The Science Behind Smoke
The smoky Chemists
Description :
The Smoky Chemists really impressed us with their experiments!
With a series of impressive chemical reactions, rapid sublimation of dry ice, and rapid cooling of a banana and roses using liquid nitrogen, they created a video that left us amazed. All of this resulted in the production of thick smoke and steam, which is why they’re called the Smoky Chemists!
Of course, experiments like these require caution, we always remember to wear gloves and safety goggles, whether we’re in a lab or elsewhere!
Congrats to the Smoky Chemists for everything they showed us!
The smoky Chemists
The Smoky Chemists conduct a series of demonstrations designed to reveal how materials respond to rapid temperature changes and catalytic reactions. Τhey perform the catalytic decomposition of hydrogen peroxide producing vigorous oxygen release and characteristic smoke‑like plumes. Using liquid nitrogen, the team freezes a banana and a rose, showing how organic structures become brittle at cryogenic temperatures. They then combine dry ice with water to generate dense CO₂ vapor, visualizing sublimation and heat transfer in real time. Through these experiments, the team transforms core chemical principles into clear, atmospheric visualizations of matter in motion.

WOW.....I absolutely loved watching your experiments. So educational, yet it looked like you all were having a lot of fun conducting them. My favorite part....freezing that flower. Thank you for warning everyone about the safety when conducting these kinds of chemical reactions.

I love it when chemistry is explained with experiments that we can see with our own eyes, rather than only through theoretical knowledge. I loved the clear explanation of all the steps and the useful knowledge you shared. Keep up the good work!

It was also great that the team reminded everyone about safety, including gloves and goggles. Well done to the Smoky Chemists for making chemistry dramatic, careful, and fun.
