along, we do so. As far as offering replacement blind nipples, we don't have any current plans to make them available for retail, and aside from our source, we have no leads as to finding these nipples elsewhere. Feel free to give our customer service team a call at (800)223-9080 if you have any other questions. Thank you for your feedback, Jim, and keep experimenting!

- Great Science Expirement Project Review by J Urbanski
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. (Posted on 4/30/13)
