Making a cloud with this palm-sized pump is easy.

Description

Making a cloud with this palm-sized pump is easy. Remove the top and put a few drops of water inside the bottle. Add air to the bottle using the pump and watch: as the pressure increases, so does the temperature. Actuate the quick-release top and due to rapid decompression, a cloud forms instantly inside the bottle! A Liquid Crystal thermometer strip measures temperature changes throughout the experiment. This hands-on activity teaches the relationship between pressure and temperature in a closed container. Approx. 26 cm (10.5") tall.

Cloud Bottle

This product arrived in perfect condition and performed as advertised. The cloud is more intense if you add a little rubbing alcohol to the bottle as the instructions suggest. A great demonstration of gas laws and cloud formation for students.

I really like it! Much better that opening cans and bottles of fizzy drink for several reasons! It was hard to get and see the cloud with cold water but when I used hot water and closed the top and left it for a while to allow the water vapour to build up inside I consistently got excellent clouds.

Great Demo!

May 2, 2019

I've been looking for a Cloud Chamber that is NOT made of class, that could safely travel with our outreach programs ... and this is it! Makes beautiful, dense clouds when used with alcohol, and the latch mechanism works very reliably with a bit of practice. Upgrade Tip: I mounted the pump on a larger, 2-liter bottle (the pump uses a standard thread), so I get much larger clouds with a bit more pumping. I also dropped in a small disk of felt (3/4") to absorb the alcohol and prevent it from being dumped out accidentally. Otherwise, the pump and latch mechanism seem durable, but the liquid crystal thermometer barely does the job --- hard to read and slow. The clouds are worth it though: I purchased two!

As a meteorologist and educator, I use the "Cloud Bottle" to help kids better understand how clouds form. Kids love clouds and the "Cloud Bottle" helps them create their very own cloud, while better understanding the science of how clouds form in the sky.

Works, but fussy and hard for a group

Mar 1, 2019

A couple of times I've gotten good clouds, but it's fussy and often doesn't make a cloud. I'd guess it would be better with alcohol. The LCD thermometer shows that the temperature goes up and down, which is a nice demo, except that its hard to share with more than one student.

Great idea but flimsy

It worked great but I broke one on the first attempt. Good thing I bought 2. I would be very careful with the cap

Problem Answers

Feb 20, 2019

I purchased 3 of these and all of them had the same problem initially. You would squeeze and squeeze and squeeze and nothing would happen. I also noticed that sometimes when you squeezed the bulb would not re-inflate and the latch seemed loose. So I unscrewed the top from the bottle and carefully inserted a screwdriver and took out the white ring, being very careful not to damage it. I then replaced the white ring and then the bottle worked wonderfully! It only took about 10 squeezes to completely fill the bottle. The cloud was great! I was using this as part of the meteorology event for Science Olympiad and the students loved it! I plan to use the bottles for the Weather and Climate Science part of a 4-H Workshop. The problem described in the questions sections seems to largely a problem of assembly. I had to reassemble all 3 of the bottles, and then they all worked perfectly.

Owner Response: Thank you, Linda for this comment. We will look more carefully at each Cloud Bottle before it leaves our warehouse. These are great little air pressure demos, and we just love them!

Students can use create a cloud with this palm-sized pump. This hands-on activity teaches the relationship between air pressure and temperature in a closed container. Very intriguing for weather lessons.
