Cloud in a Bottle
Learn the science behind forming clouds, weather, and more with this kit
Usually ships out the next day.
Recommend for 8 years & up with adult supervision.
Deal of the Day
This kit may not control the weather, but it might just be the next best thing. This mind blowing experiment will show how pressure and water vapor in the air compress and expand in a small scale version of what happens in the atmosphere. You'll make your own clouds and learn all about the science behind their formation with this great new hands-on kit. Recommended for children ages 8 and up.
What's included?
- Clear plastic bottle
- Foot pump
- Rubber stopper
- Safety glasses
- Activity Guide
How does it work?
Cloud in a Bottle works by creating factors inside the bottle that are necessary for the formation of clouds. Pumping air into the bottle introduces high pressure, and releasing the air allows the cloud to form. This kit is a simple, hands-on version of what happens in the atmosphere every day.
What does it teach?
Cloud in a bottle teaches the basic principles behind cloud formation and how it relates to high and low pressure.

Cloud in a bottle is great experiment
DeLoss - January 29, 2012
My son is a weather fan and wanted to do something weather related for his 4th grade science project. The cloud in a bottle worked perfectly. Scientific, meteorological, and a little pop at the end to keep the kids interested! |

Pilots Having Fun
Sue - January 17, 2012
The local chapter of the Experimental Aviation Association decided to hold a week-long aviation summer camp for teens, and I volunteered to teach some weather. I used the Cloud in a Bottle Kit, with a touch of isopropyl alcohol in the bottle provided, to demonstrate Bernoulli's Principal. Summer is too hot and humid here, to try the experiment with hot water. This was a fun project and everyone got a chance to participate. I used a cap left over from a soda bottle to capture the cloud, and say a few words about density and fog. The kids named the cloud George, before it was turned loose - by lowering the air pressure. |

Wonderful!

I love this! I have had this for over two years. It is a hit with preschoolers all the way up to adults. Everyone loves the POP! when you release the pressure. The cloud is very visible and dramatic. This experiment very nicely shows the phase shift of water to water vapor with changing pressure. Think PVT (pressure, volume, temperature) diagram. On their own nchildren often come up with the idea of changing the liquid type as a experiment. They are intrigued to find that a milk, apple juice and grape juice clouds are white too. After seeing this they can often deduce that the water is the only thing that is vaporizing and that the molecules that give the liquid color are to "heavy" to be vaporized into a cloud. It is just a short step to then talk about salt water oceans and fresh water clouds. |

Cloud Burst in a Bottle
Roger Davis - August 2, 2011
Very happy with this demonstration. Simple yet very "eye" catching. The underrated part is the "pop" that happens when you release the stopper after pumping up the bottle. Also, rubbing alcohol works better than water in making clouds form. I used this for elementary aged kids and they loved it. A little hard for them to use the pump, but otherwise its great. They seemed to really be more intrigued with the dissappearing cloud when pressurized again. Thanks Steve. |

Pump Broke
Tristan - March 29, 2011
It works great, other than the fact that the air pump broke within a day and I had to fix it. |

AWESOME! dont try and do it yourself this kit is worth it!
Amanda Parnell - March 24, 2011
I tried to make my own before I purchased this kit and it just ended up taking up a lot of my time. The stopper for the bottle is key and the pump itself is worth $20! I love Steve Spangler Science and plan on ordering more of his great products!! |

I really love this product. I used it with my kids at home and at school and everyone really loved it!! The students even wanted the name of the website so that they could find products too. |

This is such an amazing way to teach about weather. It brings it down to a scale that everyone can understand. I even understand the world a little better because of this! |

Wahoo! It really works!
Jenny Brown - September 10, 2010
Once we got the hang of holding the stopper in place tightly, it worked beautifully. We also found that rubbing alcohol worked WAY better than water. Too cool! The glow in the dark paper we used in this video is also AMAZING! We use it all the time in Children's Church. It really gets their attention. |

Awesome!!! Everything that I have bought from you guys (except for the Singing Rod that not even the instrument teacher can get to sing) has been a classroom and neighborhood pleaser. |
